“I grew up loving nature,” Greg Wray recalls, “and it’s still what gets me up in the morning.” Once up, Wray spends his days immersed in large-scale data analysis, studying biological diversity 21st century-style. He has focused on the evolution of gene regulation partly by studying sea urchins, an organism whose gene regulatory networks are well understood, providing an intuitive understanding of how regulation works. But the major focus of the Wray Lab is the primates: understanding how changes in gene expression might have driven many of the phenotypic traits that make us human.
