Holloway DESCRIPTION:ChE Seminar Series Presents:  \nJulianne L. Holloway\, Ph.D\nAssistant Professor in Chemical Engineering\nSchool for Engineering of Matter\, Transport and Energy\nArizona State University \nAbstract: \nAdvances in materials science\, biomolecule delivery\, and cell biology has enabled significant innovations within the field of tissue engineering and regenerative medicine over the past few decades. Nonetheless\, minimal translation of tissue engineering-based therapeutics to the clinic has occurred. \nA significant challenge within tissue engineering is the difficulty in regenerating complex tissues with a heterogeneous structure and multiple cell types. To address this challenge\, my research group is developing innovative polymeric biomaterials that can mimic the complex microenvironment of musculoskeletal tissues. \nSpecifically\, I will discuss our recent efforts in the following areas: 1) using magnetic fields to spatially control electrospun fiber alignment in order to create materials with gradients in fiber alignment that mimic the structure of musculoskeletal interfacial tissues; 2) using reversible DNA handles to temporally control peptide presentation to improve our understanding of cell- material interactions; and 3) combining these techniques for independent spatial control over chemical and structural signals towards simultaneous regeneration of multiple tissue types. \nBio: \nJulianne Holloway is an Assistant Professor of Chemical Engineering at Arizona State University (ASU) and an associate faculty member within the Biodesign Institute’s Center for Molecular Design and Biomimetics. \nPrior to ASU\, Julianne completed her Ph.D. in Chemical Engineering at Drexel University and her postdoctoral training at the University of Pennsylvania. \nJulianne’s research group integrates biomaterial design with innovative manufacturing to control and direct stem cell behavior for tissue engineering and regenerative medicine applications. \nJulianne is also committed to service\, including recent election to the American Institute of Chemical Engineers (AIChE) Board of Directors\, serving on the Editorial Board of Regenerative Biomaterials\, and as a past Associate Scientific Advisor for Science Translational Medicine.

First predicted for rods\, and then spheres\, the thermodynamic ordering of hard shapes by nothing more than crowding is now well established. In recent years\, surprising discoveries of entropically ordered colloidal crystals of extraordinary structural complexity have been predicted by computer simulation and observed in the laboratory. Colloidal quasicrystals\, clathrate structures\, and structures with large and complex unit cells typically associated with metal alloys\, can all self-assemble from disordered phases of identical particles due solely to entropy maximization. In this talk\, we show how entropy alone can produce order and complexity beyond that previously imagined\, both in colloidal crystal structure as well as in the kinetic pathways connecting fluid and crystal phases\, and we show how methods used by the quantum community to predict atomic crystal structures can be used to predict entropic colloidal crystals. \nPlease email Alyssa Ramsey at a.ramsey@northeastern.edu for the link to the seminar.

Vlahovska\, PhD\nProfessor of Engineering Sciences and Applied Mathematics (by courtesy)\nMechanical Engineering\, Northwestern University \nTitle: Active colloidal fluids: a new paradigm in self-assembly \nAbstract: \nFlocks of birds and schools of fish are familiar examples of emergent collective behavior\, where interactions between self-propelled (active) individuals lead to coherent motion on a scale much larger than the isolated unit. Similar phenomena have been observed with active micro-particles such as bacteria and motile colloids.  Recently\, the Quincke instability (spontaneous spinning of a dielectric particle in an applied uniform DC field) has attracted great interest as a means of propelling colloids\, by simply letting the particles roll on a surface.   In this talk\, I will present our experiments showing how Quincke rollers\, previously studied mainly as active Brownian particles\, can be designed to perform Run-and-Tumble-like locomotion mimicking bacteria such as E. coli. Populations of the Quincke random walkers self-organize and exhibit behaviors reminiscent of bacterial suspensions such as dynamic clusters and mesoscale turbulent-like flows. When enclosed in a drop\, the Quincke rollers drive strong shape fluctuations and drop motility resembling amoeba crawling. I will also discuss some novel collective dynamics of Quincke rotors levitating in a bulk fluid: unlike the rollers\, the “hovers” form crystals\, chains and other dynamical assemblies. \nBio: \nPetia M. Vlahovska received a PhD in chemical engineering from Yale (2003) and MS in chemistry from Sofia University\, Bulgaria (1994). She was a postdoctoral fellow in the Membrane Biophysics Lab at the Max Planck Institute of Colloids and Interfaces and spent ten years on the faculty at Dartmouth College and Brown University\, before joining the faculty at Northwestern University in 2017. Her research is in fluid dynamics\, membrane biophysics\, and soft matter. Dr. Vlahovska is the recipient of David Crighton Fellowship (2005)\, NSF Career Award (2009) and a Humboldt Fellowship (2016). In 2019\, she was elected fellow of the American Physical Society. \nPlease email Alyssa Ramsey at a.ramsey@northeastern.edu for the link to the seminar.

White\, Ph.D \nProfessor and Chair of Biomedical Engineering\, Boston University \nEngineering Approaches to Understand Functional Connectivity in Neocortex \nAbstract\nThe mammalian neocortex is a crowning achievement of evolution. It is astronomically complex\, with around 100 billion computational elements\, each of which is staggeringly intricate by itself\, and on the order of 1016 synaptic connections. In this talk\, I plan to examine three questions related to the neocortex. First\, what are the consequences of component miniaturization for neural computation? Second\, how can we model neural computation on such a scale in a way that makes tractable predictions? Third\, what does distributed neural computation “look like?” The bulk of the talk will focus on testing strong predictions from the relatively simple stabilized supralinear network (SSN) model of how neocortical networks behave in resting wakefulness\, and how that behavior changes when the network is activated by sensory input or intentional movement. Our data are collected from mouse somatosensory cortex\, mainly under whole-cell patch clamp\, but also using genetically encoded calcium indicators. Our results are mainly compatible with the SSN model. \nBiography\nJohn A. White is Professor and Chair of Biomedical Engineering at Boston University.
