Presently, I am a postdoctoral associate at Texas A&M University – Corpus Christi. I was born and grew up on Zhoushan archipelago in the East China Sea. I completed my doctoral degree in the Ecology Program (Conservation Biology Area of Emphasis) at the University of California, Davis in 2006. Following my Ph.D., I conducted postdoctoral research at the Dexter National Fish Hatchery and Technology Center (The U. S. Fish and Wildlife Service) and at North Dakota State University.

Research & Teaching Interests
I am interested in a diverse spectrum of conservation and population genetics questions. My research considers organisms that sustain the biological diversity and systems that promote the evolutionary potential. Currently, I am working with colleagues on the species of (1) cyprinids (Cyprinidae), suckers (Catostomidae) and cyprinodonts (Cyprinodontidae) in North America; (2) riffle gobies (Sicydiinae) in the Pacific Ocean; and (3) pygmy sleepers (Butinae) in coastal West Africa.

I am interested in teaching in a variety of biological subjects. Most recently, I instructed two upper-division undergraduate / graduate-level courses at North Dakota State University, (1) Conservation Biology and (2) Evolution. I enjoy engaging with students in both the class room and the laboratory settings.
