SUMMARY:ChE PhD Dissertation Defense: Peng Zhao
DESCRIPTION:Name:\nPeng Zhao \nTitle:\nImpact of ECM-Based Hydrogel Delivery Vehicle Properties on Cell Survival in a 3D In Vitro Injection Model for Retinal Progenitor Cell Transplantation \nDate:\n12/10/2024 \nTime:\n2:00:00 PM \nCommittee Members:\nProf. Rebecca Carrier (Advisor)\nProf. Abigail Koppes\nProf. Sidi Bencherif\nProf. Michael Young \nLocation:\nEXP 610-A \nAbstract:\nAge-related macular degeneration (AMD) is the leading cause of vision loss globally and a form of retinal degenerative (RD) disease. Current treatments\, such as gene therapy\, drugs\, laser procedures\, and neuroprotective approaches\, cannot restore the photoreceptors lost in RD diseases. Cell transplantation into the subretinal space shows potential to enhance visual function\, but low cell survival and efflux from the injection site present major obstacles. Mechanical forces during injection can severely damage cells\, and the host microenvironment may further contribute to cell death. Following high-density subretinal injection\, a compact cell bolus may form\, resulting in nutrient depletion\, low oxygen levels\, pH imbalances\, and waste accumulation—factors that exacerbate cell death. \nBiomaterial scaffolds have been employed to improve cell survival and differentiation\, though the ideal scaffold cues for supporting transplanted cell survival and integration remain undetermined. In this study\, we developed a three-dimensional (3D) in vitro injection model to simulate subretinal bolus injection. Using this model\, we found that the injection process and bolus microenvironment negatively impact human retinal progenitor cell (hRPC) viability\, promoting apoptosis. Alginate-based hydrogels of varying stiffness and extracellular matrix (ECM) molecule compositions were created using factorial design. hRPC viability\, apoptosis\, and migration within the formed hydrogels were investigated through the 3D in vitro injection model and a 3D invasion assay. Factorial design analysis revealed that higher stiffness and the inclusion of laminin and hyaluronic acid enhance hRPC survival and 3D migration. \nOne challenge with studying cell responses in the context of cell transplantation is the inability to easily visualize cells at the transplantation site over time. Compared to traditional in vitro cultures\, retinal explant models that retain native tissue structure and neuronal connections could provide physiologically relevant insights. Here\, we developed a novel explant model for hRPC transplantation\, wherein alginate-based hydrogels containing hRPCs were injected adjacent to cross-sectional retinal tissue slices. This setup allows visualization of the cells’ position relative to retinal tissue layers over time. Key cell behaviors\, including migration\, attachment\, invasion\, viability\, and apoptosis\, were tracked in real-time using confocal microscopy.

SUMMARY:Chemical Engineering Fall Seminar Series: Omokolade Adebowale
DESCRIPTION:Multiscale Mechanoimmunology: From Molecular Mechanisms to Precision Therapies \nLocation: 305 Shillman Hall \nAbstract: Multiscale Mechanoimmunology: From Molecular Mechanisms to Precision Therapies Therapeutic immune cells have the potential to treat complex diseases. Some therapies\, such as CAR T cells\, are effective against blood cancers but are not effective against solid cancers\, which comprise about 90% of adult cancers. A key requirement of the role of therapeutic cells in tumor eradication is their ability to migrate to and infiltrate the tumor. To accomplish this\, cells navigate various mechanoimmunological factors\, such as tissue viscoelasticity. One consequence of viscoelasticity is time-dependent stress relaxation – a decrease in stress in response to applied deformation. However\, the mechanisms by which viscoelasticity regulates migration are not fully understood. In addition\, limited studies have quantitatively compared the transport of cell therapies in tissue-like environments. My research aims to address these research gaps. To address the potential role of viscoelasticity on 3D cell migration\, I developed hydrogels that mimic the stress relaxation behavior of native tissues. I found that enhanced stress relaxation potentiates monocyte migration. Mechanistically\, our data support a model whereby WASP-mediated actin polymerization generates physical force at the leading edge of the cell to generate micron-sized channels for cells to migrate through. In a separate project\, I integrated macrophage phenotype and morphometric transitions. Together\, our studies establish a platform to determine the role of mechanical cues in shaping the immune response and to leverage fundamental mechanisms to enable the rational design of “living drugs.” \n\nKolade Adebowale will join the Shu Chien-Gene Lay Department of Bioengineering as an assistant professor in Spring 2025. Dr. Adebowale received his Ph.D. from Stanford University in 2021 under the guidance of Professor Ovijit Chaudhuri. Dr. Adebowale is a postdoctoral fellow with Professor Samir Mitragotri at Harvard University. While at Stanford\, Dr. Adebowale received the NSF GRFP\, a Stanford Graduate Fellowship\, and an NIH F31 grant. At Harvard\, Dr. Adebowale was awarded an NSF Ascend – MPS postdoctoral fellowship and was an NIH MOSAIC K99/R00 scholar. Dr. Adebowale’s main research areas are biomaterials\, mechanobiology\, and immunology. He seeks to integrate engineering design principles in cancer immunology to enable rational engineering and prediction of effective\, next-generation immune cell therapies. Furthermore\, Dr. Adebowale strives to understand how the complex functionality of the immune system arises from mechanical cues and simple biophysical principles. Dr. Adebowale is excited to teach and mentor the next generation of scientists and engineers.

