About
My research area is arithmetic geometry. I am especially interested in the geometry of cycles on Shimura varieties,
their relations with automorphic representations and orbital integrals, their modularity properties when assembled into arithmetic
theta series (Kudla program), and algebraic aspects of their intersection theory. (My CV ↗)
