Biography

Andrew is Professor of Materials Physics and currently Director of the Institute of Mathematics and Physics. Prior to arriving at Aberystwyth, he worked with Prof. J.O. Williams in Wrexham on the characterisation of wide-gap materials and before this with Prof. K. Horn at the Fritz Haber Institute in Berlin, developing synchrotron radiation methods for the study of surfaces and interfaces. He graduated with a first class degree in physics from the University of Wales Cardiff and obtained his PhD in semiconductor physics under the supervision of Prof. R.H. Williams FRS.

Research Groups

Research Interests

  • Carbon-based Materials:

    Andrew’s principal research interests lie in the science and applications of carbon-based materials such as diamond, graphene, SiC, organic semiconductors and bio-molecules. His research group develops and applies imaging and spectroscopic methods to probe the influence of nano-scale physical, electronic and photonic properties on the functionality of materials and devices.
