Professional biography

I am a senior lecturer in the School of Mathematics and Statistics and currently head of school. 

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, induced magnetic moment, various types of magneto-resistance behaviour, and magnetocrystalline anisotropy.

Teaching interests

In addition to my head of school duties, I am currently module team chair for M833.

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.

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).
