Biography

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 Interest

Statistical modeling, population characteristics, and anything with management implications.
