Research summary

My research is split into two themes: development of novel computational approaches to electronic structure; and modelling of semiconductor systems using these techniques.  In recent years I have also become interested in apply electronic structure techniques to biological systems.

My main technique is a linear scaling electronic structure technique (CONQUEST) which is capable of calculations with ab initio accuracy on systems containing millions of atoms.  This code has been developed in close collaboration with the National Institute for Materials Science in Japan, in particular with Dr. Tsuyoshi Miyazaki.

I have modelled the growth of silicon, diffusion of hydrogen on silicon, and more recently the structure of bismuth nanowires on silicon.  All these calculations have been carried out in close collaboration with experimental groups in the UK, Geneva and Japan.

I studied Natural Science at Clare College, Cambridge, reading Physics & Theoretical Physics in my final year.  After a year's voluntary work, I spent two years working as a device physicist in a small industrial company specialising in modelling field effect transistors in GaAs.  I then moved to the Department of Materials in Oxford University for my D. Phil.

After a year at Keele University, I moved to UCL in the summer of 1998 as a PDRA. I am now a Royal Society Research Fellow and Reader in Physics, working on electronic structure modelling of semiconductor surfaces, particularly one dimensional structures on these surfaces.  I am also actively engaged in developing new techniques, at the moment looking at accurate modelling of large systems and non-adiabatic effects in conduction of nanostructures.
