Current Academic Service:
Editorial Board, Copeia; Editorial Board, Cuadernos de Herpetologia; Conservation Committee, Society for the Study of Amphibians and Reptiles; Adjunct Assistant Professor, Biology Department, University of New Mexico; Research Associate, Museum of Southwestern Biology, University of New Mexico; Research Affiliate, University of Alaska Museum, Fairbanks, Alaska
Research Directions:
Evolutionary ecology, population biology, and conservation biology of amphibians and reptiles. Specific research areas include: causes and consequences of shifts in the ecological niches of reptiles as they grow from small hatchlings to large adults; modeling the demographic consequences of interactions between life history and environmental stochasticity; conservation biology, especially sustainable use approaches to conserving biological diversity in developing countries. Research is carried out in Latin America and southwestern USA. I rely on field work for data collection and draw from the fields of ecological morphology, foraging theory, and physiological ecology.
