I am a graduate student researcher at the UCSD Center for Computational Mathematics. My research focuses on structure-preserving and variational discretizations of field theories arising in physics, such as Lagrangian and Hamiltonian PDEs, with applications to mathematical and theoretical physics. My research is supported by the NSF Graduate Research Fellowship DGE-2038238, by NSF under grants DMS-1411792, DMS-1813635, and by the ARCS Scholar Fellowship.
