Professor of Physics and Director of the Organic Semiconductor Centre, University of St Andrews, Scotland. Founder of Ambicare Health Ltd. Regional/Associate editor of Journal of Photonics for Energy, and Synthetic Metals. Fellow of the Royal Society of Edinburgh, SPIE, the Institute of Physics and the Royal Society of Chemistry. I lead a research group exploring the physics of organic semiconductor materials and devices - such as organic light-emitting diodes, solar cells and lasers. The group has particular expertise in photophysics including time resolved luminescence from femtosecond to microsecond timescales and its application to the development of advanced materials such as dendrimers and star-shaped truxenes. In addition I explore emerging applications of organic semiconductors, such as explosive sensing and skin cancer treatment. The work of the centre has been recognised through awards such as the Beilby Medal (Insitute of Materials, Royal Society of Chemistry and Society of the Chemical Industry), the Ben Sturgeon Award (Society for Information Display) and the academic R&D award (from idtechex at Printed Electronics USA). I am co-chair of the Organic Photonics and Electronics symposium at the annual Optics and Photonics meeting in San Diego and on the program committees for several SPIE conferences.
