Surface electrochemical actuators (SEAs) harness ion-induced surface stress changes to produce large bending deformations at the microscale. They have previously been applied in microrobot locomotion and microbattery validation, demonstrating their […]
Understanding the physical processes modulating the transport of scalars, such as heat, over very rough surfaces is essential for understanding the thermal environment of cities, how wind and solar farms […]
There has been considerable interest in the colloidal self-assembly of photonic crystals with a diamond structure, owing to their exceptional optical properties, such as a wide photonic bandgap and relative […]
Abstract: Liquid–liquid phase separation is a fundamental thermodynamic process that governs structure and function in biological systems, chemical separations, and multiphase materials. Within this broad field, computational studies play a […]
Large language models (LLMs) are powerful but not yet reliable: they hallucinate, misalign with human values, and struggle with social reasoning. In this talk, I will trace a path from […]

This presenter is one of the winners of the 2025 GRASP vote for internal PhD or postdoc SFI Speakers! This is a hybrid event with in-person attendance in Levine 307 […]
Abstract: Beyond lithium-ion batteries, like sodium and potassium, are more abundant in the Earth’s crust and alleviate geopolitical concerns surrounding the materials inside of lithium-based batteries. However, both sodium and […]
The inaugural Penn AI Symposium is a landmark event that gathers leading thinkers who will share their explorations at the frontiers of artificial intelligence. The symposium is hosted by Penn AI, […]
Now in its sixth year, Climate Week at Penn offers opportunities for every member of the Penn community to learn about and act on the climate crisis. The theme for […]
Artificial intelligence systems powered by deep neural networks have achieved remarkable success across a broad range of applications. However, perturbations such as natural image corruptions or crafted malicious queries, can […]
