Breifly Personal Statement
My favorite subject in high school was the mathematics and physics. It was just amazing to me that you could explain the behavior of real things using mathematics. When I was an undergraduate student at North University of China in the 2003, I have taken part in the research seminar of the mathematical model that was hold by Prof. Zhen Jin at Department of Mathematics. He challenged and interested me in a deep way, are responsible for me being a researcher in science. After graduating with a BS in Applied Chemistry, I stay at Department of Mathematics to study the mathematical models related the ecology and epidemic spreading.
Since April 2009, I started a PhD project at the NIOO-KNAW (Department of Spatial Ecology) in cooperation of the University of Groningen–Centre for Ecological and Evolutionary Studies group. At NIOO, I work on a project on ecosytem functioning of spatial patterning in mussel beds. My works include the theoretical model and experimental works for intertidal ecosystems.

Projects
Currently I am interested in underdtanding aggegation mechanisms and behaviors of bivalves communities from the spatial multi-scale perspective. My PhD work involves a combination of mathematical modeling, computer simulation, laboratory and field work. Why we study the bivalve species? Bivalves form reefs that maintain aquatic ecosystems in a clear water regime because their filter water sediments. In addition, they maintain biodiversity by providing habitat to aquatic species. Low abundance regime can be induced by harvesting and enviromental changing. Once bivalves are depleted, their filtering function is lost and the over enrichment of nutrients make the system vulnerable to eutrophication or even hypoxia.
- Aggregation and control of carrying capacity of bivalves in intertidal communities
- Spatial patterns formation and their ecosystem functioning
