Dr Geraint Lewis

Head of Medical Physics Department, Velindre Cancer Centre, Velindre NHS Trust, Cardiff & Honorary Senior Research Fellow, Cardiff University Institute of Medical Engineering & Medical Physics.

Geraint originally from Gwent, completed his B.Sc. degree in Physics at Birmingham University in 1981 and D.Phil. in Nuclear Physics in Oxford in 1985. He then undertook a MRC/CRC post-doctoral research fellowship (involving the development of megavoltage imaging systems for radiotherapy verification) at the Institute of Cancer Research and Royal Marsden Hospital in Surrey (1985-88). After a spell in industry as an applications software engineer with BP (1988-91) he returned to Wales to take up a Wellcome Trust Research Fellowship in Medical Physics at Swansea University, involving the development of x-ray fluorescence and neutron activation techniques for in-vivo elemental analysis (1991-94). During his time at Swansea he developed his research interests in the development of Monte Carlo based computational simulation techniques for modelling radiation transport. Since joining the Medical Physics Department at Velindre in 1994 he has supervised several PhD projects in various aspects of Monte Carlo based dose computation for radiotherapy. In recent years Geraint and collaborators at Velindre have developed their interest in the application of ‘Grid Computing’ techniques for high accuracy dose computations for radiotherapy.
