Research Interests

Dr Fenwick received his BA and MSci degrees in Experimental and Theoretical Physics from Jesus College, University of Cambridge in 2002. After graduation he worked as a Systems Engineer at BAE SYSTEMS until joining University College London where he completed a PhD (2007) in near-field microscopy and lithography of organic semiconductors. He continued as a postdoctoral researcher at UCL focusing on the development of materials for organic light-emitting diodes (OLEDs) before moving to the Institut de Science et d'Ingénierie Supramoléculaires (I.S.I.S.) at the University of Strasbourg where he won a Marie Curie Intra-European Fellowship to study the functionalization of electrodes for organic field-effect transistors. 

Dr Fenwick started at Queen Mary in 2015 as a Royal Society University Research Fellow and is now Senior Lecturer in Materials Science where his research is focused on materials for organic thermoelectric devices.
