Current Visiting Scholars


Dr. Yun Zhang visiting Purdue University, September 2014 -September 2015

Yun Zhang is a lecturer from the College of Land and Environment at Shenyang Agricultural University and will stay at Purdue to work with Professor Timothy Filley in the Department of Earth, Atmospheric, and Planetary Sciences from September 2014-September 2015. Her research is focused on characterizing the individual components of soil organic matter (SOM) such as polysaccharides, amino sugars, amino acids, lignin, and lipids) using physical (e.g. size and density) and chemical separation (e.g. thermochemolysis, pyrolysis) methods. She will also work on using stable carbon isotope to estimate the abundance and nature of stabilized SOM components in the residue and soil fractions. 


Ms. Chang Liu visiting Purdue University, September 2014 – September 2016

Chang Liu will be a visiting graduate student scholar working on soil pollution control and water-saving irrigation of crop production. She is a Ph. D student in soil science, supervised by Professor Yulong Zhang, Shenyang Agricultural University. Her current research includes: soil phosphorus forms under different irrigation practices in greenhouse production; effect of irrigation methods on the leaching potential of soil phosphorus under greenhouse conditions.


Ms. Tingyu Hou is a visiting scholar starting her research work in Sept. 2014

Ms. Tingyu Hou is currently a PhD candidate at Northwest A&F University in the major of Environmental Science. For the next two years, Tingyu has the opportunity to work with Prof. Timothy Filley on the Critical Zone Observatory for Intensively Managed Landscapes (IML-CZO) project. She would be to work on how land management and erosion influence soil organic matter – particle associations. To control the vulnerability of SOM, She will use a combination of soil organic chemistry, stable isotope analysis, and particle separations to track fast transformations of plant and microbial organic matter in soil aggregates and on mineral surfaces. She will works with a team of other graduates students and visiting scholars at Purdue and other participating US universities. Her data, related to the physical and chemicalstructure of SOM will provide the needed information critical to improving both short-term and long-term carbon budget predictions in the critical zone.
