Interests

I am psychiatry SpR and a Clinical Research Associate working with Prof. Paul Fletcher. I work on brain reward systems using pharmacological fMRI and behavioural measures, to study the role of environmental influences and opioid and dopaminergic systems in controlling food reward processing and eating behaviour. In collaboration with GSK, we have recently completed a proof of concept study of a novel mu-opioid antagonist. My current work involves the use of pharmacological fMRI to study the role of the dopaminergic system in food reward processing in healthy controls. This work has a particular focus on the effect of the atypical antipsychotics as such drugs cause significant weight gain with serious consequences for patient compliance and general health.
