RESEARCH: Geometry & Topology Group

The geometry/topology group at USC currently has an emphasis on the topology and geometry of low-dimensional manifolds and on contact and symplectic geometry.  This includes Floer homology theories, hyperbolic geometry, mapping class groups of surfaces, quantum invariants and topological quantum field theories. Our research has connections with and is motivated in part by string theory and mathematical physics.
