I am currently a Ph.D student in Department of Computer Science at UNC at Chapel Hill, advised by Prof. Gedas Bertasius. My current research interests lie in computer vision. Specifically, I'm interested in video understanding, efficiency of video models and multi-modality.

Prior to joining Gedas's Group, I worked with Prof. Dinggang Shen and Prof. Pew-Thian Yap at UNC on medical imaging. I obtained both my B.S. degree in Information Security in 2016 and M.S. degree in ECE in 2019 at Shanghai JiaoTong University. During my M.S. study, I worked with Prof. Shilin Wang.
