I am an Assistant Professor at Dartmouth College.

My research is in number theory and algebraic geometry. I like to think about the Hodge locus in complex geometry and the Tate locus in arithmetic geometry, with applications to geometric problems on Shimura varieties, K3 surfaces, and abelian varieties. I have been interested recently in (mock-) modularity properties of special cycles in Shimura varieties as well as the study of the non-abelian Hodge locus in non-abelian Hodge theory.

My research is supported by NSF grant DMS-2302388.

My CV is available here.
