A long-term interest is in paleophysiology. Years ago I worked with C. Richard Tracy and J. Scott Turner on a biophysical analysis of heat transfer in sailed pelycosaurs (Dimetrodon). More recently Peter Ward and I have looked that the physiological and biogeographic consequences of changes in oxygen levels over the Phanerozoic. We also used a similar approach to evaluate how hypothetical "paleomountaineers" would have done on Mt. Everest over the Phanerozoic.
