SUMMARY:Chemical Engineering Spring Seminar Series: Steven Wrenn
DESCRIPTION:Realizing emergent properties in functional composite from directed assembly at the micro-scale \nLocation: 108 Snell Engineering Center \nAbstract: This talk will describe fundamental studies and practical applications of biological colloids in the context of human disease. The talk will begin with endogeneous colloids and how they contribute to disease pathogenesis\, including the important roles that microstructural transitions and particle aggregation dynamics play. Specifically\, it will be shown how an incomplete transition from hepatic vesicles to bile salt micelles leads to enhanced vesicle aggregation and faster rates of cholesterol nucleation to produce gallstones and how aggregation of low density lipoproteins within the intima contributes to foam cell formation and subsequent atherosclerotic plaques. \nThe talk will then focus on how exogenous biological colloids can be designed to diagnose diseases or treat diseases\, or both. Specifically\, interactions between ultrasound\, phospholipid monolayer-coated gas bubbles\, phospholipid bilayer vesicles\, and cells will be reviewed with an eye toward diagnostic ultrasonic imaging and ultrasound-induced controlled drug delivery. Microbubble physics\, including inertial cavitation and the influence of membrane properties will be reviewed\, and a comparison between model predictions and experimental measurements will be made. Noteworthy is the predicted dependence\, or lack thereof\, of inertial cavitation on area expansion modulus through the variation of PEG molecular weight and mole fraction in the microbubble monolayer coating. \nThe talk will also involve a discussion of nesting microbubbles inside the aqueous core of vesicles and how this significantly increases the inertial cavitation threshold. The talk will conclude with an examination of the role that triglycerides play during the nesting process\, how this contributes to encapsulation efficiency\, and how this could give rise to novel microbubble architectures going forward. \n\nSteven Wrenn earned his B.S. in chemical engineering from Virginia Tech in 1991. While an under-graduate\, he worked as a co-op for G.E. Plastics (formerly Borg Warner) in Parkersburg\, WV. After graduating he worked for three years as a process engineer for Zeneca\, Inc. (formerly ICI Americas\, Inc.) in New Castle\, DE. He then returned to school\, earning his Ph.D. in chemical engineering from the University of Delaware in 1999. After graduating from Delaware\, he joined the chemical engineering faculty at Drexel University in Phil-adelphia. In 2006 he became an Alexander von Humboldt research fellow and spent a year at Ruhr University in Bochum\, Germany. In 2021 he returned to Virginia Tech to serve his alma mater as Department Head of Chemical Engineering.

SUMMARY:Chemical Engineering Spring Seminar Series: Randall Erb
DESCRIPTION:Realizing emergent properties in functional composite from directed assembly at the micro-scale \nLocation: 108 Snell Engineering Center \nAbstract: In this talk\, I will present my lab’s recent work on directing the assembly of nano- and micron- scale colloidal ceramic particles within composite materials. Through our approach\, we are able to tailor the internal microstructure of composite materials and drive meaningful changes to extrinsic properties ranging from mechanical to thermal. In the mechanical realm\, fiber orientation is a dominate factor in anisotropic property outcomes. We leverage colloidal forces ranging from shear alignment to magnetic alignment to control particle orientation. We have determined routes for applying these colloidal forces in situ to additive manufacturing. In this way\, we can construct objects that have control over complexity from the macroscale down to the micron scale. We highlight examples from bioinspired structures to theory-inspired structures to hinder crack propagation and substantially increase fracture toughness. Within the thermal realm\, we have investigated routes for controlling particle percolation pathways within thermal composites to program thermal conductivity pathways within manufactured materials. We have also pushed the limits of percolation through both volume fraction and post-sintering processes. During these studies we’ve stumbled across a new family of ceramics that are thermoformable (similar to metals and plastics). This thermoformability is reliant on the underlying microstructure which can be set into the ceramic material with new additive manufacturing processes developed in our lab. \n\nRandy Erb is a Full Professor and Associate Chair of Research of Mechanical and Industrial Engineering and the Head of the DAPS Laboratory and the RF and Thermal Laboratory at Northeastern University. Randy’s research group focuses on multiscale synthesis and characterization of functional composite materials to impact diverse fields from structural composites to energy storage to thermal management. Randy’s research group has developed new forms of AM including 3D magnetic printing\, 3D mineralization printing\, and vibration-assisted\, tape-casting DLP printing. He has received a Northeastern Translation award for converting fundamental scientific breakthroughs into successful companies. Randy has co-authored ~50 journal publications\, is co-inventor on 18 pending or issued patents\, and is a co-founder of Fortify\, Boston Materials\, and Fourier.

