Shabnam Hematian
Postdoctoral Scholar in Chemistry

B.S., National University of Iran
M.S., Sharif University of Technology
Ph.D., Johns Hopkins University

My research interests include metal-mediated small molecule activation and using bioinorganic and materials chemistry to address fundamental challenges in biological and energy sciences including catalysis, sustainability, and renewable energy. I received my Ph.D. degree with Professor Ken Karlin from Johns Hopkins University. My graduate work was focused on investigating reactions involving synthetic heme/Cu assemblies and nitrogen oxides, particularly nitric oxide (NO), nitrite (NO2-) and hyponitrite (N2O22-).

After my Ph.D., I worked with Professor Jonas Peters in the Joint Center for Artificial Photosynthesis on the electrochemical reduction of carbon dioxide (CO2) to carbon-based fuels. I am currently a postdoctoral fellow at Caltech in the laboratory of Professor Harry Gray where I have been since March 2017. My work in the Gray group focuses on a mechanistic study of multicopper oxidases (MCOs), specifically laccases that couple oxidation of a wide spectrum of substrates such as lignin to the four-electron reduction of dioxygen (O2) to water. These enzymes are of particular interest in biomass degradation for renewable and sustainable production of fuels and chemicals.
