RESEARCH AREA
Brief Introduction
Our lab is interested in addressing problems of energy, environmental,
and biological relevance for a greener and more sustainable future. Borrowing
inspiration from natures enzymatic reactivity, we aim to combine transition
metal catalysis and light-harvesting techniques to convert earth-abundant
materials into value-added commodity chemicals. Specifically, we seek to develop
generalizable transition metal architectures to conduct challenging redox
transformations (e.g., water oxidation, CO2 reduction, N2
fixation, etc.) via facile proton and electron transfer processes both in the ground
and excited states. Our research program encompasses the synthesis and
characterization of reactive transition metal complexes to correlate their
physical and electronic structure with reactivity.
