[Research]
I am currently interested in geometrical and topological aspects of String Theory and QFT, Algebraic Geometry, Enumerative Geometry, Mirror Symmetry, Derived Algebraic Geometry.
I have done research in Topological String Theory, Gromov-Witten Invariants, Mirror Symmetry, Gravitational Field Theories, Theoretical Particle Physics and Standard Model.
