My interests lie in small animal energetics.
I conducted my PhD on the energy cost of bird flight using 13C labelled bicarbonate. I measured the energy demands of flight in zebra finches, sunbirds, starlings and cockatiels. Major findings were that the flights costs when carrying loads were much lower than expected.
- I am now examining the effects of caloric restriction on energy expenditure and appetite signals in mice. The majority of this work has been to determine if body mass is controlled by a regulatory feedback system and what drives this system.
- I have conducted several studies (i) looking at gorging in mice and its effect on weight loss caused by the initiation of energy compensation mechanisms and (ii) quantifying stress in laboratory rodents using non-invasive detection of steroid products in faeces.
- My most recent studies involve analysing blood samples to assess the levels of circulatory hormones related to appetite and satiety in humans with eating disorders.
- I am also examining whether limits to sustained energy intake at peak lactation are imposed by the capacity of the animal to dissipate body heat. This work is conducted on bank voles (Clethrionomys glareolus), a small wild animal with low litter size.
