Research Interests:

  • Terrestrial carbon cycle
  • Soil-based greenhouse gas emissions
  • Crop phenology
  • Long-range transport of air pollution
  • Process-based land surface model

Environmental change is one of the most significant challenges we face over the coming century, especially for vulnerable ecosystems and island nations. Since 2000, I started to focus on the interrelationship between climate change and socioeconomic impact. My previous works have the influential power on establishment of real-time radioactive observation/warning system and policy towards sustainable development. These improvements and positive feedbacks were motivating my life for our beautiful planet earth and a better life.

I would like to apply process-based models and field measurements for a better understanding of interactions between the atmosphere and terrestrial ecosystems. The gaps between modeling assumption and field technique limitation require a sound coupling. In the future, I like to extend my research area from agro-ecosystems to sensitive ecosystems in East Asia. The impacts of long-range transport of air pollutants and trace gases on downwind ecosystems can be revealed by using a creative experiment design, such as the stable isotope method, transport model and multi-agent observation systems. The international corporation project in East Asia will integrate the my previous academic experiences in Canada, U.S. and Taiwan.
