Research interests

I am interested in Algebraic Geometry and the study of Algebraic and Analytical Singularities. My research centers around the interaction between the birational study of singularities and the D-module theoretic approach. In this context, I am mainly focused on the theory of Bernstein-Sato polynomials and related invariants such as multiplier/Hodge ideals, jumping numbers, the complex zeta funtion, the Gauss-Manin connection and the theory of V-filtrations.
