PICS Colloquium: “Micro-organism Locomotion in Viscoelastic Fluids”

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia, PA, United States

Speaker: Becca Thomases, Professor of Mathematical Sciences at Smith College Abstract:  Many microorganisms and cells function in complex (non-Newtonian) fluids, which are mixtures of different materials that exhibit both viscous and elastic stresses. For example, mammalian sperm swim through cervical mucus on their journey through the female reproductive tract, and they must penetrate the viscoelastic […]

PICS Colloquium: “Exploring the landscape of model representations” with William Noid

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia, PA, United States

Speaker: William Noid, Professor of Chemistry at Penn State University Abstract: Many studies adopt low-resolution, coarse-grained (CG) models to investigate polymers, proteins, and other soft materials. These studies must first specify the details that are retained in the low-resolution model, i.e., they must specify the “CG representation.” Unfortunately, the “best” representation for complex systems is […]

PICS Colloquium: “Genetic testing and adverse selection” with Eduardo Azevedo

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia, PA, United States

Title: Genetic testing and adverse selection Speaker: Eduardo Azevedo, Professor of Business Economics and Public Policy at Wharton, John M. Bendheim Professor, Thomas L. Bendheim Professor Abstract: Technology is dramatically driving down the cost of sequencing genetic data and increasing the quality of predictions made with this data. A standard concern is that these predictions […]

PICS Colloquium: “Modeling Lone Pair Dynamics in Materials” with Richard Remsing

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia, PA, United States

Title: Modeling Lone Pair Dynamics in Materials Speaker: Richard Remsing, Assistant Professor of Chemistry and Chemical Biology at Rutgers University Abstract: Materials properties are governed by the structure and dynamics of the bonds between their constituent atoms. In addition to covalent, metallic, and ionic interactions that we typically think about, lone pair electrons can result in […]

PICS Colloquium: “Representations Learnt from Synthetic Volumes Enable Training-free Medical Image Analysis” with Neel Dey

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia, PA, United States

Speaker: Neel Dey, Postdoctoral Associate in the Massachusetts Institute of Technology Computer Science and Artificial Intelligence Laboratory Abstract: Current medical image analysis projects involve months to years of data annotation and custom technical development. This talk introduces methods to train networks that generalize out-of-the-box to new modalities, anatomies, and datasets all without retraining for the […]

PICS Colloquium: Motion-based rules and solitary waves: ameloblasts and birds with Brian Cox

Penn Institute for Computational Science 3401 Walnut Street, 5th Floor, Philadelphia, PA, United States

Speaker: Brian Cox earned his Ph. D. in theoretical physics at Monash University in Australia, based on computational solutions to the relativistic Hartree-Fock equation, comprising 1200 lines of code on punch-cards, stored in a cardboard box. His other research interests include: magnetism (Oxford); quantum chemistry (NASA Langley); fracture mechanics, fatigue, crack bridging, textile composites (Rockwell/Teledyne); motion-based […]

PICS Colloquium: Combining High-Throughput Workflows, Quantum Chemistry, and AI for the Discovery of Tunable Materials with Unprecedented Properties with

Penn Institute for Computational Science 3401 Walnut Street, 5th Floor, Philadelphia, PA, United States

Speaker: Andrew Rosen is an Assistant Professor of Chemical and Biological Engineering at Princeton University. His research group leverages recent advances in high-throughput computing, machine learning, and quantum-chemical calculations to predictively design new materials for a more sustainable future. Abstract: The solutions to many of society’s most pressing problems rely on the discovery of materials with […]

PICS Colloquium: Mean flow and turbulence in unsteady urban canopy flows with Marco Giometto

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia, PA, United States

Speaker: Dr. Giometto is an Assistant Professor in the Civil Engineering and Engineering Mechanics department at Columbia University and an Amazon Visiting Academic. He studies both fundamental and applied problems related to fluid dynamics and turbulence, with an emphasis on atmospheric boundary layer processes. He received his Ph.D. in Civil and Environmental Engineering from Braunschweig […]

PICS Colloquium: A geometric model for superfluid helium-4 with Michal Pavelka

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia, PA, United States

Abstract: Superfluid helium is a peculiar liquid. For instance, it stays liquid even at very low temperatures (below 2K), it flows through narrow capillaries without friction, and temperature gradient makes it move even in the absence of pressure gradient. The usual description of superfluid helium-4 relies on the concept of two fluids, a so called […]

PICS Colloquium: Learning to Model the World (and Yourself) from Vision with Vincent Sitzmann

Penn Institute for Computational Science 3401 Walnut Street, 5th Floor, Philadelphia, PA, United States

Abstract: In this talk, I will discuss recent publications from my group that attempt at learning models of the world and the effect of the actions of an agent within that world self-supervised, solely via interaction. In particular, I will discuss the potential and challenges of video generative models as a candidate for such a […]