SUMMARY:Chemical Engineering Spring Seminar Series: Francisco Hung
DESCRIPTION:Molecular simulation of interfacial systems: From mechanical properties of liposomes to crystal nucleation in the bulk\, near surfaces and in confinement \nLocation: 108 Snell Engineering Center \nAbstract: I will give an overview of our recent molecular simulation studies of several interfacial systems of interest. In the first part of my talk\, I will describe our classical molecular dynamics (MD) simulations we used to investigate the mechanical properties of liposomes. These nanoparticles made of lipids are important in drug delivery due to their biocompatibility and ability to bolster drug stability\, amplify solubility and facilitate controlled release. While the effects of liposome size\, shape and surface chemistry on drug delivery applications have been widely studied\, liposome mechanical properties such as elasticity and rigidity remain significantly underexplored. Results from the Auguste group in our department suggest that liposome elasticity can be optimally tuned to enhance their performance in drug delivery applications. Our collaborative experimental and simulation studies aim at fundamentally understanding how the mechanical properties of the liposomes are affected by the molecular structure of the lipids\, the composition of the liposome\, and the presence of embedded hydrophobic drugs. In the second part of my talk\, I will describe MD simulations performed in collaboration with the Santiso group at North Carolina State University\, which aimed at fundamentally understanding the nucleation of crystals of ionic liquids (ILs) in the bulk and near carbon surfaces. Solidification of ILs is relevant to the synthesis of IL-based nanomaterials with desired optical and magnetic properties. In more recent collaborative efforts\, we will develop computational methods to study crystallization of a mixture of organic molecules in a solvent confined inside nanopores\, which can be used as a strategy to obtain crystals with a desired structure. Understanding how confinement in nm-sized pores affects crystal nucleation of solutes in solution will enable unprecedented control of crystallization processes\, and lead to direct benefits to society in the form of new pharmaceutical drugs and advanced energetic materials for national defense. \n\nFrancisco Hung joined the Department of Chemical Engineering at Northeastern University in Fall 2016\, from his previous position at the Cain Department of Chemical Engineering at Louisiana State University. He has an un-dergraduate degree in Chemical Engineering from Universidad Simón Bolívar in Caracas\, Venezuela\, a PhD in Chemical Engineering from North Carolina State University\, and had a postdoctoral appointment in the Department of Chemical and Biological Engineering at the University of Wisconsin-Madison prior to joining LSU. Honors include the CAREER Award from the National Science Foundation\, the LSU Rainmaker Emerging Scholar in STEM Award\, and the Richard Sioui Award for Excellence in Teaching in Chemical Engineering at Northeastern University.

