    Research interest: Number theory

I am currently an associate professor at the Morningside Center of Mathematics, Chinese Academy of Sciences. I am doing research on Number theory, representation theory and arithmetic geometry. I am particularly interested in the mathematical objects studied in the Langlands program.
