The geometry and topology group at USC has wide-ranging interests, with special focuses on symplectic geometry, low-dimensional topology, complex geometry, and homological mirror symmetry. Our research has close connections with algebraic geometry, representation theory, categorification, and dynamical systems, and is motivated in part by string theory and mathematical physics.

The schedule for the current USC topology seminar is available here.
