个人简介

Sean Elliott investigates the connection between biological electron transfer chemistry and function of redox active proteins and enzymes, by using direct electrochemistry and spectroscopy. He joined the Department of Chemistry in 2002, following an EMBO Post-doctoral Fellowship at the University of Oxford. A recipient of the Gitner and Templeton Awards within the College of Arts and Sciences, he was promoted to Associate Professor of Chemistry in 2008.

研究领域

Biological Chemistry/Inorganic Chemistry

The Elliott Group investigates the interplay between biological systems and redox-active species (e.g., metal ions, organic radicals, disulfide bonds, reactive oxygen species). Our emphasis is on the kinetic and thermodynamic basis for catalytic redox chemistry, as well as the molecular impact of metal ions and reactive oxygen species upon cells.
