About Me

I am a third-year Ph.D. student in Intelligent Systems at University of Pittsburgh, advised by Prof. Kayhan Batmanghelich. Prior to that, I received my B.S. degree in Bioinformatics from Southern University of Science and Technology, China, where I did my undergraduate thesis with Prof. Wei Chen.

My research interests lie in self-supervised learning, computer vision and their medical applications.
