My lab uses functional neuroimaging to investigate the neural basis of dysregulated motivation and control in eating disorders and their treatment. To that end, we collaborate with a number of UK-based and international clinical research groups. More recently, we've begun exploring the neural basis for the therapeutic benefit achieved by transcranial magnetic stimulation and exposure therapy in Anorexia Nervosa, psychological treatments to improve hypoglycaemic awareness in diabetes and gastric bypass surgery in obesity disorders. I carried out the first functional magnetic resonance imaging (fMRI) investigations of amphetamine sensitisation, a drug-based model of dopamine dysregulation, in humans during my PhD and have continued my interest in both pharmacological imaging and psychosis. Beyond this, I am the module leader for MSc Neuroscience: Neuroimaging (B5) module. I am also a member of the Neuroscience MPhil/PhD Sub-Committee.
