Jeffrey Ross-Ibarra is a professor in the Dept. of Evolution and Ecology at the University of California, Davis. His group works on the evolutionary genetics of maize and its wild relatives the teosintes. Research in his group uses population genetic approaches to address questions ranging from transposable element evolution to the genetics of quantitative traits, maize and human coevolution, domestication, and local adaptation. Work from his group has helped elucidate the genetics mechanisms underlying hybrid vigor in maize, and the role of demography, selection, and introgression in shaping maize evolution.
