My research interests are to understand how the environment controls life processes and how living organisms have evolved to respond to environmental pressure. There are currently three main avenues in which I am addressing these issues: digestive physiology and air breathing in loricariid catfishes of the genus Panaque that use wood in their diet; determinants of variance in exercise performance and hypoxia tolerance in marine fishes and the relevance of swimming and hypoxia tolerance to predicting success in a changing ocean; and the effects of urbanization on exercise performance and thermal tolerance of a small stream cyprinid.
