Research Interests
I am an experimentalist interested in the study of electronic and optical properties of semiconductors and semiconductor nanostructures using high-pressures, magnetic-fields, and linear, nonlinear and time resolved infrared spectroscopy. I am a regular user of the Free-Electron Laser, FELIX, in Holland, and I am the coordinator and spokesperson for UK Condensed Matter Physics users there. I am also a Programme Advisory Committee member for the Dresden laser, FELBE. I like "applicable physics" rather than really pure or really applied physics, for example I study how quickly and why electron spins lose their memory (applicable to spintronic devices). I chaired the International Conference on Narrow Gap Semiconductors, here in Guildford in 2007.
Research Collaborations
I have strong research links with the groups of Prof. Carl Pidgeon (my best friend and mentor) at Heriot-Watt University, Prof Gabriel Aeppli at UCL, Prof. Wolfgang Heiss at Uni. Linz, Dr Lesley Cohen at Imperial College London, Dr Tony Krier at Lancaster, Dr Tim Ashley at QinetiQ Ltd and Dr Lex van der Meer at the Free Electron Laser in Utrecht.

Teaching
In the Physics Department I teach level one Data Handling (aka probability and statistics), level two physics laboratory, level three Physics of Stars. On the MSc in Medical Physics I teach Medical Statistics. For EE I teach a component of the MSc module Nanoelectronics and Devices on spintronics.
Departmental Duties
I manage the department's final year projects, and I am the course coordinator for the Physics with Satellite Technology degree pathway. I am an External Examiner for the Physics Department at Heriot-Watt University.
