Research Summary

My research centres around the neural circuitry and neurochemical processes underpinning fundamental learning processes - particularly the function of dopamine transmission in associative formation and incentive mechanisms that drive different forms of Pavlovian conditioned and unconditioned responding.

This research integrates manipulations of neural function and behavioural assays designed to probe the underlying structure of learning and behaviour, allowing us to model aspects of learned behaviour that are observed in psychological disorders such as addiction (e.g. compulsive approach to reward signals), and neurodegenerative diseases such as Parkinson’s (e.g. impaired directive movement).
