I am primarily interested in systematics and evolutionary biology of plants. In particular, I am interested in the origin and evolution of plant endemics on oceanic islands, including the Macaronesian Islands in the Atlantic Ocean and Jeju and Ulleung Island in Korea. I am also interested in revealing complex evolutionary history of polyploidy and homoploidy lineages of flowering plants. Additional research interests include conservation genetics of rare and endangered species, population genetics of invasive weedy species, ethnobotany, plant domestication, and phylogeography of east Asian plants. A variety of techniques and molecular markers are utilized to unravel the phylogenetic patterns and underlying processes generating plant diversity.