SUMMARY:ChE PhD Dissertation Defense: Dominick Guida
DESCRIPTION:  \nName: \n\nDominick Guida \nTitle: \nCharacterizing and Modeling Heterogeneity in Alkaline Zn-MnO2 Batteries Using Synchrotron CT and EDXRD \nDate:\n11/25/2024 \nTime:\n11:00:00 AM \nCommittee Members:\nProf. Joshua Gallaway (Advisor)\nProf. Leila Deravi\nProf. Richard West \nLocation:\nEXP 610 and Teams \nAbstract:\nAlkaline Zn-MnO2 cells have dominated the primary battery industry for decades\, enabled by their inherent safety\, minimal environmental impact\, and low cost. Despite their widespread use\, the internal phenomena that occur within alkaline Zn anodes and MnO2 cathodes remain incompletely characterized. Within alkaline Zn anodes\, unaccounted discharge phenomena result in an inability to predict active material distribution\, internal resistance\, and eventual cell failure. In the MnO2 cathode\, heterogeneous protonation and subsequent gradient relaxation impacts cell performance\, yet remains incompletely characterized. A robust understanding of the function of alkaline Zn-MnO2 batteries is a necessary step in further improving their performance and expanding on their usefulness. \nTo better understand Zn anodes\, high resolution computed tomography (CT) was used to determine the material distribution and morphology of active phases in situ for Zn anodes discharged under various conditions. A novel algorithm was then developed to segment each individual phase from the CT data and obtain 1-D radial material distributions for direct comparison with computational modeling. The evaluation of material distributions and battery performance data provided invaluable insights on the function of alkaline Zn anodes\, including percolation effects on the Zn particle network\, maintenance of the electronic network through ZnO bridging\, and solid phase mobility due to granular flow. Identifying these phenomena have been a significant step towards elucidating the functional mechanisms within alkaline Zn anodes\, representing critical behaviors that had previously gone undetected. Not accounting for such pivotal electrode characteristics provides ample evidence as to why early modeling attempts failed to adequately capture Zn anode function. By incorporating these newly discovered phenomena\, it is now possible to predict the behavior of alkaline Zn anodes with excellent accuracy. \nIn studying MnO2 cathodes\, spatially resolved energy dispersive X-ray diffraction (EDXRD) was used to measure the heterogeneity in protonation of the active material. When using a pulsed discharge protocol\, it was identified that a significant gradient in MnO2 proton content forms across the cathode thickness during a discharge pulse and partially relaxes during a subsequent rest. The rate of gradient relaxation suggested a redox-based mechanism for proton redistribution\, which was not accurately predicted when using typical kinetic models. A fundamental kinetics experiment was performed on prismatic MnO2 electrodes\, identifying that the core-shell discharge behavior of MnO2\, where undischarged cores of MnO2 are surrounded by shells of MnOOH discharge products\, has significant implications for the reaction kinetics. As a result\, the kinetic expression used for MnO2 cathodes was modified to account for the effects of proton transport limitations induced from the MnOOH shell\, as well as kinetic effects of the active particle surface. This new expression dramatically improved MnO2 cathode model accuracy\, with simulated proton gradient formation and relaxation rates being in excellent agreement with EDXRD measurements. \nThe experimentally driven insights into alkaline Zn anodes and MnO2 cathodes have led to significant discoveries of previously unknown and uncharacterized phenomena that impact cell performance. These results were then incorporated into computational models to improve their accuracy and effectiveness\, while also representing an improved overall understanding of alkaline Zn-MnO2 batteries.

SUMMARY:Chemical Engineering Fall Seminar Series: Susan Roberts
DESCRIPTION:Molecular Engineering for Production of Anti-cancer Compounds in Plant Cell Culture \nLocation: 305 Shillman Hall \nAbstract: Our research is focused on cellular engineering and design of bioprocesses using plant-based systems. Plants produce sophisticated small molecules that play key roles in defense against predators and environmental elements. These natural products are synthesized through specialized metabolic pathways\, that have both shared and unique components when compared amongst plant systems. These specialized metabolites are useful in a variety of societal applications including as nutraceuticals\, flavorings\, colorings and pharmaceuticals. The supply of these compounds is often hindered due to low yields in nature and the inability to chemically synthesize at scale. We use plant cell culture technology as both a system of study and a scalable production system due to the ability to engineer cells and the environment to optimize accumulation of products of interest. Our group uses a combination of traditional bioprocess engineering techniques (e.g.\, bioreactor design\, cell culture\, media optimization) and modern molecular biology and analytical chemistry techniques (e.g.\, gene transfer\, transcriptomics analyses\, UPLC). Today\, I will focus my talk on molecular engineering strategies to understand and increase paclitaxel production in Taxus plant cell suspension culture. We have applied transcriptomics analyses and genetic engineering tools to understand and manipulate the pathway to paclitaxel\, identify paclitaxel transporters\, and engineer epigenetic mechanisms that can lead to decreased production over time in culture. \n\nDr. Susan Roberts is Professor and Head of Chemical Engineering at WPI.

SUMMARY:ChE PhD Dissertation Defense: Rudolf Abdelmessih
DESCRIPTION:Name:\nRudolf Abdelmessih \nTitle: \nInvestigating Strategies for Engineering More Efficient Drug Nanocarriers for Treatment of Human Metastatic Breast Cancer the Impact of Hydrophobic Drug Encapsulation on the Properties of Lipid-Based Nanoparticles and Drug Bioavailability \nDate:\n11/04/2024 \nTime:\n1:00:00 PM \nCommittee Members:\nProf. Debra T. Auguste (Advisor)\nProf. Rebecca Carrier\nProf. Stephen Hatfield\nProf. Francisco Hung\nProf. Benjamin Woolston \nLocation:\nEXP 401-A \nAbstract:\nA significant challenge in cancer treatment is the delivery of water-insoluble\, hydrophobic drugs to tumor tissue at concentrations that are therapeutically effective. One way to address this challenge is by encapsulating hydrophobic drugs into drug delivery systems that would allow them to circulate with blood and diffuse into tumor tissue. Lipid-based nanoparticles (LNPs) constitute most of the drug delivery systems currently approved for clinical use\, owing to their degradability\, lack of toxicity and their wide range of tunable properties. Liposomes are one example of LNPs; they are spherical vesicles comprised of a bilayer phospholipid membrane surrounding an aqueous core\, that can be used to encapsulate hydrophobic drugs. However\, hydrophobic drug encapsulation can change the structure and mechanical properties of the lipid\nmembrane of liposomes\, and the way they interact with cancer cells. Herein\, we investigated the impact of encapsulating different hydrophobic\, anticancer drugs into liposomes on cellular uptake\, tumor accumulation\, gene expression and tumor growth\, in metastatic breast cancer (MBC). \nOur data show that the encapsulation of an LPA receptor antagonist (Ki16425) into liposomes decreased the stiffness of the lipid membrane\, and enhanced their cellular internalization\, and tumor accumulation. Moreover\, we show that the encapsulation of an HDAC inhibitor (NVP) into liposomes increased their cellular uptake\, upregulated the expression of tumor suppressor genes\, and led to a significant cell death in MBC cells. Similarly\, we tested the effect of encapsulating an adenosine receptor antagonist (KW-6002) in a liposomal formulation that can activate cancer-related immune responses. \nIn conclusion\, our results offer insights into the chemical and mechanical behavior of drug-lipid complexes that can impact cellular internalization and tumor delivery\, and may aid in the treatment of MBC.

