Carl is a clinical reader and honorary consultant in neurology.  He graduated in medicine from Cambridge University in 1988, did his early postgraduate medical training in London, Newcastle and Falkirk and then trained in neurology, stroke and epidemiology in Edinburgh.  He spent a year in Melbourne where he specialised in movement disorders before taking up his present post in 2001.  He is married to Gay, a GP, and has one daughter, Helena.  A committed Christian, he would like to have more time to serve in his church and develop his interests in Fairtrade and conservation.

Research Overview

Carl is a consultant neurologist with subspecialty interest in movement disorders.  His main research interests are in evidence-based medicine and broader aspects of clinical epidemiology such as incidence and prognostic studies, particularly in relation to Parkinson's disease, other movement disorders and stroke.  His team have established several cohorts of parkinsonian patients for long-term follow-up and support a number of non-industry sponsored clinical trials and Cochrane reviews, whilst also trying to promote multidisciplinary neurology research in Aberdeen.

Current Research

The PINE study: a population-based incidence cohort of people with Parkinson's disease and other parkinsonian disorders, along with their carers and controls who are being followed up lifelong to establish long-term prognosis.

The Parkinson's Incidence Cohorts Collaboration:  an individual patient data meta-analysis of all population- based incidence cohorts of Parkinson's disease to assess prognosis and allow prognostic modelling.     

The Scottish PSP/CBD prevalence cohort:  a cohort of people with two related Parkinson's plus disorders,  Progressive Supranuclear Palsy and Corticobasal Degeneration as well as Parkinson's disease controls, to assess diagnostic and care pathways and prognosis.
