Research Areas

Our research interests include three areas, evolutionary genomics, speciation, 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.


2001 - 2005 Ph.D. in plant systematics and evolution - Molecular systematics of the tribe Oryzeae (Poaceae), Institute of Botany, Chinese Academy of Sciences, China.

1998 - 2001 M.S. in plant physiology - Metabolism of reactive oxygen species under natural drought stress in wheat strains;, Lanzhou University, China.

1994 - 1998 B.A., Undergraduate studies in biology, Northwest Normal University, China.
