My research interests concern how animals adapt to and exploit their environments and in the physiological and biochemical mechanisms which constrain or provide opportunities for them to do so. My research program is inter-disciplinary, combining comparative physiology and ecology with lipid biochemistry and metabolism in vertebrates, and integrating laboratory and field studies on fundamental issues of interest to both zoological and medical communities, as and which also have implications for conservation and management of mammal, seabird, and fish populations.
