Research Interest

I have broad interests in the areas of differential geometry, geometric topology, geometric group theory and dynamical systems. I am particularly interested in Gromov norm (simplicial volume) and bounded cohomology of non-positively curved spaces. More recently, I study the discrete isometry subgroups (typically infinite volume) of Hadamard manifolds, especially on how the critical exponent interacts with the geometry and topology of the quotient manifold.
