Christopher S. Reigstad, Ph.D.

Associate Professor of Biology

College of Arts and Sciences

Dr. Reigstad teaches a variety of science courses at Concordia-Chicago, including Anatomy & Physiology, Microbiology, and Concepts in Chemistry & Biology. His areas of research and expertise include microbiology, mammalian physiology and STEM education.

Prior to joining the faculty at CUC, he completed a postdoctoral fellowship at the University of Gothenburg (Sweden), worked as a Senior Research Fellow at the Mayo Clinic, and served as Community Faculty at Metropolitan State University in St. Paul, MN.
