Research Interests

I have several lines of research currently underway all related to my specific interest in behavioural neuroendocrinology. 

My research focuses on how environmental cues can trigger the expression of functionally important behaviours. This is a question of significant importance in neuroscience, and neuroendocrine behaviour is an ideal model to address this problem. Neuroendocrine-related behaviours are thought to be initiated or enabled by peripheral hormone secretion, and appear to involve specific neurohormonal actions of peptides within the brain. The exact mechanisms by which hormones affect the apparent organisational changes in neuronal circuitry and the specific chemical signals involved in sustaining the resulting behaviours, are questions fundamental to understanding behavioural disorders.
