Thesis « Reactivity of diiron centers ; from enzymes back to minerals »

I am an American geochemist and materials scientist, specializing in the study of redox active materials and their behavior under high pressure and photochemical irradiation.

I am currently working with the CNRS and CiNaM to investigate the reactivity of catalytic minerals, specifically green rusts, under hydrothermal conditions for their implications in the origin of life, environmental remediation, and as a source of bio-inspired green energy. These kind of metastable minerals share analogous atomic coordination with the reaction centers of primative enzymes like (sMMO, CODH, etc). Futher study of these natural catalysts will answer questions on the origins of metabolism with the added benefit of uncovering efficent pathways for bio-inspired carbon capture, sequestration, and utilization (CCUS).

My prior experiments with Rutgers University’s ENIGMA program reconstructed the photochemistry, nutrient recycling, and sequestration of metals in the ancient Earth’s oceans and its implications on the evolution of life.
