Research interests

My research interests lie in the field of arithmetic geometry. Currently I am thinking about arithmetic properties of (supersingular) varieties and Drinfeld modules over finite fields and their moduli spaces, (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.

Keywords: Arithmetic geometry of varieties over finite fields, local-global principles, rational points, Galois representations, algebraic groups, anabelian geometry, arithmetic curves, zeta functions, Neukirch-Uchida theory, abelian varieties.
