My interests in biology span from morphology to physiology and ecology. Of particular and long-running interest has been the spatial ecology of freshwater turtles. Following a couple of decades of research on the reproductive biology of painted turtles, I have recently directed my research efforts toward the thermal ecology of turtles and even more recently on water snakes. In addition, I have had the opportunity to study the spatial and social ecology of Microlophus lizards on the west coast of Ecuador and on Galapagos. Another avenue of research that has been the focus of my lab in recent years is the phenomenon of substrate color-induced melanization in freshwater turtles.
