Research Interests: I'm interested in group actions and orbifolds in symplectic geometry and algebraic geometry. My PhD thesis was about Chen-Ruan cohomology of symmetric products of orbifolds. Since then, I have been working on torus actions on orbifolds: GKM theory for orbifolds, Cohomology of Toric Orbifolds and Moment Angle Complexes. Recently I worked on weighted Grassmannians and its Schubert calculus.
