MSE Seminar: “Topology and Quantum Matter: From Axions to Spintronics”

Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

The confluence of fundamental symmetries and spin-orbit coupling is known to produce emergent electronic states in crystalline solids that are accurately described using the language of topology. This talk provides an overview of this relatively young field of research, showing how the synthesis and study of topological quantum matter yields a playground for both exotic […]

Tedori-Callinan Lecture: “Isogeometric Analysis”

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

The vision of Isogeometric Analysis was first presented in a paper published October 1, 2005 .  Since then it has become a focus of research within both the fields of Finite Element Analysis (FEA) and Computer Aided Design (CAD) and is rapidly becoming a mainstream analysis methodology and a new paradigm for geometric design .  […]

ESE Seminar: “AI and Intelligent IC/Accelerator Design: A Synergistic Approach”

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

The recent artificial intelligence (AI) boom has been largely driven by three confluence forces: algorithms, big data, and computing power enabled by modern integrated circuits (ICs) including specialized AI accelerators. In this talk, I will present a synergistic approach on AI and intelligent IC/accelerator designs with two main themes, AI for IC and IC for […]

ESE Faculty Hosted Talk: “Deep Learned Optical Multiplexing for Microscopy”

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

Abstract: Fourier ptychographic microscopy is a technique that achieves a high space-bandwidth product, i.e. high resolution and high field-of-view. In Fourier ptychographic microscopy, variable illumination patterns are used to collect multiple low-resolution images. These low-resolution images are then computationally combined to create an image with resolution exceeding that of any single image from the microscope. […]

CBE Seminar: “Thermodynamics of Sequence-defined Polyelectrolyte Complexes”

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

Abstract: Charged polymers known as polyelectrolytes have been studied for decades, however, understanding their physical properties remains a persistent challenge for polymer scientists. This difficulty stems from the intricate interplay between length scales spanning as much as 3-4 orders of magnitude, which has stymied our understanding of a truly important class of polymers; polyelectrolytes are […]

Thriving in a Start-Up Ecosystem: Success and Failure in the Life of an Entrepreneur

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

We invite you to join an exclusive event with Penn Engineering alumni who will share their stories on how they have thrived in the startup ecosystem. These alums range from an angel investor in Uber, a serial biotech entrepreneur with several exits, an entrepreneur who has generated over half a billion in licensing deals and […]

MSE Seminar: “A Polymer Brush Approach to Controlling Biological Binding to Surfaces”

Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

Polymer brushes are a common feature in many biological surfaces. The ability to rapidly transform a substrate from a hard, structural material to a soft, hydrogel structure over the course of a few tens of nanometers makes polymer brushes elegant materials for tailoring the biology-materials interface. Polymer brushes, because of their surface confinement, are typically […]

BE Seminar: “Developing neuroengineering solutions of biomedical relevance using crayfish as a model system”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

In my talk, I will first describe one of the main projects in my lab that investigates the underlying cellular-molecular mechanisms for changes in alcohol sensitivity of crayfish with different prior social experiences. In this context, I will explain why “simple” invertebrates may provide unique advantages for studying complex phenomena such as socially-dependent drug effects. […]

CIS Seminar: “A Geometric Perspective on Computing Motion”

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

Abstract: The connections between geometry and mechanics have been explored for centuries. How these connections shape computation is a question we are just beginning to explore.  If computers can predict how materials move and deform, they can help us to understand, anticipate and manipulate the physical world. Our group develops models and algorithms that capture the characteristic behavior […]

PICS Colloquium: Concurrent Atomistic-Continuum Modeling and Simulation of Transport Processes in Crystalline Materials

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

Abstract: In this talk we present a concurrent atomistic-continuum (CAC) method for modeling and simulation of transport processes in crystalline materials. The CAC formulation extends the Irving-Kirkwood procedure for deriving transport equations and fluxes for homogenized molecular systems to that for polyatomic crystalline materials by employing a concurrent two- level structural description of crystals. A multiscale […]
