Steven Wilhelm is the Kenneth & Blaire Mossman Professor in the Department of Microbiology at the University of Tennessee. His research group studies the synergies between microbial communities and biogeochemical cycles in large lakes and marine systems. Lab members employ biomolecular tools - DNA and RNA sequencing, metabolomics, proteomics and PCR-based quantitative analyses - to study viruses, bacteria, cyanobacteria and algae. Their interests revolve around how microbes shape the environment, and in turn how environmental conditions shape microbial form and function. Recent studies have focused on the development of tools to study how viruses shape biogeochemical function in marine systems (the “viral shunt” hypotheses), examinations on the role of organics in trace metal scavenging in pelagic marine systems, and the development of state-of-the-art molecular tools to trace the drivers of cyanobacterial bloom formations in large lakes around the globe.
