Nathaniel Marshall is a postdoctoral research fellow for the Cooperative Institute for Great Lakes Research (CIGLR) at the University of Michigan, working with Dr. Hank Vanderploeg of NOAA GLERL. Dr. Marshall’s research involves the use of environmental DNA, or eDNA, to assess aquatic diversity in the Great Lakes, and incorporating this technique into biomonitoring and bioassessment management plans. Prior to working with CIGLR and NOAA GLERL, Dr. Marshall has applied eDNA and DNA barcoding, among other genetic tools, to understand the spread of invasive species, such as the Eurasian ruffe and Dreissenid Mussels, and for establishing management efforts for threatened and endangered species, such as Unionid Mussels.
