Biography
Professional biography
I am a senior lecturer in the School of Mathematics and Statistics.
I studied at Lancaster University, Cambridge University and Kings College London. I subsequently enjoyed a number of research posts at Exeter University, City University London and Imperial College London, before joining the Open University in 2001.
Research interests
My current research interest is in the area of spintronics, and involves the theoretical and computational modelling of magnetic multilayers and other nanostructures.
In particular, I am interested in electronic quantum effects exhibited by spin and charge transport through these structures. This includes magnetic exchange coupling, various types of magneto-resistance behaviour, magnetocrystalline anisotropy and a variety of mechanisms to effect magnetic switching.
Teaching interests
I am currently module team chair for M833, and am chairing the refresh of MST224 and the production of a new module, MST225, for first presentation in 2028.
In the past, I have written course texts for MS324, MS325, MST224, MST125 and MS327 and assessment materials for MST210.
Impact and engagement
My research is in a highly applicable area of mathematics and has contributed to the development of the modern day hard disk. I am particularly interested in the way that electron spin can be used to transmit information and manipulate nanoscopic devices, with application to the real world. An article based on some of my research was recently featured in 'UK Success Stories in Industrial Mathematics', Springer 2016, ISBN-10: 3319254529.
External collaborations
I have enjoyed fruitful collaboratorations with a large number of colleagues in Japan, Brazil, Poland and the UK.
Projects
EPSRC Mathematical Sciences Research Associate Fund
EPSRC Research Associates in Mathematical Sciences have offered £100,000 for research associate positions with the M&S department to start in October 2021.
EPSRC DTP Mathematical Sciences 2020/21
As part of the additional funding for mathematical sciences announced by the Prime Minister on the 27th January, EPSRC on behalf of UKRI would like to offer the Open University an allocation of £146,201 to support doctoral students who must start their studies no later than October 2021. We will provide a single grant to support all the students from this allocation at your institution. The funding needs to be used in line with the UKRI training grant terms and conditions and the additional conditions that are outlined in the letter (see docs tab).