SUMMARY:ChE Seminar Series: Orchestrating Cellular Regeneration at Organ Scale
DESCRIPTION:ChE Seminar Series Presents: \nYvon Woappi\, Ph.D. \nK99/R00 MOSAIC Fellow at Harvard Medical School\, Brigham and Women’s Hospital \nAbstract \nLarge scale tissue damage\, such as organ failure and burn injury\, is a leading cause of morbidity and death. However\, the mechanisms underlying full regeneration of organs remain poorly understood. As the largest organ system in the body\, the integumentary system is a composite tissue evolutionarily adapted for healing. Consequently\, its complex physiology requires multifaceted cooperation between several distinct cell populations and cell lineages of embryologically distinct origins. Equally integrated within this dynamic process is local immune response that produces mitogenic and inhibitory signals throughout the restoration procedure. There remains a significant gap in understanding how these processes are orchestrated\, and how various skin cell populations from distinct developmental lineages functionally cooperate to regenerate tissue at organ scale. My research seeks to characterize the molecular language of tissue healing and to harness this malleable dialect for the regeneration of mammalian tissues. Through the development of organoid models of wound regeneration\, and the coupling of these systems with novel gene-editing approaches\, my work is enabling the functional understanding of the multifaceted cellular events executed throughout restorative healing. This seminar will describe these high throughput technologies and will illustrate their utility in identifying novel regulators of tissue healing. \nBio \nDr. Yvon Woappi’s passion for life sciences ignited during his childhood in Douala\, Cameroon and was magnified after his family immigrated to Hanover\, Pennsylvania during his middle school years. He went on to receive his B.S in Biology at the University of Pittsburgh\, and his Ph.D. in Biomedical Sciences as a Grace Jordan McFadden Fellow under Lucia Pirisi at the University of South Carolina. There\, he developed a 3D skin organoid system to study the relationship between epithelial regeneration and virus-induced neoplasia. He subsequently completed postdoctoral training in the Harvard Dermatology Research Training Program at Brigham and Women’s Hospital where he established novel in vivo gene editing systems to understand the contribution of distinct cell lineages in tissue regeneration and cancer. He was recipient of the 2019 Engineering the Genome Award\, and was later selected as a Rising Star in biomedical sciences and engineering by MIT\, Cornell\, BU and Columbia University. Most recently\, Dr. Woappi was awarded the NIH K99/R00 MOSAIC award to launch his independent research career. Away from the bench\, he is an ardent proponent of inclusive excellence and currently sits on the advisory committee for the NIH Continued Umbrella Research Experiences Program at Harvard Medical School.

SUMMARY:ChE Seminar Series: Unwinding Anxiety: An App Based Mindfulness Program
DESCRIPTION:ChE Seminar Series Presents: \nDr. Nancy Lasson\, DO\, FACP\, DipACLM \nPrimary care provider and medical director of the primary care group at the Women’s Medicine Collaborative of LifeSpan Physician Group in Providence\, Rhode Island \nAbstract:  \nAnxiety can be managed by understanding reward-based learning and using mindfulness to interrupt unwanted behavior. Habits form to promote survival. The underlying mechanism is based on reward-based learning. There are areas of the brain where habits run on autopilot. The neo-cortex\, or new brain\, is where mindfulness can help break the cycle of unwanted habits of anxiety. Anxiety as an emotion has associated behaviors\, including worry\, rumination\, stress eating\, and smoking. The goal of unwinding anxiety is to offer an alternative to autopilot habits by employing mindfulness techniques. Multiple studies have demonstrated significant efficacy in this tool. Mindfulness is the awareness that occurs when paying attention in the present moment intentionally\, without judgment. The felt experience of mindfulness replaces autopilot habits like worry and stress. \nBio: \nDr Nancy Lasson is a primary care provider and medical director of the primary care group at the Women’s Medicine Collaborative of LifeSpan Physician Group in Providence\, Rhode Island. She is also a clinical assistant professor of medicine\, Warren Alpert Medical School at Brown University. Dr. Lasson received her B.A. at the University of Pennsylvania in religious studies and cultural anthropology. She studied medicine at the Philadelphia College of Osteopathic Medicine. She is board certified in both internal medicine and lifestyle medicine. She was a primary care physician in Limestone Medicine and Pediatrics of Christiana Care in Wilmington\, Delaware where she achieved a “Top Doctor in Delaware” award in internal medicine. She is a Fellow of the American College of Physicians and Diplomat of the American College of Lifestyle Medicine. Recently she became certified as a behavior change facilitator.  Dr. Lasson’s clinical interests include women’s medical issues and care; preventive medicine\, especially cholesterol management; coronary artery disease and cancer screening; end-of-life care for patients and their families; and mindfulness practices. She is passionate about struggles of the human soul.

