SUMMARY:MEAM Seminar: “'Smart' Biodegradable Polymer at Nano and Micro Scales for Medical Applications"
DESCRIPTION:The ability to transform medical polymers\, commonly used for resorbable surgical sutures\, into desired 3D forms/shapes/structures at nano and micro scales with “smart” functions\, while sustaining the materials’ excellent biocompatibility and biodegradability\, provides significant applications in different biomedical fields\, ranging from tissue engineering and controlled drug/vaccine delivery to medical devices. Here\, I will present our recent research works to create 3D microstructures of biodegradable polymers for developing single-administered vaccines\, and convert the biopolymers into “smart” piezoelectric nanomaterials\, which can generate electricity under deformation and vice versa\, offering a variety of exciting applications in biodegradable force sensors\, tissue-engineering scaffolds and medical transducers.

SUMMARY:CIS Seminar: "Challenges of Incorporating Algorithms into Decision Making: Fairness\, Welfare and Disparate Interactions"
DESCRIPTION:Algorithms have entered the center of many decision making processes\, either by providing predictions or assessments to facilitate human decision making or\, in some scenarios\, suggesting decisions directly. More and more attention has been placed to ensure algorithms satisfy some desirable notion of fairness\, which is an important step forward. In this talk\, I will discuss the importance of examining algorithmic decision-making and algorithm-facilitated decision making in the broader context of intended applications and in the lens of human-algorithm interactions. I will first present a welfare-based analysis of fair classification algorithms to assess the welfare impact of fairness-constrained classification algorithms in the context of financial lending. Our analysis shows that applying stricter  fairness constraints in the algorithms can worsen welfare outcomes of all groups. Then\, I’ll discuss a sequence of controlled human-subject experiments studying how the interactions between people and algorithms influence human decision making. In our experiments in two contexts (pretrial release and financial lending)\, when presented with algorithmic risk assessments\, participants exhibited additional bias in their decisions and showed a change in their decision-making process by increasing risk aversion.\n\nThis talk is based on joint works with Lily Hu and Ben Green.

SUMMARY:PICS Colloquium: "Swarming bacteria as novel active biomaterials – insights into the collective mechanics\, particle transport and morphological adaptation in swarming bacteria from in-silico experiments"
DESCRIPTION:Abstract: Flagellated and motile bacteria\, in isolation or in coexistence with fungi\, are implicated in about two-thirds of human infections. During infection\, and generally even in relatively benign situations\, bacteria may colonize surfaces via a process called swarming – a form of rapid translocation associated with changes in cell phenotype.  As swarmer cells move rapidly\, they interact with each other forming cohesive structures that then rapidly develop into collective multicellular aggregates.  Understanding the swarming process is important for biomedicine\, and is relevant  to evolutional biology – in\, for instance\, understanding the evolution of phylogenetic spatial structures in bacterial populations. On a complementary note\, understanding the biophysical and mechanical aspects of swarming can provide insights into synthesizing the next generation of adaptable matter.    \nWhile comprised of independently cells\, swarms exhibit collective properties and remarkable emergent flow patterns. Recent work supports treating these collective systems as novel living biomaterials with evolving composite properties. In this talk\, I will discuss how the combination of key experimental discoveries combined with multi-scale simulations enables careful interrogation\, analysis and understanding of microbial swarms and films. The experimental component of the talk will highlight experimental observations on swarming Serratia marcescens\, a rod-shaped gram negative bacterium. Following that\, I will discuss recent work on a suite of computational approaches that we exploit to simulate these active systems. Our approaches include agent-based full-hydrodynamics simulations\, adaptations of Active Brownian Particle (ABP) stochastic models\, and mean-field continuum models solved using parallellized level-set methods on high resolution and highly adaptive Quadtree meshes.
