Joseph Mrnak

Joseph Mrnak - M.S. of Dr. Steven Chipps


I spent my childhood in the outdoors chasing waterfowl, musky, catfish, and turtles. I began working at a local marina at the age of 12, which further fostered my love for all things water. I received my B.S. degree in Fisheries and Wildlife Ecology along with a minor in GIS from Northland College in 2016. While in school I was able to work for the USFWS in Alaska, Whittlesey Creek National Wildlife Refuge in Wisconsin, as well as the USGS on the beautiful Lake Superior. After graduating, I worked for the WIDNR at the Escanaba Lake Research Station where I was able to research the mixed walleye fishery as well as develop and implement a large river IBI function (R Studio) for the state. I am now working on my master's degree studying the effect of water velocity and temperature on energy reserves, growth, survival, and dispersal distance of larval pallid sturgeon.

Research Interests
