My research focuses on the role of the hypothalamus in the control of energy homeostasis and reproduction. Both of these physiological roles have important implications for human health. I am particularly interested in how the gut senses nutritional status and signals to appetite centres of the brain such as the hypothalamus and brain stem to regulate food intake. I am also interested in how central hypothalamic neuropeptide circuits act to control body weight and reproductive function.
I have won funding from sources including the BBSRC, the MRC, the Technology Strategy Board, the Society for Endocrinology, the British Society for Neuroendocrinology, the British Pharmacological Society and the NC3Rs. I have successfully supervised more than twenty PhD students to completion. I am Director of Postgraduate Studies (Research) for the Department of Medicine, and Admissions Tutor for the Faculty of Medicine with particular responsibility for widening participation.
