Taxa Studied: Invertebrate Animals, Vertebrate Animals
Techniques Employed: QTL Mapping, SNP Mapping, Sectioning for Histology
Research Description: My research interests involve the study of ecology and evolution, including mechanistic work at the molecular and organismal levels, field studies that document the importance of phenotypic variation, and a comparative view of the long-term consequences of this variation. To do so, my lab often integrates molecular and quantitative genetic techniques with experimental laboratory and field studies, largely focusing on the impact of environmental and genetic factors during development in mediating the expression of physiological, behavioral, and life-history traits. Using these conceptual approaches in concert with comparative techniques enables us to assess important biological issues, including (1) the biological significance of diverse sex-determining mechanisms and (2) the impacts of environmental and genetic factors on variation in early life-history traits. Our focal study organisms are usually reptiles, especially turtles, but we also work extensively with lizards and with the nematode C. elegans.
