Research

Mathematical Interests

Broad interests in Contact and Symplectic topology, and interactions: Symplectic Field Theory and related Floer theories (and polyfolds if need calls), holomorphic curves and foliations, approximately and honestly holomorphic geometry, geometric structures in Hamiltonian dynamical systems and celestial mechanics, global analysis, and low-dimensional topology, but all with a biased view towards pushing techniques to higher-dimensions. Further interests in mathematical physics, Quantum Field Theory, String Theory and Quantum Mechanics.