SUMMARY:Chemical Engineering Fall Seminar Series: Niya Sa
DESCRIPTION:Probe the Dynamic Interfaces of Beyond Lithium-ion Energy Storage Systems \nLocation: 305 Shillman Hall \nAbstract: Rapid growth of technology in the past few decades has spurred a demand for advanced energy storage devices. The invention of a more advanced battery system with higher levels of performance will be a groundbreaking discovery in the rechargeable battery field. Multivalent chemistry offers promising benefits in the development of beyond lithium-ion technologies. The direct usage of the multivalent metal anode is essential to enhance the energy density of the multivalent ion battery. For instance\, Magnesium\, Calcium and Zinc offer an immense alternative to the existing Li-ion batteries due to their multivalent nature and vast abundance in the Earth’s crust. However\, possible film formation at the solid/liquid interface complicates the electrochemical properties of such systems. The least understood solid electrolyte interphase (SEI)\, its formation and dynamic evolution has not been extensively explored for multivalent battery systems with many unknowns remain to be answered. We aim to use electroanalytical tools to probe the dynamic evolution of the solid electrolyte interface in-situ for multivalent systems and investigate its correlation with the electrochemical processes. This presentation focuses on some very recent research findings from our team for understanding the interfacial chemistry\, evolution\, and stability for different multivalent battery systems. \n\nProfessor Niya Sa is an Associate Professor in the Department of Chemistry at the University of Massachusetts Boston. She received her Ph.D. from the Analytical Chemistry (Electroanalytical Chemistry) program at Indiana University-Bloomington\, where she worked with Professor Lane A. Baker on understanding fundamental ion transport phenomena in confined regime. She extended her training working as a postdoc research fellow at the Electrochemical Energy Storage Division at Argonne National Lab. Her research focus at Argonne was to develop beyond lithium-ion battery materials. She joined the University of Massachusetts in 2017 as an Assistant Professor\, and her current research interests include probing the electrochemical interfaces for energy materials\, development of new electrolytes for next-generation energy storage systems. Niya is a recipient of the NSF CAREER Award. She also received the Endowed Faculty Career Development Award\, Joseph P. Healey Award\, and the Early Career Research Excellence Award from University of Massachusetts.

SUMMARY:Chemical Engineering Fall Seminar Series: William Tisdale
DESCRIPTION:Hybrid Semiconductor Nanomaterials \nLocation: 305 Shillman Hall \nAbstract: Hybrid organic-inorganic semiconductor nanomaterials – including colloidal quantum dots (QDs)\, 2D halide perovskites\, and metal-organic chalcogenolates (MOCs) – are excitonic materials with applications ranging from solar cells to light-emitting devices to quantum computing and quantum cryptography. In these emerging materials\, the combination of quantum and dielectric confinement\, strong exciton-phonon coupling\, and dimensionality reduction offer unprecedented opportunities for controlling light-matter-charge interactions through chemistry. In this talk\, I will describe recent work from my lab on the synthesis of hybrid semiconductor nanomaterials and our evolving understanding of how structure and chemical functionalization influence excited state dynamics. Using a combination of ultrafast laser spectroscopy\, time-resolved optical microscopy\, and kinetic modeling\, we will explore the impact of nonequilibrium population dynamics on excited state transport phenomena and the emergence of unique electronic and vibrational phenomena. \n\nWill Tisdale is the Warren K. Lewis Professor of Chemical Engineering at MIT\, where he has been teaching and leading a research team since 2012.

SUMMARY:Chemical Engineering Fall Seminar Series: Sujit Datta
DESCRIPTION:Life in a tight spot: Spying on bacteria in complex spaces \nLocation: Snell Engineering Center 168 \nAbstract: Bacteria are arguably the simplest form of life; and yet\, as multi-cellular collectives\, they perform complex functions critical to environment\, food\, health\, and industry. What principles govern how complex behaviors emerge in bacterial collectives? And how can we harness them to control bacterial behavior? In this talk\, I will describe my group’s work addressing this question using tools from soft matter engineering\, 3D imaging\, and biophysical modeling. We have developed the ability to (i) directly visualize bacteria from the scale of a single cell to that of an entire multi-cellular collective\, (ii) 3D-print precisely structured collectives\, and (iii) model their large-scale motion and growth in complex environments. I will describe how\, using this approach\, we are developing new ways to predict and control how bacterial collectives — and potentially other forms of “active matter” — spread large distances\, adapt shape to resist perturbations\, and self-regulate growth to access more space by processing chemical information in their local environments. \n\nSujit Datta is a Professor of Chemical Engineering\, Bioengineering\, and Biophysics at Caltech. Prior\, he was at Princeton University\, where he started his faculty career in 2017 and was promoted to Associate Professor of Chemical and Biological Engineering in 2022. \nSujit earned a BA in Mathematics and Physics and an MS in Physics in 2008 from the University of Pennsylvania\, and then a PhD in Physics in 2013 from Harvard\, where he studied fluid dynamics and instabilities in soft and disordered media with Dave Weitz. His postdoctoral training was in Chemical Engineering at Caltech\, where he studied the biophysics of the gut with Rustem Ismagilov. \nThe Datta Lab studies the dynamics\, self-organization\, and applications of complex\, soft (“squishy”)\, and living systems\, with a focus on complex fluids\, gels\, and bacterial communities/active matter\, motivated by challenges in biotechnology\, energy\, environment\, and medicine. Their work integrates microscopy\, microfluidics\, materials science\, and biophysical characterization with theoretical & computational modeling\, applying ideas from fluid and solid mechanics\, colloidal science\, polymer physics\, statistical mechanics\, and network science. Altogether\, this research program has revealed and shed new light on the fascinating behaviors manifested by complex fluids and bacterial populations in complex environments\, guiding the development of new approaches to environmental remediation\, energy production\, agriculture\, water security\, and biotechnology. \nSujit’s scholarship has been recognized by awards from a broad range of different communities\, reflecting its multidisciplinary nature\, including through the AIChE Allan P. Colburn and 35 Under 35 Awards\, three awards from the APS (Early Career Award in Biological Physics\, Andreas Acrivos Award in Fluid Dynamics\, and Apker Award)\, Pew Biomedical Scholar Award\, Society of Rheology Arthur Metzner Award\, ACS Unilever Award\, Camille Dreyfus Teacher-Scholar Award\, NSF CAREER Award\, and multiple commendations for teaching. In addition to leading professional activities for a number of scientific societies and agencies\, Sujit serves on the editorial boards of Annual Reviews of Condensed Matter Physics and the Journal of Non-Newtonian Fluid Mechanics.

