Research Interests

Solar energy conversion, in both natural and artificial systems, involves the absorption of a photon that can then lead to a series of energy and electron transfer events. Research in the Anna group focuses on understanding these photoinitiated processes. More specifically we are interested in exploring (1) the interplay of vibrational motion with both electronic energy transfer and electron transfer reactions, and (2) the role the environment plays in these processes. To begin to answer these questions we employ both well-established and novel multidimensional spectroscopic techniques to explore photoinitiated processes in a range of systems, spanning interests in biology, chemistry, and physics.
