Dr. Shengnan Zhou Research scientist
My research interests include soil erosion and degradation in intensively managed landscapes, particularly focusing on C and P dynamics. I am currently working to determine Illinois soil legacy P using archived historical soil samples to evaluate agricultural management effects on P losses and investments in P loss reduction strategies.

Dr. Chongyang (Oliver) Li Research scientist
I have been trained as an environmental chemist and had experience with multiple elements/substances in soils regarding their application, function, and/or remediation, including biochar, heavy metals (As and Cd), radioisotopic P (32P and 33P) and enzymes. At UIUC, I mainly focus on using isotopes to trace the uptake of N, P and S from soils/fertilizers by plants, and linking them with corresponding soil enzyme assays to better understand nutrient cycling processes in soils.

Dr. Chammi Attanayake Research scientist
I study biogeochemical transformations of contaminants and nutrients in soils. Most of my research is related to studying speciation and bioavailability of trace elements in urban soils and transformations of phosphorus in submerged soils. At UIUC, I have the opportunity to extend my research to study soil enzyme activity for soil health assessments, which would make the path for me to understand transformations in soils more comprehensively. In my leisure time, I watch movies and read books. I love to travel with my family and try different food.

Dr. Suwei Xu Post-doc
My current research focuses on the phosphorus biogeochemical cycle in the environment, especially on the distribution and speciation of P in the soil environment with different agricultural management or land use. My major interest is in how different soil forming factors (i.e., climate, parent material, vegetation, etc.) or activities (i.e., deforestation, invasive species) affect the Pi and Po speciation and movement and what are the possible environment responses.

Dr. Annie Irshad Post-doc
My research interests are physiological and molecular responses of plant-microbe interaction against abiotic stresses. I have also worked on transformation and overexpression of genes against abiotic stress. I am currently working on quantifying soil N-P stocks and their contribution to crop uptake through on-farm experiments across Illinois.

Dr. Chase Kasmerchak Post-doc
My formal training is in soil science and ecosystem ecology and my research interests broadly include how land management and disturbance affect biogeochemical cycling and ecosystem function. I have worked on a wide variety of research projects in the past, including how soil morphology and carbon dynamics respond to millennial-scale vegetation change, how future changes to lake-effect snow and forest composition may affect soil methane uptake, and how the genetic diversity of trembling aspen and disturbance history influence biogeochemical cycling. At UIUC, I will be working on a variety of projects using stable and radioactive carbon isotope data to understand how vegetation and land management history affect soil carbon cycling. Outside of research, you can find me on the dance floor supporting local Chicago house music
