On Wednesday, August 27, from 5:00 PM to 7:00 PM ET, Venture Lab is hosting the 2025 Entrepreneurship Expo, a one-stop experience for students to explore co-curricular programs, discover entrepreneurship clubs, and learn how to take the next step in their entrepreneurial journey. From students who are curious about innovation to those actively launching ventures, […]
Abstract: Rare earth elements (REEs) are essential for clean energy technologies including batteries for electrical vehicles, wind turbines and LED screens due to their unique magnetic, optical, and electronic properties. Efficient methods for their recovery and separation are urgently needed to meet the growing demands of a rapidly evolving green economy worldwide. However, current separation […]
For decades materials engineers have been inspired by biology to create improved properties, for example nacre-inspired hierarchical structures to improve toughness, tree-inspired vasculature to deliver fluids that can react and heal an interface, and mussel-inspired strong underwater adhesives utilizing cation-pi interactions. Now, the bioengineering toolset has reached a maturity where we can start to employ […]
Geometric and Physics Stucture Preservation in Scientific Machine Learning Nat Trask, Associate Professor in Mechanical Engineering and Applied Mechanics at Penn Engineering, will share about his work constructing real-time digital twins built upon a data-driven finite element exterior calculus; constructing auto-regressive integrators with guaranteed long-term stability independent of rollout length; and constructing data-driven particle models […]
Abstract: In this talk, I will discuss a collection of highlights from our recent work in trustworthy AI. (1) Certifying reasoning explanations with reliability guarantees and aligning with expert knowledge, (2) Simple yet effective steering inspired from theoretical rule-following mechanisms for transformers, and (3) The impossibility of monitoring stateless attackers and what safety defenses should […]
Abstract: First, I will outline our work on overcoming barriers to desert rehabilitation for urban greening, landscaping, and regional food security. In arid regions, freshwater is scarce, sandy soils lose water and fertilizers rapidly, which stifles plant growth. Our team has developed two complementary solutions: (i) Superhydrophobic Sand (SHS)1 — a plastic-free, bio-inspired mulch that […]
On the real line, a random walk that can only move in the positive direction is very unlikely to remain close to its starting point. After a fixed number of steps, the left tail has a Gaussian profile, under minimal assumptions. Remarkably, the same phenomenon occurs when we consider a positive random walk on the […]

What’s the best way to avoid paper retractions and irreproducible results? Conduct rigorous research. Join us for a public talk with Ivan Oransky, Co-Founder of Retraction Watch, Anita Anita Bandrowski, founder of The Research Resource Identification Initiative (RRID), and Jason Williams, Assisant Director of the DNA Learning Center, Cold Spring Harbor Laboratory, on doing science […]
Please join us on Tuesday, September 9 for an overview of research being done in the MEAM Department, hosted by MEAM Department Chair, Dr. Kevin Turner. This is an excellent opportunity for current graduate students to learn about the breadth of work being done in MEAM. The following faculty will be presenting (not in order […]
We present a unified perspective on test-time thinking as a lens for improving generative AI agents through finer-grained reward modeling, data-centric reasoning, and robust alignment. Beginning with GenARM, we introduce an inductive bias for denser, token-level reward modeling that guides generation during decoding, enabling token-level alignment without retraining. While GenARM targets reward design, ThinkLite-VL focuses on the data […]
