Research Interests:

My research interests are the evolutionary physiology and physiological ecology of animals, especially vertebrates. Current goals include (1) incorporating physiological mechanisms into species distribution models and (2) testing the predictions of bioclimatic models with data on physiological performance. Among other things I am interested in macrophysiology (e.g., studying broad scale geographic patterns in physiology), artificial selection and experimental evolution, adaptations of animals to hypoxia and to extreme environments, allometry and the statistics relating to allometric analyses, methods for assessing body condition, and potential trade-offs between immune function, energy metabolism, and other physiological variables. My primary goal in future work is to minimize type III errors (i.e., getting the right answers to the wrong questions) or in other words to pick important questions.
