I am an MD/PhD candidate and Gates Cambridge scholar.
The brain chemical serotonin is implicated in a wide range of affective and behavioural processes and is a key drug target in numerous psychiatric disorders, however its exact role is not well understood. Characterising its function more precisely is therefore an important scientific endeavour. I investigate the contribution of serotonin in three domains: emotional memory, behavioural flexibility, and processing social information. I have a particular interest in obsessive-compulsive disorder (OCD) as well as memory reconsolidation.
