Staff Profile

Introduction

I am currently the Director of Physics. I did my BSc in Theoretical Physics at Essex University where I was a student parent. I stayed on for my PhD in Laser plasma interactions via computer simulation. I moved into semiconductor physics in 2000 working with Profs Naci Balkan & Mike Adams and since 2004 I have collaborated with Prof Brian Ridley FRS.

I am a member of the Institute of Physics and I'm on the committee of the North East Branch.

I was recently elected to the Professional development and accreditation committee of the IOP and I also sit on the Higher Education, Semiconductor & History of Physics groups.

Current Roles

Director of Physics

Member of School Executive Board for Mathematics, Statistics & Physics.

Previous Positions

2017 - 2020 DPD Physics

2016-2017 Reader and Head of Physics & Astrophysics, Hull University

2013-2016 Senior Lecturer, Hull University

2008-2013 Lecturer, Hull University

My broad research area is semiconductors and devices with a particular emphasis on phonons and high field transport. I have an in-house developed bulk Monte-Carlo transport simulation code which includes non-equilibrium phonons. I've been interested in Gallium Nitride since 2005 for high frequency emission e.g. THz. 

Recent interests include ultra-wide bandgap materials e.g. diamond and cBN.

Research Grants

I was funded by the Office of Naval research sponsored by Dr Paul Maki under grant Nos N00014-15-1-2193 & N00014-18-1-2463 "Theory of transport in Semiconductors"
