My research interests lie in the fields of arithmetic geometry and algebraic number theory. Currently I am thinking about arithmetic properties of (supersingular) varieties and Drinfeld modules over finite fields, (local-global principles for) rational points on varieties, anabelian geometry, and Galois representations.
Previously I also worked on (dynamical) Belyi maps, adelic algebraic groups, automorphic representations, and Galois representations attached to abelian varieties.
