I am an Assistant Professor in the Computer and Information Science Department at the University of Pennsylvania. I also hold a secondary appointment in the Electrical and Systems Engineering Department. I received my Ph.D. from MIT, working with Prof. Dina Katabi, and my B.S. from Peking University.
I am fascinated by how signals (e.g., radio and acoustic waves) carry information far beyond what humans can sense, and how these interactions can be transformed into new foundations for machine and human perception. I am interested in modeling and interpreting those signals with machine learning grounded in physics. I also explore multimodal learning across radio, acoustic, visual, and language modalities to exploit their complementary strengths and to build richer and more robust representations of the physical world. Our projects often draw on embedded sensors and systems, signal processing, statistical modeling, and machine learning.
Current topics of interest include:
