Michael McCartney is a research assistant professor in the Minnesota AIS Research Center (MAISRC) and the Department of Fisheries, Wildlife and Conservation Biology at UMN. Dr. McCartney earned a Ph.D. at SUNY Stony Brook and did postdocs at the Smithsonian Tropical Research Institute and Florida State University. He came to MAISRC to study zebra mussels after 13 years on the faculty of the University of North Carolina, Wilmington. His research program has featured a broad range of marine and freshwater invertebrates and fishes—with a focus on mollusks—and he often uses molecular biology to study problems in ecology, evolution and conservation. By using the most modern genetic and genomic tools available, Dr. McCartney aims to describe the pathways of zebra mussel spread in Minnesota and to develop early detection methods that target zebra mussel veliger larvae. The goal of his research is to help AIS managers around the state direct their efforts towards areas of the highest risk of invasion.