SUMMARY:ChE Seminar Series: Game-Inspired Approaches to Engineering Education Across the Curriculum
DESCRIPTION:ChE Seminar Series Presents: \nDr. Daniel Burkey \nAssociate Dean of Undergraduate Education and Diversity\, Professor-in-Residence in Chemical and Biomolecular Engineering\, and a University Teaching Fellow at University of Connecticut \nAbstract: \nGame-based educational techniques can be an interesting and novel approach to active learning in engineering courses. Because games often exist within their own rule sets\, they can allow students to explore scenarios and make choices that they wouldn’t otherwise make because they are appropriate within the context and the rules of the game. In this talk\, we discuss two different projects involving game-based learning. In the first\, we explore multiple game-based approaches to teaching engineering ethics to freshmen engineering students in a multidisciplinary setting. At the beginning of the semester\, students are given a baseline survey to quantify the sophistication of their ethical reasoning. Over the course of the semester\, different game-based interventions are given to the students\, and the survey instrument again is used to determine any changes in their ethical reasoning. The game-based interventions by their nature allow students to explore ethical reasoning in the context of behavioral ethics. In the second project\, we discuss the development and use of a digital video game to teach process safety to senior chemical engineering students. Our research team developed a survey instrument to gauge the sophistication of student thinking about process safety. Students completing the survey instrument and then completing similar scenarios in the game show statistically significant differences in the types of responses they make\, indicating that different reasoning modes may be activated by the game due to its more authentic and realistic portrayal of the material. \nBio: \nDaniel D. Burkey is the Associate Dean of Undergraduate Education and Diversity\, Professor-in-Residence in Chemical and Biomolecular Engineering\, and a University Teaching Fellow at the University of Connecticut. Dr. Burkey holds his B.S. in Chemical Engineering from Lehigh University in Bethlehem\, PA\, and his M.S.C.E.P. and Ph.D. in Chemical Engineering from the Massachusetts Institute of Technology. Prior to UConn\, he held positions at Northeastern University and at GVD Corporation in Cambridge\, MA. Since joining UConn in 2010\, Dr. Burkey’s area of research has focused broadly on engineering education\, and specifically on moral and ethical development of engineering students\, process safety education\, and game-inspired educational techniques. Dr. Burkey currently serves as a Director of the Education Division of AIChE\, where he runs the Future Faculty Mentoring Program. He is a past program chair of the ASEE Chemical Engineering Division and serves on the publications board of Chemical Engineering Education. In 2020\, he was inducted into the Connecticut Academy of Science and Engineering (CASE) for his contributions to engineering education in the state. In addition to his many teaching awards\, Dr. Burkey is also the recipient of the 2020 AICHE Education Division Innovation Award for his contributions to new pedagogies in chemical engineering education\, as was recently awarded the 2021 ASEE Corcoran Award for the best paper in Chemical Engineering Education in the previous year.

SUMMARY:ChE Seminar Series: Designing Optically Active Semiconductor Nanoparticles for Biomedical Applications
DESCRIPTION:ChE Seminar Series Presents: \nDr. Allison Dennis \nAssistant Professor\, Biomedical Engineering and Materials Science and Engineering \nBoston University \nAbstract: \nAlthough the unique optoelectronic properties of semiconductor nanoparticle quantum dots (QDs) enable a variety of commercial products including display technology\, solid state lighting\, and photovoltaics\, different design criteria need to be considered to use these nanoparticles in biomedical devices. Here\, I will discuss how we tailor the composition and optical properties of QDs for a variety of biosensing and bioimaging applications. For example\, I’ll describe how we use bright red and green emitting QDs in a rapid\, instrument-free assay to detect small molecules such as antibiotics in complex water samples and use near infrared and shortwave infrared emitters to improve the clarity and resolution of in vivo imaging in mice. Finally\, I’ll describe how biodegradable and biocompatible plasmonic semiconductor nanoparticles could be used to overcome barriers to clinical translation for photoaccoustic imaging and photothermal therapy applications. Notably\, the efforts to remove heavy metals from the nanoparticles compositions also reduces the environmental impact of QDs developed for energy applications. By carefully considering material properties and engineering design choices\, we develop semiconductor nanoparticles for a wide variety of applications. \nBio: \nAllison Dennis is an assistant professor in Biomedical Engineering and Materials Science and Engineering at Boston University. After graduating with a B.S. in Bioengineering and B.A. in German from Rice University\, Prof. Dennis pursued nanobiotechnology research with Prof. Achim Göpferich in the Department of Pharmaceutical Technology at the University of Regensburg in Germany as a Fulbright Scholar. This research direction was continued during her Ph.D. work with Prof. Gang Bao at the Georgia Institute of Technology and post-doctoral research with Dr. Jennifer Hollingsworth at the Center for Integrated Nanotechnologies at Los Alamos National Laboratory. At Boston University\, the Dennis Lab engages the fundamental material properties of heterostructured semiconductor nanoparticles to optimize them for sensing\, imaging\, fundamental photophysical investigations\, and energy applications. The Dennis Lab appreciates past and current support from intramural and extramural sources including the NIH\, NSF\, and the BU Clinical and Translational Science Institute.