SUMMARY:Chemical Engineering Fall Seminar Series: Matthew J. Eckleman
DESCRIPTION:Sustainability in the Chemicals Sector: From Green Synthesis to Global Systems\nLocation: 305 Shillman Hall \nAbstract: The chemicals sector is undergoing a transformation driven by decarbonization\, shifting feedstocks\, circularity\, and increasing demand for low-carbon\, non-toxic products. Globally\, chemicals production is responsible for approximately 5% of worldwide greenhouse gas emissions\, stemming from fuel combustion\, process emissions\, and product use. A wide variety of new technologies are being proposed to decarbonize chemicals manufacturing\, but in many cases their environmental benefits are not obvious and they could even have the potential to degrade other aspects of environmental quality. Robust environmental assessment of energy use\, resource inputs\, and emissions over the entire chemicals life cycle is essential for to ensure that proposed green technologies will actually deliver promised environmental benefits. \nTo aid in this\, life cycle assessment (LCA)\, techno-economic analysis (TEA)\, and related tools are increasingly being used in regulation\, certification\, and corporate decision-making.

SUMMARY:ChE PhD Dissertation Defense: Ronodeep Mitra
DESCRIPTION:Name:\nRonodeep Mitra \nTitle: \nGlycocalyx Therapy to Restore Anti-Atherosclerotic Endothelial Cell Function \nDate:\n9/11/2024 \nTime:\n9:00:00 AM \nCommittee Members:\nProf. Eno Ebong (Advisor)\nProf. Mansoor Amiji\nProf. Rebecca Carrier\nProf. Arthur J. Coury\nProf. Jessica M. Oakes \nLocation:\nEXP 610 and Zoom \nAbstract:\nThe endothelial cell (EC) glycocalyx (GCX) is a negatively charged complex sugar-rich layer that lines the endothelium. It is an important contributor to the physical and biochemical health of the vasculature and endothelium\, while mediating mechanotransduction and vascular signaling. For example\, when exposed to physiological (unidirectional and uniform in magnitude) levels of shear stress from the mechanical force of blood flow\, the GCX is abundant and aids in the production of vasodilator nitric oxide (NO)\, which regulates vascular tone. Furthermore\, the dynamics of the flow-regulated GCX determine the structural integrity of connexin proteins that comprises interendothelial gap junctions and control the flow of communication between neighboring ECs. Finally\, the GCX acts as a physical barrier to numerous components in circulating blood\, including low-density lipoproteins (LDLs) and inflammatory cells such as monocytes that differentiate into macrophages and platelets. \nLoss of the EC GCX can be attributed to disturbed vasculature blood flow patterns. This condition renders the endothelium as adhesive and permeable\, resulting in infiltration of the vessel walls by blood circulating LDLs\, compromising active EC-EC communication via interendothelial gap junctions\, and reduction in NO production\, leading to vasoconstriction. These phenotypes lead to vascular dysfunction\, atherosclerosis\, and other serious secondary cardiovascular events\, such as myocardial infarctions and strokes. Hence\, we propose either repurposing therapies that were\nnot originally indicated for GCX therapy or the development of novel GCX therapies and hypothesize that targeting the EC GCX will restore vascular function and prevent further downstream cardiovascular events\, such as atherosclerosis. \nWe first tested our hypothesis by assessing the efficacy of repurposing diosmin\, a flavanone glycoside of diosmetin\, which is a nutraceutical used to currently treat chronic venous insufficiency. Previous studies have shown diosmin’s potent anti-inflammatory and anti-oxidant properties on the endothelium. Hence\, we wanted to determine if diosmin would repair mechanically damaged endothelial GCX in regions of disturbed flow (DF) patterns and restore anti-atherosclerotic endothelium mechanotransduction function. For this study\, we utilized a unique murine in vivo DF model\, where the left carotid artery (LCA) is partially ligated\, while the right carotid artery (RCA) is not surgically intervened and was the designated uniform flow (UF) control for each mouse. Diosmin treatment elevated activated endothelial NO synthase level (p-eNOS)\, inhibited inflammatory cell uptake\, decreased vessel wall thickness and increased vessel diameter\, and increased GCX coverage on the endothelium in ligated LCA. This corroborated support that diosmin protects endothelial GCX integrity and preserves complex endothelial function. \nNext\, in vitro and in vivo DF models were used to assess a novel therapy\, combining sphingosine-1-phosphate (S1P)\, a bioactive lipid mediator\, and heparin in regenerating the endothelial GCX. We used a parallel-plate flow chamber to simulate flow conditions in vitro on human coronary arterial endothelial cells (HCAECs) and a partial carotid ligation murine model to mimic DF in vivo\, as mentioned above. In vitro data showed that heparin/S1P therapy improved the function of DF-conditioned ECs by restoring the GCX and promoting EC alignment and elevated p-eNOS expression. Furthermore\, heparin/S1P treatment restored GCX in the LCA\, enhancing GCX thickness and coverage of the blood vessel wall and reducing vessel wall thickness\, demonstrating advances in a novel therapeutic that regenerates EC GCX and restores complex vascular function in DF conditions. \nThis research work is an excellent step towards the development of repurposed or novel therapeutics that can be applied to replace\, stabilize\, or protect the GCX and restore GCX-mediated EC mechanotransduction\, particularly in DF conditions. These prospective mechano-therapeutics could represent breakthrough solutions for preventing cardiovascular diseases such as atherosclerosis in the future.

