Research Interests

• My research interests focus on determining the environmental stress on plant growth, minimizing environmental impact and optimizing production eciency for food supply system on Earth. I have worked on terrestrial carbon/greenhouse gas accounting system, agricultural process-based model, dynamic vegetation model, long-range air pollution transport model, and weather risk assessment. My research goal is to develop a hi-tech integrated farming system and monitoring/modeling tools for sustainable ecosystem.
