Biography

I completed my BA degree in Physics at Fitzwilliam College, Cambridge in 1985 before moving to the University of Dundee, where I studied the electronic properties of the amorphous silicon-carbide alloy system for my Ph.D. In 1990, I took up a post-doctoral position in the Department of Physics and Astronomy at the University of Leicester where I studied the optical and structural properties of amorphous III-V semiconductors. In 1993, I stayed in the same department as a post-doctoral research associate to study magnetic nanoparticles. Following this, I was employed variously in several positions as a research associate or temporary lecturer while continuiung to develop my interests in magnetic nanocomposites and cluster-assembled materials. In 2010 I was appointed as a lecturer in nanoscience before, in 2017, becoming a teaching fellow. Outside Physics, my interests include bird watching, hill walking, good food and wine and (occasionally) malt whisky.

Teaching

In 2017/2018, I teach on the following  modules and courses

  • PA2230 (Condensed Matter) - module leader
  • PA2900 (Laboratory Physics) - module leader
  • PA2602 (Intermediate Astrophysics and Applied Physics) - module leader
  • PA2605 (Intermediate Applied Physics and Space Science) - module leader
  • PA2606 (Intermediate Applied Physics and Modern Physics) - module leader
  • Opt.3635 (Magnetic Materials) - module leader
  • Opt.4621 (Nanostructure) - module leader
  • NS3017 (Molecular Cell Biology and Nanoscience)

I also regularly supervise a number of final year research projects and advanced study projects. 

My departmental administrative duties in 2017/2018 include the overall supervision of Level 1 and Level 2 Core GRePs (Group Research Projects), and the "Head of Laboratories" role.

I have been a member of the Departmental Teaching Committee since 2011, and sat on the College Academic Committee from 2011-2016.

In 2012 I was made a Fellow of the Higher Education Academy.

Research interests

The main focus of my research is on magnetic nanoparticles and nanocomposite materials.

I have more then twenty years of expertise in designing and operating sources that are capable of depositing nanomaterials under controlled and ultra-clean conditions. A high degree of control over the preparation of nanomaterials is an essential part of realising their potential applications; these include magnetic recording, high efficiency electric motors and various biomedical applications.

I am interested in looking at how novel and artificial structures can be engineered into nanoparticles in a controllable way, and how this can used to establish a high degree of control over the magnetism in new cluster-assembled materials. Synchrotron based x-ray techniques play an important part in my research, for probing both atomic structure and also magnetic properties. I am a frequent user at synchrotron sources such as the DIAMOND light source and the ESRF.

I have a long standing interest in EXAFS (extended x-ray absorption fine structure) and am an experienced user in the technique.
