Biography

Professional biography

I graduated with a degree in Biochemistry from University of Bristol in 1989 and completed a PhD on the role of microglia in multiple sclerosis at the Institute of Neurology (UCL) in 1993. After a series of post-doctoral research positions at the Institute of Neurology, University of Kent and University of Oxford, I joined the Open University in 1999 as a research lecturer and became a senior lecturer in 2005. 

Other roles: LHCS Director of Teaching
