Jeff is a Postdoctoral Research Associate in the Friesen Lab working on the oxygen-tolerant nitrogenase project and a Co-PI on the EAGER grant on recalcitrant N acquisition by free-living diazotrophs. Jeff is an ecologist working at the intersection of microbiology and biogeochemistry to understand the ecosystem-level consequences of microbial metabolism in natural systems. He graduated from Virginia Tech with a BS in Biology in 2005, then worked as a lab technician in the Pilot Plant at Novozymes Biologicals until returning to Virginia Tech for graduate school in 2008.
Jeff pursued his doctorate in the Barrett biogeochemistry lab, a part of Virginia Tech’s Stream Team/Ecosystem Research Group. There he used techniques from molecular biology, such as quantitative PCR and amplicon-based pyrosequencing, alongside field-based incubations to measure the diversity, abundance, and function, of ammonia-oxidizing microbes in temperate forest soils. At Michigan State, Jeff is using a combination of molecular techniques, stable-isotope analyses, and culture-based screens, to study free-living nitrogen fixing microbes in both standard and exotic soil environments (including coal seam fires and volcanoes…).
When he’s not thinking about soil nitrogen cycling, Jeff is more-than-likely playing the banjo.
