Research Areas

Our research interests include three areas, evolutionary genomics, evolution of self-incompatibility systems and speciation, and natural variation and adaptation. The plant species we study include but not limited to the dicot model species, Arabidopsis thaliana, and related species in the Brassicaceae and the monocot model species, rice (Oryza sativa), and its relatives.
