Kristopher Hollingsworth

Since October 2023, Kris Hollingsworth has served as site coordinator for MathHappens at the Children's Museum of Southern Minnesota. After finishing their PhD in the Summer of 2020 at the University of Delaware, Kris spent two years teaching a rigorous, proof-based Calculus sequence for advanced high-school students at the University of Minnesota's Talented Youth Mathematics Program (UMTYMP) in Minneapolis. They are now a tenure-track Assistant Professor at the University of Minnesota, Mankato in the Department of Mathematics and Statistics. Additionally, Kris has coached Math League teams, organized events for the Delaware Science Olympiad, taught at the prestigious MathPath Summer Camp, and generally tried to use his mathematical training to improve his community through mathematically themed outreach activities. Kris lives in Southwestern Minnesota with their partner and spends most of their free time being taken on long walks by Gemma (their Aussie Beagledor), shoveling excessive amounts of snow and ice in the frigid north, and hoping someday to have enough time to actually unpack all the boxes they dragged from Delaware to Minnesota and hasn't opened yet.
