Education

  1. 2013 Ph.D. in Soil Science, Swedish University of Agricultural Sciences, Department of Soil and Environment, Uppsala, Sweden
  2. 2010 M.Sc. in Soil Science, Swedish University of Agricultural Sciences, Department of Soil and Environment, Uppsala, Sweden
  3. 2007 B.Sc. in Environmental Sciences, Northwest Agricultural & Forestry University, College of Natural Resources and Environment, Yangling, China

I am currently a post-doc working on SWAT modeling, phosphorus indices and compiling experimental data, with the aim of appropriate management of animal manure (especially over winter) to reduce nutrient losses to water. I have a research background of soil science, specialized in water quality management. During PhD, I investigated phosphorus leaching as influenced by animal manure and catch crops, by carrying out laboratory and field experiments and model simulations.
