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. 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

Ezra Moses Lead ecologist and data scientist
My work is motivated by the stories we can uncover from agricultural soil data to help build a more sustainable and equitable food system. I am interested in using statistical and visual techniques to facilitate understanding of soil processes by researchers and farmers alike, with main topics of interest including soil nutrient management and cover crops.

Eric Potash Post-doc
A mathematician by training, Dr. Potash is supporting the re-sampling of the >400 pedons originally sampled in the Illinois soil survey initiated in 1899, and leads an evaluation of increasing sensitivity of soil organic and inorganic carbon measurements.

Michael Douglass Head field technician
I thoroughly enjoy working as a research tech in the field environment and trying to tame down the variables which accompany it. I’ve been fortunate to work with exceptional people along the way and gain experience in a range of settings: from agroforestry, fruit & vegetable production, cover crops, corn/soy farming, and weed management.

Taylor Berkshire-Akers Lab manager & Head lab technician
As part of my duties as lab manager and head lab technician, I oversee the operations of the wet labs and coordinate multiple research projects with field and lab components. I focus on cover crops (seeding rates, different ways of seeding, and grazing) and their role in nutrient cycling, specifically nitrogen. Research aside, I enjoy spending time with my family, listening to podcasts, renovating my house, and spending time outside (when it’s warm).
