I am Professor of Neurology and Genomic Medicine at Imperial College London, and Honorary Consultant Neurologist at Imperial College Healthcare NHS Trust.

My undergraduate training was in London and Oxford. My post-graduate and specialist medical training was in London and Perth (Western Australia). 

My research group focuses on the systems-level integration of genetic, epigenetic, genomic and phenotypic data to identify cell-type specific causal functional pathways underlying complex human behavioral traits and brain disease.

Using gene regulatory approaches and causal inference methods, disease-associated functional pathways and cell-type specific gene expression profiles are then targeted to identify novel therapeutic strategies which cannot be captured using traditional reductionist strategies. 

My research is funded by the MRC, UCB, Roche, the NIHR Biomedical Research Centers Scheme, the EU FP7 Framework and the Brain Tumour Research Campaign (

My clinical activity is in general neurology and epilepsy with a particular focus on the autoimmune and tumor-associated epilepsies. I am a core member of the Imperial College Healthcare neuro-oncology multidisciplinary team. 

I am a member of the International League Against Epilepsy (ILAE) Task Force on Epigenetics, and the Epi4K, Epi25K, EpiPGx and EPITARGET international consortia for epilepsy research. I am on Epilepsy Action's Scientific Awards Panel. I am an Advisor to the Commonwealth Scholarship Commission, the UK Parliamentary Health Ombudsman and Motorsport UK (MSUK). 

Professional Memberships:

Fellow of the Royal College of Physicians (FRCP)
Fellow of the Royal Australasian College of Physicians (FRACP)
Fellow of the Royal Society of Medicine
Member of the Association of British Neurologists
Member of the British Medical Association
Member of the International League Against Epilepsy (ILAE)
