Current Visiting Professors

TiDa GeProfessor TiDa Ge, Professor, Institute of Subtropical Agriculture, Chinese Academy of Sciences, Changsha, China. March 2014- March 2015.

Research Interests: Prof. Tida Ge’s main area of research has focused on understanding below-ground processes with specific focus on C and N behavior in soil-plant-microbial systems. His current work include C flow in paddy agricultural systems, the mechanistic understanding of carbon fluxes and pools in plant-soil systems by isotopic tracing and microbial molecular techniques. His research philosophy involves maximum collaboration with colleagues at both a national and international level.


Jufeng ZhengProfessor Jufeng Zheng, Associate Professor, Nanjing Agriculture University, Nanjing, China. October 2015- October 2016.

Research Interests: Prof. Jufeng Zheng’s main area of research has focused on understanding how intensive cultivation and litter (plant, biochar) influence below-ground soil processes related to C cycling. While a visiting scholar at Purdue he will be working with Filley in a comparison of metal-associated organic matter among sites with a variety of hill slopes the Intensively Managed Landscapes (IML) – Critical Zone Observatory (CZO) and the Northeast of China.
