Membership in academic organizations: Chinese System Simulation Association member Committee on Life System Simulation, fellow Chinese Bio-mathematics Association, member Chinese Ecology Association, member Research Directions: Modeling energy dynamics in ecosystem Computer simulation on ecosystem and other ecological processes Teaching : Fundamentals of computer science Computer program architecture The application of mathematics in ecological science (a graduate course) Research: I believe energy characteristics are essential attributes of life activities, and energy dynamics is the key clue of any ecological process, where dynamic processes in ecosystems including physiological systems can be simulated by energy dynamic models. With the help of model analyses, we can predict what event will occur, and when it does occur, what root cause it could be that leads to the occurrence of this event. Also, based on model analyses, we know how to control process developments if we want to reach certain goals or see certain patterns into which the ecosystem would develop. I developed an energy dynamic model in order to simulate various dynamic processes in ecosystems and have been using it for years, while making conscious efforts in improving it so as to reach a more realistic structure in the process of building the model This model has been used to successfully explain many classical problems in ecosystem, such as predation and control. Now, using this model, I have developed a quantitative expression for ecosystem structure, its functions, and their relationships, which facilitate quantitative explanations of transitions within an ecosystem. It is hopeful that some complex processes in ecosystems can be explained, possibly including evolution phenomena. Researches in ecological processes, at present, usually require a long period of time and take on a large scale to carry out, while involving in complex problems. Without an advanced theory and analyses that are based on mathematical models, it's often difficult to make a remarkable progress with just a routine approach. I believe any breakthrough in modern ecology research depends on introductions of new ideas and methods rather than large sums of data analysis and canonical treatment. It is my sincere wish that those who are interested in my projects and agree with my ideas would join me in the exploration. Selected publications 1.
