The Engel Group chooses problems at the interface of theory and experiment where we can test our understanding of excited state dynamics. We look for new design principles to control chemical reactivity, and we often find our inspiration in biological systems. We create new spectrometers of our own design to reveal new dynamics and new organizing principles for steering chemical reactivity. We approach our problems through a careful balance of synthesis, spectroscopy, theory, and biophysics.
