I am now a faculty member at the Moringside Center of Mathematics, AMSS, Chinese Academy of Sciences. I am working on arithmetic algebraic geometry, and particularly interested in p-divisible groups, p-adic Hodge theory, p-adic modular forms, and the geometry of Shimura varieties in characteristic p. Here is my CV.
