Revealing Nature's Designs

Nature has had 2.4 billion years to evolve and engineer excited state dynamics. From photosynthesis to vision to photoenzymes, we examine natural mechanisms to steer excited states. Our goal is to isolate and identify new design principles to control quantum dynamics.

Steering Excited State Dynamics

Electronic excited states carry enough energy to make and break chemical bonds. Photochemistry operates outside the Born-Oppenheimer regime -- thereby escaping our standard chemical intuition. We seek new strategies to steer excited states and to control their reactivity.

Seeing the Unseen

You can't engineer what you can't see. We build new spectroscopic tools to probe femtosecond dynamics of electronic excitations. In living cells, protein complexes, and small molecules, we capture how these systems evolve with unprecedented depth and specificity.
