MEAM Seminar: “Role of Water in the Mechanics of Cells and Tissues”

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

A large fraction of cell and tissue mass is made of water. The flow of water across the cell surface follows osmotic and hydraulic pressure gradients, and is actively controlled by the cell. This physical fact suggests that the mechanical behavior of cells is intimately connected with cell ionic homeostasis and osmotic control. In this […]

MSE Seminar: “Building With Fluids: A Lazy Approach to Fabrication”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

In nature, organized arrays of elements arise spontaneously from the interactions between their component parts, e.g. reaction-diffusion problems, clustering colloidal particles and granular media, wrinkling surfaces, propagating cracks and flowing liquids. In the wake of biomimicry, I will discuss several strategies aiming to harness mechanical instabilities in flowing liquids, e.g. coiling, droplet formation, digitation, drainage, […]

MEAM Seminar: “Multifunctional Soft Materials for Electronics, Robots, and Adhesives”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Multifunctional soft materials and interfaces create intriguing new opportunities to enhance performance through programmable and adaptable properties. I will discuss: 1) Novel material architectures of solid-liquid soft composites for electronics, 2) Switchable and programmable materials for adhesion control, and 3) Morphing materials for soft robotics. For soft composites, I will show how liquid metal droplets […]

ASSET Seminar: Domain Adaptation Under Causally Structured Distribution Shifts, Zachary Lipton (Carnegie Mellon University)

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

Presentation Abstract: Faced with unlabeled data in deployment that is sampled from a different distribution than that which generated the training data, all bets are off. Moreover, while numerous heuristics have been proposed for this vague setting, it remains unclear when any among them are applicable. One way to render these problems identifiable is to […]

Spring 2023 GRASP SFI: Michael Johnson, Philadelphia Robotics Coalition “Building STEM Equity through Robotics”

Levine 307 3330 Walnut Street, Philadelphia, PA, United States

This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom.  ABSTRACT Philadelphia Robotics Coalition founder, and School District of Philadelphia engineering teacher Michael Johnson discusses how Philadelphia public schools are using the competitive FIRST robotics programs to build STEM equity in our city. With the goal to inspire and prepare the next generation of STEM […]

POSTPONED – MSE Seminar: “Additive Manufacturing of Intermetallic: A Designer’s Approach”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Modern materials contain extraordinary levels of complexity, with components spanning a hierarchy of length scales. Designing materials with complex microstructures and demonstrating unique behaviors would be difficult solely using a reductionist approach to materials development.   A powerful utility in this endeavor is using multiple, correlative, and scaffolding computational tools.  This talk focused on using an […]

BE Seminar: “Tissue Architecture Driven by Immune Cells” (John Hickey, Stanford University)

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

"Tissue Architecture Driven by Immune Cells" John has developed multiplexed spatial omics techniques and computational tools to decode critical interactions within the multidimensional data (e.g., multiscale models and deep learning algorithms). He applied these tools to understand spatial relationships of cells within the healthy human intestine, inflammation induced cancers (esophageal cancer), and in T cell […]

PICS/MEAM Seminar: “A Low Rank Tensor Approach for Nonlinear Vlasov Simulations”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

In this work, we present a low-rank tensor approach for approximating solutions to the nonlinear Vlasov equation. Our method takes advantage of the tensor-friendly nature of the differential operators in the Vlasov equation to dynamically and adaptively construct a low-rank solution basis through the discretization of the equation and an SVD-type truncation procedure. We utilize […]
