Broadly, I am interested in the geometric and topological aspects of string theory and quantum field theory.
I am currently studying invariants of links and 3-manifolds, their connections to Chern–Simons theory, and categorical structures in low-dimensional topology. In addition, I am exploring algebraic-geometric aspects of matrix models and the Gromov–Witten theory of P^1.
My previous research has involved topological string theory, Gromov–Witten invariants, gravitational theories, theoretical particle physics, and the Standard Model.
