Professor Donal Bradley CBE FRS 

Donal Bradley is a Visiting Professor in the Department of Physics at Imperial College London.

Professional Career

Donal Bradley graduated from the Imperial College of Science and Technology with a first class BSc and ARCS in Physics in 1983, receiving the Royal Society for the Encouragment of Arts, Manufactures and Commerce Silver Medal and Fellowship (FRSA) as an outstanding graduate of the Royal College of Science.  His postgraduate research was carried out in the Physics and Chemistry of Solids Group at the Cavendish Laboratory in Cambridge where he received his PhD in 1987 for a thesis entitled Spectroscopic Characterisation of the Processible Conjugated Polymers Poly(1,4-diphenylenediphenylvinylene) and Poly(p-phenylenevinylene).  He was subsequently a BP funded Research Associate (1987), the Unilever Research Fellow in Chemical Physics at Corpus Christi College, Cambridge (1987-89), and a Toshiba Fellow within the Chemical Laboratory at the Toshiba R&D Center in Kawasaki, Japan (1987-88). In 1989 he was appointed University Assistant Lecturer in Physics at the Cavendish Laboratory (1989-93) and College Lecturer in Physics and Title A Fellow (1989-93) at Churchill College, Cambridge, subsequently becoming Director of Studies in Physics (1992-93).  In 1993 he moved to a Readership in the Department of Physics at the University of Sheffield, being promoted to Professor in 1995.  During a seven year stay in Sheffield he founded the Molecular Electronic Materials and Devices Group (now led by Professor David Lidzey) and held both the Royal Society Amersham International Senior Research Fellowship (1996-97) and a Leverhulme Research Fellowship (1997-98). He was also Warden of Tapton Hall of Residence (1994-99), and Co-Director (1994-95), then Director (1995-2000) of the Centre for Molecular Materials.  Professor Bradley returned to his Alma Mater as the Professor of Experimental Solid State Physics in 2000 to lead a new strategic initiative on molecular electronic materials and has served as Head of the Experimental Solid State Physics Group (2001-04, 2005) and a Director of Imperial College London Consultants Ltd (2005-06).  He was elected a Fellow of the Royal Society (FRS) in 2004, a Fellow of the Institute of Physics (FInstP) in 2005 and Fellow of the Institute of Engineering and Technology (FIET) in 2013.  He was appointed Head of Department in 2005 and became Lee-Lucas Professor in 2006.  Promotion to Deputy Principal of the Faculty of Natural Sciences followed in 2008 and in 2009 he was appointed as the first Director of the newly established Imperial College London Centre for Plastic Electronics (, one of five UK National Centres of Excellence in the Plastic Electronics sector.  Professor Bradley was awarded a CBE in the 2010 New Years Honours for services to science. In October 2011, he was appointed Pro-Rector (Research), chairing the College's Research Committee and joining the College Management Board. From 1st August 2013, following a reorganisation of the College management structures Professor Bradley became the first Vice-Provost (Research), joining the Provost's Board. He received a DSc (Honoris Causa) from the University of Sheffield in 2014 and was registered as a Chartered Engineer (CEng) in 2015.

In September 2015 Professor Bradley moved to the University of Oxford to become Head of the Division of Mathematical, Physical and Life Sciences (, Professor of Engineering Science and Physics and a Professorial Fellow at Jesus College. He was simultaneously appointed a Visiting Professor in Physics at Imperial College and continues as an external member of the Centre for Plastic Electronics and as part of the Imperial College - Oxford University - Queen Mary London, Plastic Electronics Centre for Doctoral Training's student supervisor team (



Professor Bradley's research focuses on the physics and application of molecular electronic materials and devices, a subject highlighted in successive International Reviews of UK Physics and Materials research as having produced outputs of the highest quality. Professor Bradley's contributions to the subject have led to wide-ranging publications that address both fundamental and more applied topics, and that place him amongst the 1% most highly cited physicists and materials scientists in the world (ISI Highly Cited Scientist). He has an h-index of 99 (m = 3.19), having thus far published some 630 ISI listed publications with  > 49,000 citations (ISI Web of Knowledge). He is a co-inventor of conjugated polymer electroluminescence, co-founder of Cambridge Display Technology Ltd, co-founder and formerly Director of Molecular Vision Ltd, formerly member of C-Change (UK) LLP and currently Director of Solar Press Ltd with more than twenty five patent families to his name.
