Rate My Professor Mike Garratt

Garratt's research focuses on how reproduction influences life-history, health, and ageing, including the physiological effects of gonadal-derived hormones, consequences of mating, impacts of social pheromone perception on life-history trajectories, sexual dimorphism in lifespan, and interventions to improve healthy ageing. He employs molecular-genetic techniques in mice and comparative approaches across species to explore links between reproduction and ageing in wild animals. Key publications include 'Sterilization and contraception increase lifespan across vertebrates' (Nature, 2025), 'Distinct macronutrient ratios optimize offspring survival, growth, and maternal glucose tolerance across mouse reproduction' (PNAS, 2026), 'Prior mating without fertilization increases subsequent litter size in mice' (Biology Letters, 2025), 'Sensory detection of female olfactory cues as a central regulator of energy metabolism and body weight in male mice' (iScience, 2023), and 'Lifespan extension in female mice by early, transient exposure to adult female olfactory cues' (eLife, 2022). With over 2,800 citations on Google Scholar, his contributions advance understanding of reproductive influences on ageing and health.
