I am a tenure track associate professor at Shanghai Center for Mathematical Sciences at Fudan University. I am interested in number theory and related topics in representation theory and algebraic geometry. I received my doctoral degree from Penn State under the supervison of Wen-Ching Winnie Li and Ming-Lun Hsieh, then I was a postdoc of Henri Darmon at McGill. All my works can be found on my Arxiv page: https://arxiv.org/a/wang_h_9.html.
