Yunkai Li (Google Scholar)

I am a professor at the Center for International Marine studies and the College of Marine Sciences at Shanghai Ocean University. My research interests include the biology and ecology of shark and squid species, stable isotope ecology and conservation biology of endangered species.
I received my Ph.D. in Aquatic Biology (2009) at East China Normal University, Shanghai, China. I was also a visiting Ph.D candidate to Yong Chen's Lab (supported by China Scholarship Council) at the University of Maine, Orono ME 04469, USA (2007-2008) and a visiting scholar of Dr. Yuying Zhang and Dr. Michael R.Heithaus (supported by China Scholarship Council) at Florida International University, North Miami FL 33181, USA (2015-2016).
