Organisation profile
Research in the energetics group covers areas affected by the phenomena of energy expenditure and energy balance. Research in obesity, ageing, limits on sustained energy expenditure, and quantification of free-living energy demands are active areas of research. Work in the energetics of flight and bat biology are areas that are now largely completed.
