Donal Bradley facts for kids

Donal Donat Conor Bradley CBE FRS FInstP FIET FRSA is the Vice President for Research at King Abdullah University of Science and Technology (KAUST), Saudi Arabia. From 2015 until 2019, he was head of the Mathematical, Physical and Life Sciences Division of the University of Oxford and a Professor of Engineering Science and Physics at Jesus College, Oxford. From 2006 to 2015, he was the Lee-Lucas Professor of Experimental Physics at Imperial College London. He was the founding director of the Centre for Plastic Electronics and served as vice-provost for research at the college.

Bradley is known for his contributions to the development of molecular electronic materials and devices. Plastic or printed electronics, as this technology is widely known, embodies a paradigm shift towards low temperature, solution-based device fabrication with applications in energy efficient displays and lighting, photovoltaic energy generation, medical diagnostics and longer term potential for optical communications.

Education

Bradley was a pupil and latterly Head Boy at the Jesuit Wimbledon College in the London Borough of Merton. He studied as an undergraduate student (BSc Physics) at Imperial College London between 1980 and 1983 and obtained a first class honours degree and Associateship of the Royal College of Science. He was awarded the Royal Society for the Encouragement of Arts, Manufactures and Commerce Silver Medal and fellowship (FRSA) as an outstanding graduate of the Royal College of Science and served in his second year as the Royal College of Science Union Departmental Representative for Physics. His postgraduate research was undertaken in the Physics and Chemistry of Solids Group at the Cavendish Laboratory, University of Cambridge, and he received a PhD in 1987.

Career and research

After completing his PhD in 1987 he was briefly a postdoctoral research associate funded by British Petroleum before being simultaneously awarded the Unilever Research Fellowship in Chemical Physics at Corpus Christi College, Cambridge (held 1987 – 1989), and a Toshiba Research Fellowship to work at the Toshiba Corporation Research and Development Center's Chemical Laboratory in Kawasaki, Japan (held 1987–88).

Upon returning to Corpus Christi College, Cambridge, after a year spent in Japan studying the nonlinear optical properties of poly(arylenevinylene) polymers, he played a central role in the February 1989 discovery of conjugated polymer electroluminescence, suggesting the experiment that led to Jeremy Henley Burroughes' first observation of light emission. Together with Jeremy Burroughes he undertook the initial characterisation of the basic properties of poly(p-phenylenevinylene) light emitting diodes, demonstrating that the light emission phenomenon was injection electroluminescence and that the frequency response was sufficiently fast to permit video display applications. Recognizing the importance of their discovery Bradley and Burroughes decided that it should be patented and together with Richard Friend filed a GB patent (PCT/GB90.00584) with first claim:

An electroluminescent device comprising a semiconductor layer in the form of a thin dense polymer film comprising at least one conjugated polymer;
a first contact layer which is selected so that on application of an electric field to said device charge carriers of a first type are injected into the semiconductor layer; and a second contact layer which is selected so that on application of an electric field to said device charge carriers of a second type are injected into the semiconductor layers, wherein the polymer film of the semiconductor layer has sufficiently low concentration of extrinsic charge carriers that on applying an electric field between the first and second contact layers across the semiconductor layer as to render the second contact layer positive relative to the first contact layer charge carriers of said first and second types are injected into the semiconductor layer and combine to form in the conjugated polymer charge carrier pairs which decay radiatively so that radiation is emitted from the conjugated polymer.

Bradley was the corresponding author for the subsequent 1990 Nature paper reporting the discovery of conjugated polymer electroluminescence. This paper rapidly became the most highly cited paper in the field of molecular electronic materials and devices – a position that it holds to this day – and it triggered an explosion of activity around the world, thereby launching the new field of plastic electronics.

Bradley is an Institute for Scientific Information highly cited author in both Materials Science and Physics with 563 papers published to date. His h-index in January 2019 is 109 and his publications have been cited a combined total of 59,482 times (ISI Web of Science).

Bradley joined the University of Oxford in 2015 as Head of the Mathematical, Physical and Life Sciences Division and Professor of Physics and Engineering Science. He is a Professorial Fellow of Jesus College.

Bradley was one of the 21 members of Oxford congress who stood to oppose the debate on the university's response to a changes proposed to the Universities Superannuation Scheme (USS) in March 2018.

On 7 April 2019 Bradley joined King Abdullah University of Science and Technology (KAUST) as the Vice President for Research.
