About
I am a reseach scientist at Meta (Reality Labs). I obtained my Ph.D. in Computer Engineering from University of Wisconsin-Madison in 2023 (Advisor: Prof. Umit Y. Ogras). I also work closely with Prof. Yin Li. Prior to UW, I received my B.S. from University of Electronic Science and Technology of China (UESTC). During my Ph.D. study, I work as a research intern on computer vision field at Meta (Reality Labs), TikTok and Ambarella.
My research interests include ML/CV, human activity recognition (HAR), 3D human pose estimation (HPE), multi-modal sensing, NeRF, generative models, and smart healthcare algorithms.
