Research

Dr Alexander Peskin graduated from Moscow State University and received his PhD and DSc (Habilitation) from the Russian Academy of Sciences. He worked as an Eleanor Roosevelt Fellow of the International Union Against Cancer at the Swiss Institute for Cancer Research (Cerutti lab) and as a Visiting Scientist at Lodz University (Bartosz lab), before joining the Centre for Free Radical Research in 1998.

Dr Peskin’s expertise lies in biochemistry and enzymology, with a particular interest in thiol biochemistry. His original research focussed on superoxide dismutase and cancer, and the biochemistry of chloramines, and more recently he has been investigating the complex biochemical properties of the peroxiredoxins.
