#### Research Interests

My research focuses on geometric and topological properties of infinite groups. I am particularly interested in mapping class groups of surfaces, automorphism groups of free groups, and lattices in semisimple Lie groups. These groups lie at the juncture of a tremendous number of different areas of research and can be studied using a wide range of tools. My past work has used ideas and techniques from geometric group theory, algebraic topology, hyperbolic geometry, combinatorial group theory, number theory, algebraic geometry, and representation theory.
