Stacey Stoffregen

Job Title

  • Associate Professor of Chemistry
    Chemistry, College of Arts and Sciences


Stacey's research interests are in the area of atmospheric organic chemistry, particularly the decomposition pathways of organic pollutants. Two specific categories of organic molecules currently under investigation include 1) hydroxyalkyl hydroperoxides which are formed via alkene ozonolysis reactions and subsequent reaction with water vapor in the troposphere and 2) hydrofluoroolefins which are non-chlorine containing refrigerants possessing many of the desired characteristics of chlorofluorocarbon alternatives. Stacey's group uses quantum mechanical methods to computationally model the interaction of these types of molecules with light and their possible degradation pathways. Stacey is also interested in the incorporation of Green Chemistry in the organic laboratory curriculum and has worked with students to develop more environmentally friendly organic synthesis exercises.

  • Iowa State University - Ph.D., Chemistry, 2007


Stacey grew up in Cottage Grove, Minnesota, earned a BA in Chemistry at St. Olaf College in Northfield, Minnesota and a Ph.D. in Chemistry with a Biomolecular Sciences Specialization at Iowa State University in Ames, Iowa. After graduate school Stacey served as a Visiting Assistant Professor at Macalester College for one year where she taught general chemistry, organic chemistry, and a special topics course in organic photochemistry. She then moved to the University of Wisconsin-River Falls where she served as an Assistant Professor from the Fall of 2008 until the Spring of 2014 and an Associate Professor from the Fall of 2015 until the Spring of 2017 teaching courses primarily in organic chemistry.

Stacey lives in Lake Elmo, Minnesota with her wonderful family, including her husband Bill, her daughter Heidi, her son Hans, and her two dogs Oskar and Heike. The entire family enjoys cross-country skiing, cooking, gardening, canoeing, camping, and hiking. Stacey and her family are members at Christ Lutheran Church in Lake Elmo, where she enjoys serving as a Sunday school teacher to kindergarten and first grade children.
