My research focuses on the intersection of nanophotonics, condensed matter physics, electrodynamics, and quantum optics. I primarily conduct theoretical and computational studies of multilayer systems composed of dielectrics, metals, and embedded atoms. The goal is to understand and control their tunable optical properties, enabling the manipulation of non-classical light–matter interactions.
