Gregory A. Wray, PhD

Professor, Department of Biology

I am an evolutionary biologist with a background in molecular and developmental biology. I'm broadly interested in the evolution of gene regulation, at the scales of single genes, networks, and genomes. A long-term project in my lab is aimed at identifying regulatory changes that contributed to the evolution of uniquely human traits, particularly with regard to diet and physiology as well as cognition and brain anatomy. Another major project is investigating the population genetics of a developmental gene regulatory network in sea urchins.
