Gray Group Research Profiles


Hematian, Shabnam

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.
