Research Interests
My overall research interests are directed towards understanding the genetic and physiological responses of microorganisms that control biogeochemical cycles in various environments, ranging from lakes to soils. Specifically, my lab focuses on describing how microorganisms interact with minerals that control geochemical cycles. Minerals, such as iron (Fe) and manganese (Mn) oxides, are ubiquitous in the environment and important for controlling the fate of toxic metals (e.g. lead, chromium), carbon cycling, and soil stability.
 
As a member of the CMU Institute for Great Lakes Research, my lab is also interested in understanding how these dynamic processes function in the Great Lakes Basin. To understand these processes my lab utilizes a range of conventional and sophisticated techniques in molecular biology, biochemistry, and geochemistry.
