Research interests

Our research is interested in how reproduction influences life-history, health and ageing. This includes physiological effects of gonadal-derived hormones, consequences of mating, and how detection of pheromones by the olfactory system influences life-history trajectory. A related research theme explores how sex-specific aspects of reproduction cause sexual-dimorphism in lifespan, and influence the effectiveness of interventions developed to improve healthy ageing.

Within the CNE we are interested in how the brain signals to influence health, ageing and fertility systemically. We are particularly interested in how sex-hormones and cues regarding reproduction help the body prepare for effective reproduction, and how these changes impinge on metabolism and can lead to disease.

Clinical conditions
