George Doucas was, until his retirement, a Research Lecturer in the Department of Physics, University of Oxford. His research interests were centred on the physics and applications of particle accelerators and particle beams, with particular emphasis on the development of suitable techniques for the determination of the properties of a particle beam. Apart from these areas, he has also worked on the Sudbury Neutrino Observatory (SNO) project as a member of the Oxford team. He is the author of numerous papers on these topics.
