Research interests:

Our research group is focused on gaining a better theoretical understanding of the fundamentals of photochemistry. We develop classical and quantum computing techniques to simulate and predict photochemical reactions. In particular, we study internal conversion and nonadiabatic dynamics, which allow a molecule to undergo non-radiative transitions between electronic states by transferring energy to molecular vibrations. Our research has potential applications in light harvesting, energy conversion, and synthesis.