SUMMARY:ChE PhD Dissertation Defense: Mohammad Hamrangsekachaee
DESCRIPTION:PhD Dissertation Defense: Endothelial Glycocalyx: Response to Fluid and Solid Mechanics in its Environment \nMohammad Hamrangsekachaee \nLocation: Snell Library 033 and Zoom \nAbstract: Atherosclerosis\, a precursor to cardiovascular diseases (CVDs)\, accounts for 37% of deaths in individuals under 70 years old\, primarily due to endothelial cell (EC) dysfunction. The glycocalyx (GCX)\, a carbohydrate-rich structure on ECs lining the vessel luminal surface\, is crucial for EC function and vascular health by regulating vascular tone\, hemostasis\, permeability\, and mechanotransduction. Therefore\, cellular models emulating the vascular mechanical environment are vital for understanding GCX’s role and its interaction with mechanical surroundings. This dissertation introduces an innovative in vitro model to investigate the combined effects of tissue stiffness and shear stress on endothelial cell function. \nTunable non-swelling gelatin-methacrylate (GelMA) hydrogels were fabricated with stiffnesses of 2.5 and 5 kPa\, representing healthy vessel tissues\, and 10 kPa\, corresponding to diseased vessel tissues. Immunocytochemistry analysis showed that on hydrogels with different levels of stiffness\, the GCX’s major polysaccharide components exhibited dysregulation in distinct patterns. For example\, there was a significant decrease in heparan sulfate expression on pathological substrates (10 kPa)\, while sialic acid expression increased with increased matrix stiffness. \nGelMA hydrogels were then integrated into a flow chamber designed to generate physiological flow conditions. The combined effects of fluid shear stress and substrate stiffness were analyzed for heparan sulfate\, sialic acid\, hyaluronic acid\, syndecan-1\, CD44\, and YAP. Under shear stress\, heparan sulfate’s coverage was reduced at 10 kPa\, while sialic acid and CD44 expression increased at 10 kPa. YAP activation\nshowed increased nuclear translocation and decreased phosphorylation at 10 kPa. Our findings revealed that substrate stiffness and mechanical forces significantly influence GCX expression and endothelial cell function. \nThis research highlights the critical role of the mechanical environment on GCX in vascular health\, particularly in the context of atherosclerosis. By developing an innovative in vitro model that integrates tissue rigidity and shear stress\, we have provided a more precise simulation of the vascular environment. This model offers a valuable tool for further understanding EC mechanotransduction and developing targeted treatments for cardiovascular diseases.

SUMMARY:Chemical Engineering Summer Sustainability Seminar Series: Ewa Marek
DESCRIPTION:Chemical looping for sustainable production of chemicals \nThe chemical industry is centred on the processing of crude oil and is responsible for the lion’s share of greenhouse gas emissions. Running industrial-scale installations requires huge energy inputs\, employing high temperatures\, pressures\, and\, often\, explosive mixtures. The current industry is designed to work continuously\, using cheap\, petrochemical feedstock. Switching the starting point and moving from oil to renewable feedstock\, whether it is bio-derived carbonaceous material\, captured CO2\, or renewable electricity\, requires new decentralised and flexible operations\, as all these resources are spatially distributed and available intermittently. Our work focuses on small-scale\, dynamic processes\, developing and employing new reaction and process pathways to produce key chemicals. This talk will present our work using a chemical looping approach where solid particles of metal oxides are the sole source of oxygen to catalytic reactions. In particular\, I will discuss the chemical looping epoxidation (CL-E) of ethylene to produce ethylene oxide (EO) and chemical looping oxidative dehydrogenation (CL-ODH) of ethanol to produce acetaldehyde. \n\nBio \nDr. Ewa Marek is an associate professor at the Department of Chemical Engineering and Biotechnology\, University of Cambridge and a fellow of Jesus College. She leads the Energy Reactions and Carriers Group\, working on the production of value-added chemicals from intermittently available renewable feedstock and electricity\, incorporating non-thermal plasma\, ultrasounds and chemical looping to drive efficient\, transient processes. This work led to 2021 Hinshelwood Prize and 2023 Energy&Fuels Rising Star Award for early-career academics. Before setting up her group\, she was a post-doctoral associate in the Engineering Department\, Cambridge\, and earlier\, she worked for six years on industrial R&D and advanced measurement methods in the UK\, Netherlands and Poland. She studied energy and chemical processing (BEng\, MSc) in Cracow and carbon capture (PhD) in Katowice (both in Poland). \nLinks \nhttps://www.ceb.cam.ac.uk/staff/dr-ewa-marek \nhttps://www.jesus.cam.ac.uk/people/ewa-marek

SUMMARY:ChE PhD Dissertation Defense: Ian Smith
DESCRIPTION:PhD Dissertation Defense: A Primary Intestinal Model to Assay Lymphatic Drug Transport \nIan Smith \nLocation: Dodge Hall 070 & Zoom \nAbstract: Lipophilic drugs (logP > 5) often fail to develop as commercial oral medications due to poor absorption\, distribution\, metabolism\, excretion and/or toxicity (ADMET) properties. Beyond-rule-of-5 (bro5) candidate attrition in the clinic may be relieved by targeted delivery to chylomicrons (CMs) as chaperones into the mesenteric lymphatics. Lymph-cannulated animal models that estimate lymphatic bioavailability (F%) are surgically challenging\, costly and highly variable between species. In vitro models of the human intestinal epithelium can preserve enterocyte-like CM assembly and thereby recapitulate on the benchtop drug intercalation with CM components during transcytosis (i.e. the “lymphatic permeability” mechanism). This thesis proposes primary small intestinal epithelia as alternative platforms to the Caco-2 Transwell® culture for assaying lymphatic drug transport. \nPrimary monolayers cultured from small intestinal enteroids were investigated for CM synthesis\, secretion\, and transport of lymphotropic small molecules. The specific aims were to: 1) establish a mixed bile micelle formulation compatibile with primary cultures\, 2) develop a first-principle mathematical description of poorly water-soluble drug (PWSD) partitioning and uptake from lipid-containing micelles\, 3) characterize apolipoprotein B (apoB)-containing lipoprotein secretion from primary cultures along an oleic acid (OA)/2-monoloein (2-MO) stimulation axis\, and 4) compare CM-transported drug in culture to lymph-cannulated F% estimations. Exposure of mixed bile micelles containing 4:1 taurocholate (TC) and phosphatidylcholine (PC) to the brush border membrane of human duodenum (hDuo) and Caco-2/HT29-MTX co-cultures (Co-C) compromised tight junctional resistance and paracellular permeability in Co-C above 5 mM TC whereas hDuo were unaffected. Permeability measurements in the Co-C monolayer showed PWSD transport from TC/PC micelles to be reasonably predicted by changes in the apical (i.e. lumen-side) free or total drug concentration (CD\,free or CD\,total)\, but extent of fatty acid (FA)-induced supersaturation was limited by lipo-toxicity. Over a time course aligned to the window of lymph triglyceride (TG) turnover in vivo (i.e. 6 hours)\, controlled 2-monooloein (2-MO) stimulation of hDuo and murine ileum (mIle) monolayers induced significant increases in TG mass (~3.5-fold) and particle diameter (Dh) (~2-fold) of  < 1.006 g/mL lipoproteins. Primary enterocytes upregulated mgat2 transcription in the presence of 2-MO substrate to indicate that TG output in these FBS-differentiated cultures engaged the sn-1\,2-monoglyceride (2-MG) re-esterification pathway. Organoid cultures also favored basal-polarized apoB-48 release distinct from the bidirectional apoB-100 output of Caco-2. Finally\, apparent permeability of halofantrine (Hf; logP 7.34; BCS Class II) and navitoclax (Nx; logP 7.93; BCS Class IV) in CMs secreted from mIle but not Caco-2 were increased from TC/PC control conditions by inclusion of +OA/2-MO in micelles. For Hf\, the fraction of dose absorbed by CMs (faCM = 6.8 ± 0.9%) was similar to the fraction of dose transported into the lymph of cannulated rats (falymph = 5.5 ± 0.8%). \nDevelopment of an in vitro-in vivo correlation between lymph-cannulated animals and the primary transport assay developed herein might assist preclinical programs in translating lipid-based oral modalities to humans. Expansion of the organoid donor set (by species and small intestinal region)\, combinatorial probing of more lipid stimulation axes (by substrate chain length and saturation)\, and scaling of monolayer culture could refine the lymphatic assay into a high-throughput screen. Beyond a drug delivery context\, de novo CM assembly in enterocytes that retain a native small intestinal phenotype enables closed-system study of outstanding questions regarding intestinal lipoprotein formation and dyslipidemia disease intervention.

