Professor, Department of Ecology and Evolutionary Biology
Williams College, 1996, BA, Biology; University of California at Davis, 2003, PhD, Population Biology
Evolutionary ecologist whose work elucidates the fundamental principles governing adaptive evolution. He addresses such questions through a combination of theory, observational natural history, and field and laboratory experiments, combining disparate biological disciplines (ecology, evolution, behavior, genetics, and immunology).
For seminal insights into the ecological and selective forces maintaining trait variation within populations, ecological consequences of trait variation within populations, adaptive divergence between populations, and speciation.
