Light-based innovation for the biosciences

Prof. Samuel studied for both his MA and PhD in Physics at Cambridge where he developed his interest in time-resolved fluorescence and light-emitting materials. After finishing his PhD he moved to Paris and worked with France Telecom for two years, investigating the non-linear optical properties of organic materials. Then he returned to Cambridge for a year, received a Royal Society University Research Fellowship and took up a position at the University of Durham until  August 2000 when he moved to St Andrews. In 2001 he started the Organic Semiconductor Centre to encourage collaboration between physicists and chemists in developing the next generation of organic semiconductors and their applications in medicine, sensing and communications. In collaboration with the Photobiology Unit at Ninewells Hospital he pioneered the development of ambulatory light sources for photodynamic therapy (PDT) of skin cancer, and is now exploring antimicrobial uses of PDT. He has also developed organic optoelectronic biosensors including a wearable muscle contraction sensor.

Research areas:
