Eve Emshwiller is researching the systematics and ethnobotany of the Andean tuber crop oca (Oxalis tuberosa) and its wild relatives. Her ethnobotanical work in Peru focuses on traditional management of cultivated oca and how agricultural practices may be affecting the genetic diversity of the crop. Her systematic research has studied the origins of domestication and polyploidy of the cultigen through a study of oca's relationships with wild Oxalis species.
