I study character varieties and other moduli spaces. I am interested in cohomology of those spaces and related combinatorics. In my thesis I computed intersection cohomology of character varieties for punctured Riemann surfaces. I also like to study relations between theoretical physics and mathematics, in particular in the theory of moduli spaces of Higgs bundles.
