Research Interests

I have diverse research interests. By using stable isotope labelling and natural abundance approaches, I devote to 1) explore effects of N deposition on forest ecosystems; 2) reveal tree growth and N cycling in the past 150 years; 3) quantify nitrogenous gas losses from terrestrial ecosystems soils; 4) examine if plants have N uptake preference or plasticity and link them to plant biodiversity; and 5) quantify atmospheric inorganic N and partition their N sources in the present time and in the past.

So far I have published more than 100 peer-viewed papers, of which 60 were SCI papers. As leading and/or correspondence author, I have published 27 papers in international journals, including PNAS, Global Change Biology, Atmospheric chemistry and Physics, Analytical Chemistry, Environmental Science and Technology, Ecosystems, Biogeosciences, Oecologia, Journal of Geophysical Research, Tellus B, Plant and Soil, Forest Ecology and Management. My total SCI citation is1800 times, and my H-index is 16 based on web of science. My research ID is G-4456-2012.
