Department of Mathematics University of California, Los Angeles Mathematical Sciences Building 5242 Address: UCLA Mathematics Department Box 951555 Los Angeles, CA 90095 Email: cyhsu at math.ucla.edu I am a Hedrick Assistant Adjunct Professor at UCLA. My mentor is Romyar Sharifi. I received my PhD from Harvard University in 2019 under the supervision of Barry Mazur. Starting March 1, 2022, I will be a postdoctoral researcher at Laboratoire Paul Painlevé, Université de Lille, working with Mladen Dimitrov as part of the GALF project. In Fall 2023, I will be an Assistant Professor at Santa Clara University.
