My PhD research explores the situational factors which modulate appetitive behaviour in humans. In particular, I'm interested in the means by which uncertainty about reward availability alters the hedonic properties of palatable food and drink rewards, and the implications of these effects for our understanding of behavioural addictions and substance use disorders. 

Elsewhere, I contribute to an ongoing project investigating the neurochemical correlates of impulsive behaviour, with a view to developing improved treatments for conditions characterized by clinically high levels of impulsivity, such as bipolar disorder.
