Special location for this talk: 105 Amy Gutmann Hall Recent advances in Artificial Intelligence are powering revolutionary interactive tools that will transform the very nature of the scientific enterprise. We describe several large-scale projects at the Allen Institute for AI aimed at developing open models, agentic platforms, and novel interaction paradigms in order to amplify […]
The United States recycles less than 9% of plastic waste, representing a tremendous environmental catastrophe and a loss of embodied value. This dissertation presents the structure-property relationships of functional polymers made from an upcycling approach targeting polyolefins for polymer-to-polymer conversions. The overall strategy proceeds by first dehydrogenating polyolefins, then functionalizing the resulting C=C to generate […]
This will be a hybrid event with in-person attendance in Levine 512 and virtual attendance on Zoom. This seminar will NOT be recorded. ABSTRACT Dynamic scene reconstruction from monocular cameras often requires us to simultaneously estimate depth and 3D motion, where knowledge of either one would help to constrain the other. I will review two […]
Future emerging applications like extreme environment electronics, high-performance computing, space sensing, and brain-machine interfaces share a critical goal: massive bandwidth and deployment scalability. To this end, my research group is investigating energy-efficient and scalable sensing and communication techniques, emphasizing circuits, advanced packaging, and signal processing innovations for the above applications. To begin with, I will […]
Advances in engineering have enabled a new generation of soft medical robots and devices with unique theranostic capabilities for interfacing with delicate organs. However, challenges remain in achieving spatial and temporal precision in extreme body environments, particularly within the digestive system. This talk will highlight three recent preclinical innovations addressing these challenges: (i) BIOSENTER: a […]
Abstract: Extracting insights from imaging data used to be straightforward: every component of imaging systems was engineered by humans, the analysis and interpretation of the collected data was driven by human understanding and experience, and only humans were responsible for the impact of the decisions stemming from such insights. Today, however, machine learning permeates every […]
This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. ABSTRACT It was not long after Theodore Maiman published the first demonstration of the ruby laser in the August 6, 1960 issue of Nature1 that it was realized that such a unique light source could be used in many applications, including […]
Abstract: MXenes, a versatile family of 2D materials, have garnered interest for applications in sensing technologies due to their unique combination of conductivity, hydrophilicity, and surface tunability. This talk explores the integration of MXenes into sensor platforms, and discusses their potential in electrochemical, optical, and environmental sensing. Their surface functional groups can be leveraged for […]
Soft biological systems exhibit intricate hierarchical organization, with structures spanning multiple length scales, from tissues to cells and molecules. This structural complexity gives rise to rich mechanical behaviors that profoundly influence biological function. My research integrates soft matter physics and biology to establish a unified framework that connects structure, mechanics, and function in soft biological […]
Zoom link https://upenn.zoom.us/j/98220304722 Abstract We present computational tools for analyzing and designing first-order methods in parametric convex optimization. These methods are popular for their low per-iteration cost and warm-starting capabilities. However, precisely quantifying the number of iterations required to compute high-quality solutions remains a key challenge, especially in real-time applications. First, we introduce a […]
We have made exciting progress in AI by massive models on massive amounts of data center compute. However, the demands for AI are rapidly expanding. I identify how to maximize performance under any compute constraint, expanding the Pareto frontier of AI capabilities. This talk builds up to an efficient language model architecture that expands […]
