About
I am a graudate student at department of mathematics, MIT, starting from Fall 2021. My advisor is Wei Zhang. Before that, I was an undergraduate student at deparment of mathematics, Peking University, with advisor Ruochuan Liu
I work in arithmetic geometry and number theory. My interests include integral and rational points on polynomial systems (Diophantine geometry), cohomology and motives over number fields, and the arithmetic applications of the relative Langlands program (e.g., periods, theta correspondences, and duality phenomena).
I am currently on the postdoc job market (Fall 2025).
