Profile

I have over 20 years of experience in innovative course development and HE teaching. I am a Senior Fellow of the Higher Education Academy and a University of Leicester Distinguished Teaching Fellow.

I graduated from the University of Leicester in 1995 with a first class BSc degree in Physics, winning the departmental prize for best student in both my second and third years. I then stayed on at Leicester to study for a PhD in Many-electron effects in the X-ray absorption fine structure under the supervision of Dr S. J. Gurman. From 1999 to 2006 I was employed as a post-doctoral research associate and temporary lecturer in the department, first working on self-assembled semiconductor quantum dots then on carbon nanotube quantum dots. I was awarded a lectureship in 2006, working on graphene and on abinitio electronic structure calculations focussed on compound semiconductors.

Over time, my career has progressed into teaching leadership within both the School and the wider University. I am currently the Director of Education in the School of Physics and Astronomy and the Deputy Dean of Education for the College of Science and Engineering.

Research

My research interests are focused mainly on the quantum theory of semiconductor nanostructures. I have long standing interests in quantum dots, carbon nanotubes, graphene, scanning tunnelling microscopy of single dopants, and x-ray absorption spectroscopy. I am also interested in compound semiconductor detectors. I am experienced with effective mass, tight-binding, and ab-initio DFT electronic structure calculations for a variety of different systems. I have over 25 years experience of code development and in X-ray absorption spectroscopy.

Supervision

I have successfully supervised 4 PhD students to completion.

Teaching

During over 20 years in HE I have taught most core physics subjects at undergraduate level focussing on mathematical physics, quantum mechanics, and computer programming. I have developed new programmes and new modules. I have a strong interests in programme design, and in developing student skills through authentic assessment.

I am particularly proud of the developments I have made to 'Physics Special Topics'. This is a year 4 module where students act as authors, referees, and editors for their own student-led research journal. I took over the leadership of this module in 2010.

I was the Senior Tutor in the School from 2015-2022 and careers tutor from 2014-2022. From 2009 to 2014 I was the Head of Admissions in the department and the Deputy Admissions Tutor from 2006-2009.

In July 2013 I was awarded a University of Leicester Teaching Fellowship for my 'proactive empathetic and innovative contributions to the teaching and student support activities of the Department of Physics and Astronomy.' In October 2017 I was made a Senior Fellow of the Higher Education Academy (UKPSF 3). In 2018 I was formally commended by the Leicester Learning Institute in recognition of ""the quality of my application for HEA fellowship"". In 2020 I moved from a Teaching and Research contract to a Teaching Focussed contract.
