About Barbara

Barbara A. Schaal is the Mary-Dell Chilton Distinguished Professor of Biology and Professor of Environmental Studies by courtesy appointment in the Department of Biology at Washington University in St. Louis. She received her BS degree with honors in Biology from the University of Illinois at Chicago and her MS and PhD in population biology from Yale University in 1974. A pioneering figure in plant evolutionary biology, Schaal was among the first plant scientists to employ molecular biology-based approaches to investigate evolutionary processes. Her research specializes in the evolutionary genetics of plants, molecular evolution of genes, systematics, and quantitative genetics. She has examined genetic structure, population differentiation, gene flow, and domestication in crop species including rice, cassava, wild bananas, Solanum pimpinellifolium, Spondias purpurea, and Oryza rufipogon.