SUMMARY:Chemical Engineering Spring Seminar Series: Dr. David Brayden
DESCRIPTION:Oral administration of peptides: The quest to improve bioavailability \nThe oral administration of peptides and proteins remains one of the great challenges in pharmaceutical science. Efficacy depends on patients committing to take essential medicines and this is built upon the convenience of a dosing regimen using a patient-friendly route of administration. Large molecules have problems negotiating the GI tract to achieve systemic delivery due to instability against metabolizing enzymes and low permeability across the epithelium. To date\, just five linear peptides aimed at systemic delivery have been approved by the FDA\, the most recent being oral semaglutide (Rybelsus®\, Novo Nordisk\, 2019) and oral octreotide (Mycappsa®\, Chiasma Ltd\, 2020). These approvals heralded a renewed interest in the field\, built around developing Glucagon-1-like peptide 1 (GLP-1) mimetics for Type II diabetes and obesity\, alone or as a dual agonist with other gut peptides. Relative success to date for oral peptides has been achieved with standard oral dosage forms made with permeation enhancers\, but these will only work for niche peptides with high potency and long half-lives. \nMy group has been working on the mechanism of action of the intestinal permeation enhancers that typically are used to enable these formulations\, albeit that oral bioavailability with the above products is less than 1%. We have focussed on comparisons between sodium caprate and SNAC\, both medium-chain fatty acid derivatives\, and found that they have multimodal actions suggesting a dual effects on tight junctions and the intestinal epithelial plasma membrane depending on the concentration and the bioassay. We also have contributed to the search for other permeation enhancers (alone and combination) that can be used with peptides in oral dosage forms including the Gattefosse excipients\, Labrasol® and Labrafac™. We are working on a nanotechnology concept\, where we have achieved 7% bioavailability for insulin in a rat model using a core-shell construct based on silica coating over a core of peptide and the excipients\, L-arginine\, and zinc. Finally\, devices may eventually be able to increase the oral bioavailability of peptides by an order of magnitude over permeation enhancers according to data from animal models\, but clinical testing is at an early stage and the toxicology and the regulatory pathway for these types of technologies have yet to be addressed. I will touch on aspects and examples of these multiple approaches in my talk at Northeastern. \n\nDavid Brayden is Full Professor of Advanced Drug Delivery at the School of Veterinary Medicine and a Fellow of the UCD Conway Institute.

SUMMARY:Chemical Engineering Spring Seminar Series: Dr. Jodie Lutkenhaus
DESCRIPTION:Organic Batteries for a More Sustainable Future \nCobalt\, nickel\, and lithium are essential ingredients in today’s lithium-ion batteries (LIBs)\, but their continued use presents economic\, ethical\, and environmental challenges. Society must now begin to consider the implications of a LIB’s full life cycle\, including the carbon footprint\, the economic and environmental costs\, and material access. These challenges motivate the case for degradable or recyclable batteries sourced from earth-abundant materials whose life cycle bears minimal impact on the environment. This presentation considers organic polymer-based batteries\, which have the potential to address many of these issues. Redox-active polymers form the positive and negative electrodes\, storing charge through a reversible redox mechanism. We demonstrate polypeptide radical batteries that degrade on command into amino acids and by-products as a first step toward circular organic batteries. Further\, we show the recycling of redox-active polymer electrodes using a solvent-based approach. Polymer-air batteries are examined as high-capacity alternatives to metal-air batteries. The molecular mechanism for each case is investigated\, revealing pathways forward for improving each polymer’s performance. Taken together\, organic batteries offer the promise of a circular platform free of critical elements. \n\nJodie L.

SUMMARY:Chemical Engineering Spring Seminar Series: Dr. Sindia M. Rivera Jiménez
DESCRIPTION:Professional Organizations and Social Responsibility in Chemical Engineering Education \nProfessional organizations (POs) are established communities that significantly influence the competencies and values of engineers\, but the impact of their interaction with academia on undergraduate education is not fully understood. This study addresses this gap by exploring how engineering faculty in POs strategically incorporate social responsibility into their teaching. Relying on Paulo Freire’s critical consciousness and the Transformational Agency framework\, it examines faculty reflections on societal and power dynamics for curriculum change. \nConducted over eight months\, the study focuses on a Community of Practice (CoP) within the American Institute of Chemical Engineering’s Education Division\, engaging faculty from multiple institutions. We employed qualitative methods\, analyzing interview data through thematic analysis with In-Vivo and Axial coding. Preliminary results highlight how the CoP influences faculty’s reflective practices and understanding of societal structures\, suggesting it enhances educators’ critical awareness and ability to integrate social responsibility into their teaching. \nThe findings deepen our understanding of POs’ role in evolving engineering education. They showcase how educators’ involvement in POs can shape socially responsible engineers\, addressing the complex societal roles engineers face. This seminar aims to inspire educators with strategies for creating transformative learning environments. \n\nDr. Rivera-Jiménez is an Assistant Professor in the Department of Engineering Education at the University of Florida and is affiliated with the Department of Chemical Engineering and the Institute of Higher Education. Her research group focuses on community-driven methods to improve practices and policies that enhance the professional formation of engineers and impact the success of diverse engineering communities\, including faculty\, undergraduate and graduate students\, and transfer students. Current projects include faculty support via professional societies\, student motivation and emotions in blended learning\, and studying diverse transfer student success within organizational contexts. \nAdditionally\, she hosts “The Engineering Professor Speaks Education Podcast\,” a bilingual series exploring the nuances of being an effective engineering educator. Her most recent accolades include the AIChE IDEAL Star Award (2021)\, the AIChE Education Division Service Award (2022)\, and the ASEE Education Research Methods Apprentice Faculty Grantee Award (2023).

