I obtained my PhD in 1988 from Shandong University (China). I joined UNE in 1991, firstly as a postdoctoral research fellow working with Prof. E.N. Dancer on an ARC supported project. While at UNE, I visited Heriot-Watt University (UK) under an Australian Academy of Science and the Royal Society exchange fellowship (1996), visited the Chinese Academy of Science under two Australian Academy of Science exchange fellowships (1999, 2001), visited the University of Tokyo and Waseda University under an Australian Academy of Science and JSPS fellowship (2006), and visited the Institute of Mathematics and Applications at the University of Minnesota as a long term visitor (2012). I also visited the National Center of Theoretical Sciences of Taiwan as a visiting professor (2002, 2007). I was an Adjunct Professor of Qufu Normal University (China) during 2004-2010.

Primary Research Area/sNonlinear elliptic and parabolic differential equations; Nonlinear functional analysis; Mathematical models in biology and spatial ecology
My research concerns mainly with nonlinear elliptic and parabolic equations and nonlinear functional analysis. My current research interest focuses on the existence, uniqueness and qualitative properties of solutions of various nonlinear partial differential equations, mostly arising from applied sciences, such as mathematical biology, invasion ecology and chemical reaction theory.
I've been the principal supervisor of several PhD and Master's degree students. For scholarship opportunities, see Postgraduate Scholarships.
