I am a tenured Associate Professor in the Department of Biostatistics and Medical Informatics and affiliate faculty in the Department of Computer Sciences at the University of Wisconsin-Madison. Previously, I was a postdoctoral fellow at Carnegie Mellon University and earned my Ph.D. in Computer Science from Georgia Tech. My primary research focus is computer vision. I am also interested in the applications of computer vision and machine learning in health research. Specifically, my group develops methods and systems to automatically analyze human activities to improve health outcomes. I am currently a member of the NSF Center CHORUS for resilient cyber-physical systems and the U.S. Army AI Innovations Institute. I am honored to have received the NSF CAREER Award and Google Research Scholar Award. I have served as area chairs for leading vision and learning conferences including CVPR, ICCV, ECCV, NeurIPS, and IJCAI. I have also co-authored papers recognized with best student paper awards at MobiHealth 2014 and IEEE Face and Gesture 2015, and a best demo nominee at ECCV 2020. My work has been featured in MIT Tech Review, WIRED UK, New Scientist, BBC, and Forbes.
