Research Interests

Research Interests

My research interests are centred on the neural and endocrine mechanisms that underpin feeding behaviour, metabolism and reproduction in vertebrates. I am particularly interested in how vertebrates, particularly birds, adjust their behaviour and physiology to environmental seasonality such as changes in photoperiod. I use a comparative, multi-disciplinary, approach that combines and integrates the genetic and molecular to the ecological and behavioural levels of biological organisation. In this way, I aim to gain insight into fundamental mechanisms regulating behaviour and physiology from the perspective of the whole animal. Most recently, my research has involved the use of functional genomic technologies, including DNA microarrays, to identify genes in the brain involved in the control of seasonal reproduction, and I have combined this with neurobiological approaches to characterise and monitor activity of neuroendocrine pathways.
