I am a scientist at the University of Bristol. I obtained my Ph.D from Monash University in Melbourne, Australia, and went on to do post-doctoral work at the National Institute of Mental Health in Bethesda, Maryland, U.S.A. My main research interest is in the function of hormones and neurotransmitters, particularly vasopressin (or antidiuretic hormone) which is the hormonal regulator of water homeostasis and has many other effects in the brain (e.g., on social behaviour) and peripheral tissues, and the closely-related hormone oxytocin that is important for mammalian reproduction.
