Marshall Thomsen received his undergraduate degree in 1980 from Harvard University with a concentration in physics. He received a Ph.D. in physics from Michigan State University in 1984, where his research focused on theoretical models of magnetic materials. Dr. Thomsen spent two and a half years at the University of Southern California as a post-doctoral research associate, jointly with the Department of Physics and the Department of Materials Science. His research there focused on modeling semiconductor growth. Since 1987, he has been a member of the Department of Physics and Astronomy at Eastern Michigan University. In 1988, he started teaching a one credit hour course, Ethical issues in Physics. Over the years he has continued to develop resources for the course, with the help of two National Science Foundation grants and one sabbatical. He helped facilitate the development of similar courses (with a broader focus on the Nature of Science) in the other science departments at EMU. Dr. Thomsen is currently chair of EMU’s Academic Integrity Committee. He served on the American Physical Society’s Task Force on Ethics Education 2005-6 and has since chaired an ad hoc committee to oversee the APS ethics case studies web site. His research interests in theoretical modeling have expanded to include studies of practical problems in thermodynamics.
