He began his biological career at the age of fourteen when he and his sister studied the growth and movements of a population of eastern painted turtles in Rhode Island. His research now focuses on organismal biology, blending physiology, morphology, behavior, and ecology in an evolutionary perspective. Undergraduate students regularly participate in his research and are coauthors of many of his pub- lications. He especially enjoys teaching undergraduates and has taught introductory biology and courses in vertebrate zoology, functional ecology, herpetology, environ- mental physiology, and animal behavior.
