I have broad, interdisciplinary training, including microbiology (University of Iowa, PhD, Environmental Engineering), sustainable development (MS, Purdue University, Environmental Engineering), and engineering (BS, Purdue University, Mechanical Engineering). Before I came to ISU, I did a postdoc at Michigan State University with C. Titus Brown and James Tiedje where I worked with integrating biological sequencing data to answer questions in microbial ecology. I also was a staff scientist at Argonne National Laboratory where I continued studying microbial communities in environments such as the soil and gut. I am currently a professor in Agricultural and Biosystems Engineering.
My research interests focus on understanding and managing environmental microbial communities. I am involved in projects to identify microbial drivers of biogeochemical cycling and their response to climate change, understanding contributions of microbial genes, individuals, and groups to population function and dynamics, and detection of biomarkers for environmental health. I am interested in unifying large, heterogeneous datasets investigate complex interactions within environment.
My research studying natural microbial communities impacts our global challenges of sustainably managing climate change, developing bioenergy resources, and understanding human and animal health. By leveraging sequencing technologies, my lab accesses critical microbial processes that impact our daily lives. We work in collaboration with other researchers to unify datasets that help us monitor and manage environmental health and safety.
