2007.06-now: Working at Centre for Agricultural Resources Research, Institute of Genetics and Developmental Biology, CAS. Mainly engaged in examining the effects of elevated CO₂ on crop plants, especially carbon and water processes under drought and nutrient stress. In 2007, I set up six open top chambers at Luancheng Agricultural and Ecosystem Experimental Station. Crops, including winter wheat, summer maize and tomato are exposed to elevated CO₂. Here, my knowledge of global change ecology and agronomy are smoothly combined together.

2003.09-2007.06: Ecological Centre, Chengdu Institute of Biology, CAS: mainly investigate the response of temperate forest plants (individual and ecosystem level) to elevated CO₂ and Temperature, to elevated UV-B radiation, also the nutrient cycle in natural communities and ecosystems. Our experimental sites distributed from 1 800m to 4 200m a. s .l. on Qinghai-Tibetan Plateau, in western China. We constructed enclosed-top chambers and open-top chambers (temperature are naturally increased by sunlight) to test the response of the above plants and ecosystems to elevated CO₂ and temperature.

2000.09-2003.06: investigate the effects of water deficit, nutrient stress on winter wheat production and quality. Two winter wheat varieties were exposed to 5 soil water levels and 4 nutrition levels.