SUMMARY:ChE Seminar Series: Detection\, Prediction\, and Visualization of Monolayer Phase Separation on Metallic Nanoparticles
DESCRIPTION:ChE Seminar Series Presents: \nDr. David L. Green \nMaterials Science\, Chemical Engineering\, and Mechanical Engineering Departments \nUniversity of Virginia \nAbstract: The goal is to gain fundamental insights into the factors that dictate the synthesis of monolayer-protected nanoparticles and translate them into rational design strategies for novel functional soft materials. He is interested in monolayer self-assembly\, polymer grafting\, and nanoparticle dispersion. He studies how to exert control over the interface of nanoparticles\, which dictates their degree of compatibility with and assembly in soft materials\, provides reactive sites for attachment of molecules\, such as drug payloads\, and tunes detectable properties\, such as the surface plasmon to a wavelength of interest. David Green is particularly interested in the development of nanoparticles coated with monolayers from mixtures of organic molecules that may also self-assemble into advantageous patterns. As pattern formation in self-assembled monolayers is inextricably linked to their intermolecular interactions\, a key research challenge is the integration of experimental and theoretical techniques to enable de novo design of patterned nanoparticles. \nBio: David Green is an Associate Professor in the Departments of Materials Science and Chemical Engineering at the University of Virginia. He and his team collaborate with chemists\, physicists\, pharmacists\, and oncologists to develop design principles for monolayer-protected nanoparticles.

SUMMARY:ChE Seminar Series: Engineering directed Transport and Collective Dynamics of Charged Colloids under Electric Fields
DESCRIPTION:ChE Seminar Series Presents: \nDr. Carlos A. Silvera Batista \nDepartment of Chemical & Biomolecular Engineering \nVanderbilt University \nEngineering directed Transport and Collective Dynamics of Charged Colloids under Electric Fields \nAbstract: \nGradients in electrical potential (electric fields)\, along with gradients in concentration of ionic species\, are a principal way to control the motion of colloids. The surface and body forces that electric fields exert on anisotropic colloids have opened new applications in self-propulsion\, transport of cargo\, dynamic assembly\, and directed assembly. This talk focuses on the long-range transport of charged colloids\, as well as on the dynamic assembly of anisotropic and active colloids. In the first part\, we present a study of the dynamics of charged colloids under direct currents and gradients of chemical species (electrodiffusiophoresis). In our approach\, we developed a method to simultaneously visualize the progression of concentration polarization and the ensuing dynamics of charged colloids near electrodes. With the aid of confocal microscopy\, we show that the passage of current through water induce the focusing and aggregation of charged colloids away from both electrodes. Preliminary experiments show that this phenomenon can potentially be useful to perform focusing\, trapping and separation operations in lab-on-a-chip devices. In the second part\, we discuss strategies to tailor the propulsion and collective dynamics of Janus particles (JPs) under electric fields. We engineer the relaxation time of JPs by controlling the properties of the medium and the particles. The insights from this study provide helpful quantitative information for the design of colloidal machines with targeted propulsion\, interparticle interactions and collective dynamics. In addition\, our results provide the experimental basis for the design of non-equilibrium strategies for materials fabrication. \nBio: \nDr. Carlos A. Silvera Batista initiated undergraduate studies in chemical engineering at the Universidad de San Buenaventura (Cartagena\, Colombia) and subsequently obtained a bachelor’s degree from the City College of New York (CCNY). Dr. Silvera began his research trajectory as an LSAMP scholar under the guidance of Prof. Ilona Kretzschmar (CCNY). After earning a PhD in chemical engineering from the University of Florida\, Dr. Silvera held postdoctoral positions at the National Institute of Standards and Technology and at the University of Michigan\, where he received the President’s Postdoctoral Fellowship. Currently\, as an assistant professor at Vanderbilt University\, his research interest is on the electrokinetics and directed assembly of colloidal systems.  