Research Interests

My biggest research interest is in the role of soil physical characteristics (e.g., pore size distribution and moisture content) to the formation of the microbial hotspot, carbon accumulation, and trace gas emission. Influenced by my major advisor Dr. Alexandra Kravchenko, I use a combination of novel methodological approaches. I use X-ray microtomography technique to analyze soil pore/matrix structures and organic matter distribution. To examine microbial activity, I use Zymography to locate soil extracellular enzymes in 2-dimension. Also, I track the transport of plant-derived carbon and nitrogen by using Stable Isotope Labeling methods.
My current research is based on switchgrass production system. Switchgrass is a promising second-generation bioenergy crop, but its environmental performance has not been fully investigated. As a graduate student collaborator at Kellogg Biological Station, I am studying the decomposition of switchgrass residues as a potential driver of nitrous oxide hotspots.
