Tian is an expert in the areas of global biogeochemical cycles, climate change, ecosystem and earth system modeling.
Tian's primary interest is in the understanding of coupled biogeochemical cycles in the Earth’s ecosystems and dynamics of coupled natural and human systems by using a systems approach and merging new technology (GIS, GPS, RS and Computer Simulation). His research fields have covered a range of topics, including studies of carbon, nitrogen and water cycles in a range of ecosystems across the globe including boreal and temperate forests in North America and East Asia, tropical forests in the Amazon Basin and Southeast Asia, savannas in Africa, grasslands in United States and Mongolia, and croplands in China and United States.
Dr. Tian’s research and teaching concentrate on the broad area of climate and sustainability sciences.
