I was born in Kenya, qualified from University of Cape Town, South
Africa, with postgraduate training in Paediatrics in Manchester and
London, United Kingdom. In 1989, as a lecturer at University of Oxford, I
returned to Kilifi in Kenya, to help set up an unit to study severe
malaria in African children. Thereafter I spent two years as a
Post-doctoral fellow at Johns Hopkins, USA; studying mechanisms of brain
damage in central nervous system infections. I completed his training
in Paediatric Neurology at Great Ormond Street Hospital, UK. In 1998 I
was awarded a Wellcome Trust Senior Clinical Fellowship at University
College London, to return to Kilifi, to study central nervous system
infections in children, examining the epidemiology and mechanisms of
neurodevelopmental disorders (e.g. autism) and epilepsy, particularly
brain damage caused by infections and other insults to the brain.
I teach undergraduate and post graduate students child neurodevelopment, neurology and psychiatry, and international health.
I am examining the epidemiology and behavioural consequences of children experiencing a range of adversities in the low-income countries of insults, in particular the association of autism and developmental disorders with infections of the central nervous system (particularly malaria, HIV and bacterial meningitis). I also conduct research on the epidemiology of epilepsy and neurocognitive consequences of sickle cell disease in Africa. This research has led to an interest to the mental health of children from immigrant populations in the UK and Europe. My research in Oxford focuses on autism and neurodevelopmental disorders, particular the causes and consequences of these conditions in this region.