SUMMARY:Chemical Engineering Spring Seminar Series: Dr. Christina Chan
DESCRIPTION:Role of microenvironment on mediating diseases\, DNA repair\, and lipid alterations \nOur group incorporates metabolic engineering and systems biology approaches in combination with biochemical and molecular biology measurements to identify targets and disease biomarkers. To modulate these targets and pathway we are concomitantly developing polymeric-based drug delivery systems. \nWe apply a multifaceted approach in investigating the role of soluble cues (e.g.\, elevated fatty acid levels\, PFAS) in the microenvironment on modulating the signaling and regulatory pathways that contribute to diseases. These extracellular signals are mainly in the form of soluble factors that activate intracellular signaling cascades that drive changes in the cell. Our group has identified that saturated fatty acids (i.e.\, palmitate)\, which are well studied for their roles in metabolism\, can also activate signaling pathways that affect proteostasis. Through biochemical and biophysical studies\, we found that palmitate binds directly to proteins involved in proteostasis to modulate their activity and downstream signaling to alter DNA repair\, which has implications on chemotolerance\, lipid profile\, and heart disease. \n\nChristina Chan is a University Distinguished Professor and Interim Chairperson of Chemical Engineering at Michigan State University (MSU). She also has appointments in the Departments of Biochemistry and Molecular Biology\, Biomedical Engineering\, and Computer Science and Engineering. Prior to joining MSU in 2002\, she was a post-doctoral fellow at the Center for Engineering in Medicine at the Harvard Medical School. Chan earned her B.S. in Chemical Engineering from Columbia University and her M.S. and Ph.D. in Chemical and Biochemical Engineering from the University of Pennsylvania. She spent 8 years in DuPont prior to returning to academia. Her laboratory applies a multifaceted approach in investigating the role of soluble cues in the microenvironment on modulating the signaling and regulatory pathways that contribute to diseases. To modulate these targets and pathways\, her laboratory is developing polymeric-based drug delivery systems as well as tissue engineering platforms that capitalize on how scaffolds\, cells\, and biologically active molecules interact to form functional tissues. Her group has published more than 165 journal articles\, reviews\, book chapters and reviewed conference papers. She was elected Fellow of the American Institute of Medical and Biological Engineering (AIMBE)\, AIChE\, and AAAS.

SUMMARY:Chemical Engineering Spring Seminar Series: Dr. Michael Murrell
DESCRIPTION:Energetic Constraints on Biological Assembly and Motion \nOn small length-scales\, the mechanics of soft materials may be dominated by their interfacial properties as opposed to their bulk properties. These effects are described by equilibrium models of elasto-capillarity and wetting. In these models\, interfacial energies and bulk material properties are held constant. However\, in biological materials\, including living cells and tissues\, these properties are not constant\, but are ‘actively’ regulated and driven far from thermodynamic equilibrium. As a result\, the constraints on work produced during the various physical behaviors of the cell are unknown. Here\, by measurement of elasto-capillary effects during cell adhesion\, growth\, and motion\, we demonstrate that interfacial and bulk parameters violate equilibrium constraints and exhibit anomalous effects\, which depend upon a distance from equilibrium. However\, their anomalous properties are reciprocal\, and thus in combination reliably define energetic constraints on the production of work arbitrarily far from equilibrium. These results provide basic principles that govern biological assembly and behavior. \n\nMichael Murrell received his BS at Johns Hopkins University and his PhD at MIT. He then had a joint postdoctoral fellowship between the Institute for Biophysical Dynamics at the University of Chicago\, and the Institut Curie\, in Paris\, France. He now runs the Laboratory for Living Matter within the Systems Biology Institute at the Yale West Campus\, as part of the Biomedical Engineering and Physics Departments. His laboratory studies the non-equilibrium properties of biological systems\, as well as designs and engineers novel bio-inspired materials. His group comprises a diverse group of experimentalists\, computational scientists\, and theorists all driven to understand some of the most fundamental questions in biophysics.

SUMMARY:Chemical Engineering Spring Seminar Series: Jason E. Bara
DESCRIPTION:Sustainability through Plastic Upcycling and Molecular Design of Green Solvents \nThis talk will give overviews of two relatively new research areas in the group of Prof. Jason E. Bara. First\, efforts in plastic waste depolymerization and upcycling will be discussed with a focus on progress that is being made in two particularly challenging materials: poly(vinyl chloride) (PVC) and polyurethanes (PU). As PVC is the 3rd-most produced plastic worldwide\, it is also very different than other commodity polyolefins including polyethylene (PE) and polypropylene (PP). PVC offers unique opportunities for chemistry (via depolymerization and functionalization) as well as solubility behaviors which enable it to be fractionated which can be advantageous and enable new applications for waste PVC\, including 3D printing. Bara’s group is also developing a new process dubbed “imidazolysis” which can break down crosslinked PU materials with recovery of small molecules. With respect to the design of green solvents\, this talk will illustrate how Bara and collaborators are utilizing molecules with glycerol “skeletons” to tackle challenges in CO2 capture (including direct air capture (DAC))\, batteries\, plastic wastes\, additive manufacturing\, and extractions of lithium and other critical materials from dilute sources. \n\nJason received a B.S. in Chemical Engineering from Virginia Commonwealth University and a Ph.D. in Chemical Engineering from the University of Colorado at Boulder. He has authored more than 160 peer-reviewed research publications on the topics of separations\, ionic liquids\, polymer membranes\, and chemical process engineering. He has also been awarded 15 U.S. patents for new technologies developed in these areas. In recognition of his research\, he received the Permeance Prize for Mid-Career Excellence from the North American Membrane Society (NAMS) (2024)\, Early Career Fellow from the Industrial & Engineering Chemistry Division of ACS (2021)\, the Membranes (MDPI) Young Investigator Award (2020) and the FRI/John G. Kunesh Award from the Separations Division of AIChE (2015). Jason has also been recognized for his contributions to chemical engineering education as the 2018 recipient of the Ray W. Fahien Award from ASEE and the 2017 recipient of the David Himmelblau Award for Innovations in Computer-Based Chemical Engineering Education Award from AIChE. \nZoom Link