His research work has resulted in over 20 peer-reviewed publications in high-impact scientific journals\, such as JACS\, ACS Nano\, Langmuir and Science. \n

SUMMARY:ChE Seminar Series: Towards Sustainable Energy and Materials: Carbon Capture\, Utilization and Storage
DESCRIPTION:ChE Seminar Series Presents: \nDr. A.-H. Alissa Park\, Ph.D \nLenfest Earth Institute Professor of Climate Change\nDepartment of Earth and Environmental Engineering & Department of Chemical Engineering\nDirector of the Lenfest Center for Sustainable Energy\,\nColumbia University \nTowards Sustainable Energy and Materials: Carbon Capture\, Utilization and Storage  \nAbstract: \nIn order to meet the ever-increasing global energy demands while stabilizing the atmospheric CO2 level\, the development of carbon capture\, utilization and storage (CCUS) technologies is one of the critical needs. In particular\, there has been significant efforts to develop CO2 capture solvents and some (e.g.\, amine-based aqueous solvents) have shown very promising results. Unfortunately\, the energy requirement for the current aqueous solvent systems is still considered to be too high. Thus\, efforts have been focused on the development of second and third-generation CO2 capture solvents which are often water-free. Nanoparticle Organic Hybrid Materials (NOHMs) are a new class of organic-inorganic hybrids that consist of a hard nanoparticle core functionalized with a molecular organic corona that possesses a high degree of chemical and physical tunability. It has recently been discovered that NOHMs have interesting electrolyte properties which may allow the CO2 capture to be pulled by the in-situ CO2 conversion reactions. The development of these unique nanoscale hybrid materials will not only advance CO2 capture materials design but also introduce unique research opportunities in various energy and environmental fields. This seminar will discuss the challenges and opportunities of different CO2 capture and conversion pathways including Negative Emission Technologies (e.g.\, Direct Air Capture) that can allow the development of circular carbon and hydrogen economy using renewable energy. \nBio: \nAh-Hyung (Alissa) Park is the Lenfest Earth Institute Professor of Climate Change in the Departments of Earth and Environmental Engineering & Chemical Engineering at Columbia University. She is also the Director of the Lenfest Center for Sustainable Energy. Her research focuses on sustainable energy and materials conversion pathways with emphasis on integrated Carbon Capture\, Utilization and Storage (CCUS) technologies addressing climate change. Park group is also working on Direct Air Capture of CO2 and Negative Emission Technologies including BioEnergy with Carbon Capture and Storage (BECCS) and sustainable construction materials with low carbon intensity. Park received a number of professional awards and honors including the U.S. C3E Research Award (2018)\, PSRI Lectureship Award in Fluidization at AIChE (2018)\, ACS Energy and Fuels Division – Emerging Researcher Award (2018)\, ACS WCC Rising Star Award (2017)\, and the National Science Foundation CAREER Award (2009). Park also led a number of global and national discussions on CCUS including the Mission Innovation Workshop on Carbon Capture\, Utilization and Storage in 2017 and the National Petroleum Council CCUS Report in 2019. She is an elected Fellow of AIChE\, AAAS\, ACS\, and RSC. \n  \nPlease contact a.ramsey@northeastern.edu for the remote seminar link.

