Biography

Roger joined the Department in 1983 as a Research Fellow with the SRC (as it was then - interesting how the EPSRC has gained letters over the years) Surrey Ion Beam Centre. He was employed to look after the computing facilities associated with the research group - a single pdp11, about half of the computer "power" in the department in those days.

Before this he had spent 3 years as a post doc at the Naval Postgraduate School in Monterey California, making Molecular Dynamics Studies and Computer Animations, which is still the main area of his research activities. He did his PhD work in the Electronic & Electrical Engineering Department of the University of Salford, on the Mathematical Modelling of Atomic Collisions in Solids.

He was made a Lecturer in the Department in 1986, promoted to Senior Lecturer in 1993 and then to Reader in 1997, reaching the dizzy heights of Professor of Ion Beam Physics in 2002. He is the current Director of the Surrey Ion Beam Centre.

He has performed research at Penn State College and the Chinese University of Hong Kong

Research interests

Main area of research is the interaction of energetic ion beams with solids.Current research activities include the use of Molecular Dynamics Simulations to predict the behaviour of cluster and molecular impacts on surfaces. As well as the use of more simple Binary Collisions simulations to predict the effects of energetic particle solid interactions, in particular ion implantation profiles in crystalline solids. Cluster and molecular impacts include fullerene impact induced desorption of molecular solids.Other areas of interest are in automation and control of ion beam analysis equipment. This includes software to automate the collection of data from standard analyses using RBS, PIXE, PIGE, NRA and ERD.He must also take some responsibility for the windows interface to the Data Furnace for the automated and rapid analysis of experimental ion scattering data. Developments in the use of MeV ion beams for Secondary Ion Mass Spectrometry (SIMS) is also of current interest.
