Eve Emshwillers research interests center on the ethnobotany, evolution, and conservation of crop plants and their wild relatives. Her research has focused principally on the origin of polyploidy, domestication, and ongoing evolution of the Andean tuber crop oca, Oxalis tuberosa, and its wild allies. Her current research includes an international collaborative project on phylogeny of the genus Oxalis and a study of the distribution of clonal genotypes of cultivated oca as an example of the evolution of clonally-propagated crops under human influence. She has been a member of the faculty of the Department of Botany at University of Wisconsin - Madison since August 2006.
