I am a PhD candidate at Georgia Institute of Technology advised by Raphaël Pestourie. My research is at the intersection of computational physics and nanophotonics, where I develop inverse design frameworks to realize efficient, multifunctional optical devices. I specialize in adjoint-based optimization and the development of custom physics solvers using a variety of numerical methods, including FDTD, FDFD, and FEM. To bridge the gap between high-fidelity simulation and rapid design exploration, I build physics-informed surrogate models that enable the high-speed evaluation and discovery of next-generation metasurfaces, metamaterials, and integrated waveguides.
