Professional title

Senior Research Scientist


Josh works on fisheries and aquatic ecology research within lakes and streams all around the Great Lakes basin, and inland Minnesota. Josh’s recent interests include learning how native species interact with invasive species, and identifying mechanisms of over-land transport supporting the spread of aquatic invasive species into new waterbodies. Collectively, this work will help researchers, anglers, and recreational boaters limit their risk of transporting invasive species as undetected “hitchhikers.”
