Josh Dumke

Senior Research Scientist


Josh works on fisheries and aquatic ecology research within lakes and streams all around the Great Lakes basin, and inland Minnesota. Research interests include learning how native species interact with invasive species, identifying mechanisms of over-land transport supporting the spread of aquatic invasive species into new waterbodies, and ways to improve detection of invasive species. Josh spends all possible time hunting, fishing, trapping, milling lumber, and teaching his two boys about the outdoors and stewardship of natural resources.