SUMMARY:ChE Seminar Series: Chemo-mechanics and solid-state batteries
DESCRIPTION:ChE Seminar Series Presents: \nDr. Kelsey Hatzell\, Ph.D \nAssistant Professor in the Andlinger Center for Energy and Environment \nAssistant Professor of Mechanical and Aerospace Engineering \nPrinceton University \nChemo-mechanic and solid-state batteries \nAbstract: Transportation accounts for 23% of energy-related carbon dioxide emissions and electrification is a pathway toward ameliorating these growing challenges.  All solid-state batteries could potentially address the safety and driving range requirements necessary for widespread adoption of electric vehicles. However\, the power densities of all-solid-state batteries are limited because of ineffective ion transport at solid|solid interfaces. New insight into the governing physics that occur at intrinsic and extrinsic interfaces are critical for developing engineering strategies for the next generation of energy-dense batteries. However\, buried solid|solid interfaces are notoriously difficult to observe with traditional bench-top and lab-scale experiments. In this talk\, I discuss opportunities for tracking phenomena and mechanisms in all solid-state batteries in-situ using advanced synchrotron techniques. Synchrotron techniques that combine reciprocal and real space techniques are capable of tracking multi-scale structural phenomena from the nano- to meso-scale. This talk will discuss the role microstructure plays on transport and interfacial properties that govern adhesion. Quantification of salient descriptors of structure in solid-state batteries is critical for understanding the mechanochemical nature of all solid-state batteries. \nBiography: Dr. Hatzell is an assistant professor at Princeton university in the Andlinger Center for Energy and Environment and department of Mechanical and aerospace engineering. Hatzell’s group primarily work on energy storage and is particularly interested at using non-equilibrium x-ray techniques to probe batteries during operando experimentation. \nDr. Hatzell earned her Ph.D. in Material Science and Engineering at Drexel University\, her M.S. in Mechanical Engineering from Pennsylvania State University\, and her B.S./B.A. in Engineering/Economics from Swarthmore College. Hatzell’s research group works on understanding phenomena at solid|liquid and solid|solid interfaces and works broadly i9n energy storage and conversion. Hatzell is the recipient of several awards including the ORAU Powe Junior Faculty Award (2017)\, NSF CAREER Award (2019)\, ECS Toyota Young Investigator Award (2019)\, finalist for the BASF/Volkswagen Science in Electrochemistry Award (2019)\, the Ralph “Buck” Robinson award from MRS (2019)\, Sloan Fellowship in Chemistry (2020)\, and POLiS Award of Excellence for Female Researchers (2021). \nPlease contact a.ramsey@northeastern.edu for the seminar link. \n  \n

SUMMARY:ChE Seminar Series: Materials Innovation in Nanotechnologies
DESCRIPTION:ChE Seminar Series Presents: \nDr. Paulette Clancy\, Ph.D\nHead of the Department of Chemical and Biomolecular Engineering at Johns Hopkins University \nMaterials Innovation in Nanotechnologies \nAbstract\nThere are many problems at the forefront of materials chemistry whose solution is stymied by its inherent complexity. Such problems are characterized by a rich landscape of parameters and processing variables that is combinatorially too large for either an experimental or a computational approach to solve through an exhaustive search. In such cases\, the usual approach is an Edisonian trial-and-error approach\, which inevitably leaves areas of parameter space unexplored. The problems that we have explored are also characterized by a scarcity of data\, since the data are expensive to acquire\, both experimentally and computationally. This makes it an ideal candidate to solve using a Bayesian optimization (BayesOpt) approach.\nWe have used a Bayesian approach to study several problems in self-assembly processes involving materials chemistry. This talk will discuss two mature test cases in which we used BayesOpt extensively to study (1) how to optimize the choice of solvent and halides to produce high quality thin films of lead-based hybrid organic-inorganic perovskites and (2) identify stable and metastable polymorphs of an organic semiconducting material. I will end with some ideas of where the BayesOpt field can expand its use in the chemical sciences and share some “lessons learned” in implementing BayesOpt and machine learning\, which may be helpful to others who decide to start adding machine learning to their research repertoire. \nBiography\nPaulette Clancy is a Professor and the inaugural Head of the Department of Chemical and Biomolecular Engineering at Johns Hopkins University. She is also the Samuel and Diane Bodman Professor Emerita of Chemical Engineering at Cornell. She is the Associate Director of the Hopkins Center for Integrated Structure-Materials Modeling and Simulation. She was the inaugural Director of the Cornell Institute for Computational Science and Engineering for almost 10 years and is reprising a similar role at Hopkins\, chairing our petascale research computing resources\, ARCH.\nHer research group is recognized as one of the country’s leading computational groups in atomic- scale modeling of materials and algorithm development. Her current thrust is to develop machine learning algorithms to accelerate the search for optimal materials processing protocols. Her group has always been focused on electronic materials\, but it also includes more esoteric projects include xenobiology (Life on Titan) and a screening of therapeutic oligomers to maximize antibacterial ability. She has won numerous awards for mentoring\, service learning and civic engagement\, and promoting those from under- represented groups.
