Research Interests

My research interests lie in light-matter interactions of ultra-thin 2D and other semiconductors integrated with nanocavities for ultrahigh-speed and highly responsive optoelectronic devices, as well as in the controlled crystallization of perovskite and organic materials for electronic and optoelectronic applications. My expertise also includes additive engineering of 3D and 2D perovskites using organic small molecular additives for applications such as resistive memristors, photodetectors, light-emitting diodes, and lasers.
