Research

I work in algebraic geometry and number theory. Currently, I am using tools from the transcendental aspect of algebraic geometry (mixed Hodge modules) and ideas from geometric representation theory to approach questions in singularities of hypersurfaces.

In particular, I am interested in the Strong Monodromy Conjecture, which predicts a mysterious relationship between the discrete invariants of the singularity (poles of the p-adic zeta function) with the differentiable counterparts (roots of the Bernstein-Sato polynomial).

I am also interested in the Riemann-Schottky problem via singularities of theta divisors, where the theory of higher multiplier ideals, developed with Christian Schnell, is designed for this purpose.