SUMMARY:Chemical Engineering Spring Seminar Series: Prashun Gorai
DESCRIPTION:A Journey from Atoms to Materials: Designing Functional Materials for Energy and Microelectronics \nTechnological developments often rely on specifically designed materials and molecules. The increasing pace of technology development\, coupled with rising energy needs and climate challenges\, requires faster approaches for materials discovery. Historically\, materials have been discovered by trial-and-error approaches that rely on chemical intuition. Designing materials with tailored properties is challenging because of the astronomical number of possible compounds and structures\, and materials behaviors that do not adhere to standard chemical intuition. \nComputations have made great strides in accelerating materials development\, but many challenges remain. We are addressing some of these challenges\, including inverse materials design and bridging the gap between theoretical predictions and real materials. In this talk\, I will share examples from our work on the computational discovery and design of functional materials\, as well as modeling of defect and doping properties of semiconductors. \n\nDr. Prashun Gorai is a research assistant professor at the Colorado School of Mines (CSM) with a joint appointment at the National Renewable Energy Laboratory (NREL). He obtained his bachelor’s degree in Chemical Engineering from IIT Madras (India)\, and his PhD\, also in Chemical Engineering\, from the University of Illinois at Urbana-Champaign. He was a postdoctoral fellow at CSM and NREL between 2014-2017. His research team uses quantum-chemical calculations\, high-throughput computing\, and machine learning to discover and design functional materials for energy conversion and storage\, and next-generation microelectronics. The International Thermoelectric Society awarded him the Young Investigator Award in 2022 and the Royal Society of Chemistry (Materials Horizons) recognized him as an Emerging Investigator in 2020. He is a recipient of the Chemistry of Materials Lectureship and Best Paper Award 2023.

SUMMARY:Chemical Engineering Spring Seminar Series: Adam Caparco
DESCRIPTION:Protein-based materials for sustainable bioprocesses \nProtein materials\, whose function can be programmed by their amino acid sequence\, possess the potential to address many societal challenges by providing a sustainable and biocompatible alternative to many traditional materials. As an example\, the enhancement of enzymes for biocatalysis serves as a gateway for more sustainable chemical manufacturing. I will demonstrate that by designing an enzyme to fuse to a solid support material\, we can vastly improve its stability and recover the material between reactions for multiple uses. Protein materials also serve as a platform for targeted delivery in medicine and agriculture. I will show that by transforming inactivated plant viruses into spherical nanoparticles for encapsulation\, hydrophobic agrochemicals can be delivered through the soil and paralyze roundworms for pest management with high efficacy. \n\nAdam Caparco\, Ph.D. is a postdoctoral scholar at the University of California\, San Diego in the Department of NanoEngineering. His research under Prof. Nicole Steinmetz is funded by a USDA NIFA fellowship and is focused on using plant virus nanoparticles as agricultural delivery systems for pest management and genetic engineering of plants. Prior to this position\, Dr. Caparco completed his doctoral work in Biomolecular Engineering at Georgia Institute of Technology under Profs. Julie Champion and Andreas Bommarius\, where he focused on using self-assembled protein materials for sustainable biocatalysis. During his doctoral studies\, he was awarded a STEM Chateaubriand fellowship and worked with bioinformaticians and biochemists at Genoscope in France. As an undergraduate\, Dr. Caparco studied Chemical and Biomolecular Engineering at the University of California\, Los Angeles.

SUMMARY:Chemical Engineering Spring Seminar Series: Angela Chen
DESCRIPTION:Engineering Microbial Communication for Sustainable Agriculture \nAgriculture and the global food system accounts for ~30% of greenhouse gas emissions. Therefore\, developing sustainable agricultural technologies is essential for combating and mitigating the effects of climate change. Microbes like bacteria and fungi play pivotal roles in agriculture and food security through complex interactions with plant hosts\, other microorganisms\, and their surroundings. Consequently\, my research aims to investigate how these inter-species and cross-kingdom relationships could be ideal engineering targets for addressing current agricultural challenges. In this seminar\, I will present my work showcasing the power of RNA and nanotechnology in manipulating microbial interactions with the environment and plant hosts. In the first part of my talk\, I will examine how microbes respond to environmental stresses and the use of regulatory RNAs as a genetic platform to manipulate bacterial metal reduction capabilities for the biosynthesis of nanoparticles with unique and enhanced functionality. Following this\, I will then discuss host-microbe interactions and how exploiting RNA-based communication between fungal pathogens and plant hosts can inform next-generation\, nanoparticle-based strategies for plant disease control. Together\, these studies illustrate how understanding and controlling microbial communication will pave the way for new sustainable strategies for reducing agricultural chemical dependence\, improving plant health\, and enabling bioremediation technologies. \n\nAngela Chen is a USDA-NIFA AFRI Postdoctoral Fellow in the Department of Microbiology and Plant Pathology at UC Riverside. Under Prof. Hailing Jin\, she investigates the mechanisms of cross-kingdom RNA trafficking between plants and fungal pathogens to develop nanomaterials for RNAi-based disease control. Prior to UC Riverside\, she received her B.S. in chemical engineering from the Ohio State University and her M.S. and Ph.D. in chemical engineering from the University of Texas at Austin. As an NSF Graduate Research Fellow with Profs. Lydia Contreras and Benjamin Keitz\, she focused on engineering regulatory RNAs in extremophilic bacteria to control bacterial stress response for materials science applications. Outside of research\, Angela is passionate about educating and empowering the next generation of engineers\, having earned a Graduate Certification in Engineering Education. She is also the President of the Riverside Postdoctoral Association\, where she leads initiatives focused on supporting postdocs and broadening STEM access through the creation of diverse and inclusive academic environments.
