  Dr. Xiaoyuan Yan was trained as a soil scientist with an emphasis on carbon and nitrogen cycling. He is currently working on carbon and nutrient dynamics at watershed scale, aiming at mitigating greenhouse gas emission and non-point source pollution simultaneously. He is particularly interested in quantifying denitrification rates across landscape and determining their controlling factors.

  Research Areas

  Greenhouse gas emission from cropland and wetland

  Denitrification and anammox

  Soil carbon and nitrogen interaction

  Agricultural non-point source pollution
