Using photo physical tools our group we understand excited state processes to solve mechanistic puzzles, unravel new reactivity, develop new chemical paradigms from excited states and develop new systems that are responsive to light. Our group pursues  both steady state and time resolved techniques to address research challenges that originate from excited state reactivity.
