Chris Groves graduated with a 1st class honours degree in Electronic Engineering from Sheffield University in 2001. Thereafter he undertook a PhD in avalanche photodiodes at the same University which was sponsored by Bookham Technologies). After a short period of teaching, he changed research field to organic electronics, specifically photovoltaics, by undertaking postdoctoral positions at the Cavendish Laboratory in Cambridge University working on computational modeling, and then at the Department of Chemistry in the University of Washington, Seattle working on scanning probe measurements. He took up a post as Lecturer at Durham University in 2009 and became Senior Lecturer in 2013.
He is author of more than 30 journal articles, reviews, book chapters and news items which have been cited more than 1000 times. He has acted as referee for more than 20 journals, including Science and Nature Materials, as well as numerous national and international grant awarding bodies.
Organic electronic materials are a disruptive technology when compare to their standard, inorganic counterparts. Their potential low cost and scalable manufacture could lead to significantly reduced costs for large-area electronics such as photovoltaics and transistors. Dr Groves research centres around the relationship between the organisation of the organic material (the morphology) and the performance of the eventual device. This involves Monte Carlo simulation of electron trajectories within realistic device settings, as well as developing new measurement techniques centred around 1/f noise to better understand the consequences of complicated transport environments.
