Research Interests

My current research interests involve both electronic and structural aspects of conducting molecular systems. We employ scanning probe techniques to probe electrical conduction in single molecules. In particular, a close collaboration with Martin Elliott (Physics and Astronomy) and Dafydd D Jones (School of Bioscience) has pioneered conduction measurements through single protein molecules chemically bonded to both meatal surface and tip. Synchrotron-based grazing incidence diffraction is also used to probe the structure of organic conducting films, particularly polymer-fullerene blends for organic photovoltaic cells.


Currently, I am module organiser for:
PX2231 Thermal and Statistical Physics (double module)
PX4119 Large Molecules and Life
I hold weekly first- and second-year tutorials.

I also supervise several 3rd and 4th year project students taking:
PX3315 - Physics Project
PX4310 - Project

Recently taught modules include:
PX2221 Physics Applied
PX2223 Physics of Solids and Soft Matter
PX3109 Solid State Physics

I obtained my first degree in Cardiff in 1980 and my DPhil at Oxford in 1984. Following post-doc positions at Bath and Cardiff, I was appointed to a lectureship at Cardiff in 1988. I have been a Reader in Nanophysics since 2004.

Postgraduate Students

I supervise one post-doc fellow and three research students.
