Peter Sushko received his BSc and MSc degrees in Physics from St. Petersburg State University, Russia, and his PhD in Physics from the University College London (UCL), UK. After completing his PhD in 2000, he held several research positions at the Department of Physics and Astronomy and the London Centre for Nanotechnology, UCL.

In 2008 he was awarded the Royal Society University Research Fellowship and joined academic staff at UCL; he was promoted to a Reader (Associate Professor with tenure) in 2012. In 2014 he joined PNNL’s Physical Sciences Division as an Associate Division Director with responsibilities for materials science. His research is focused on understanding atomic-scale mechanisms of fundamental processes in complex materials systems and predicting the effects of disorder and defects on materials properties and functions.
