Stacey Stoffregen came to the department in the Fall of 2008 and teaches courses primarily in the area of organic chemistry. Stacey grew up in Cottage Grove, Minnesota, went to St. Olaf College for her undergraduate studies, then spent five years in Ames, Iowa where she pursued her graduate studies. While at Iowa State University she also served as an instructor of general chemistry and a teaching assistant in general and organic chemistry laboratory and discussion sections. After leaving Ames, 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.

Stacey’s research background is in two areas, 1) the design of sequence specific synthetic peptidases and 2) the photochemical reactivity and computational modeling of sulfur ylides.

Stacey’s interests outside of chemistry include spending time with her wonderful family, including her husband Bill, her daughter Heidi, her son Hans, and her dogs Oskar and Heike. The entire family enjoys cross-country skiing, cooking, gardening, canoeing, camping, and hiking.
