I am a 3-year postdoctoral fellow at the IHÉS, part of the ERC grant QUASIFT under Vasily Pestun. I'm interested in mathematical constructions in classical and quantum field theories using derived algebraic geometry. For example, I think about:
- The construction and classification of (not necessarily topological) twists of classical and quantum field theories, especially using techniques of derived algebraic geometry and homotopical algebra.
- The connection between structures appearing in various versions of the geometric Langlands correspondence and twists of four- and five-dimensional supersymmetric gauge theories.
- The theory of factorization algebras as a model for perturbative field theory.
