I have done research in combinatorial and geometric group theory. In particular, I have worked on commensurability classification of right-angled Artin groups and of Baumslag-Solitar groups, Hanna Neumann type bounds for the intersection of subgroups in groups acting on trees, computing intersection of subgroups in some right-angled Artin groups, and the isomorphism problem for submonoids of virtually free groups.
