My work has focussed mainly on neural substrates of behaviour with a focus on animal models of reward and of psychotherapeutic drug action. Recent studies have revealed novel interactions of specific chemical messengers (including the amino acids glutamate and GABA, and two amines: dopamine and serotonin). The results of such experiments are relevant to gaining a clearer understanding of brain function and to the development of more effective treatments for the psychiatric disorders of depression, schizophrenia and substance abuse. My current research interests, in motivation and reward have moved into the domain of functional brain imaging (fMRI) with human subjects – the focal points of this research are twofold: 

  1. With the CARPI group – neurodevelopmental, targeting differences between “behaviourally high risk” and control populations of children and adolescents.
  2. With the TRANSALC group – studying aspects of mental health and addictions in adults.  My general academic interests include a broad range of biological and psychosocial areas.
