Summary:

Studies light-matter interaction at the nanoscale (metasurfaces, thermal emission, plasmonics) and, with Jennifer Choy, has developed metasurface polarizing beamsplitters that enable compact, chip-integrated atomic magnetometers (optically pumped magnetometry) alongside broader work in quantum and topological photonics.
