Overview
Research summary
I am interested in the role that contextual or environmental cues play in the control of both goal-directed and reflexive behaviours. The contextual control of behaviour has been implicated in a wide variety of situations from drug addiction to the formation of episodic memories. My focus is on the neural and psychological mechanisms underlying the contextual modulation of behaviour, with particular emphasis on the involvement of the prefrontal cortex and hippocampal formation. In addition, I am also interested in how dysfunction to contextual processes may contribute to neuropsychological disorders such as schizophrenia.
