The search for a new University of Iowa president has been narrowed down to four candidates, the fourth of whom was announced Monday morning.

The candidates are in the running to replace former UI President Sally Mason, who retired in July. Jean Robillard, vice president for medical affairs, is currently serving as interim president.

Each candidate has visited the campus in Iowa City while the search continues. Following the visits, the state Board of Regents will meet Thursday to interview each candidate and select a new president of the university.

The first candidate is Marvin Krislov, the president of Oberlin College, a private liberal college in Ohio with a student population of 3,000. He has occupied the position since 2007 and also teaches political science.

The second candidate is Michael Bernstein, provost and senior vice president for academic affairs at Tulane University in New Orleans, La. Bernstein previously served as a professor at Princeton University and the University of California-San Diego.

The third candidate is Joseph Steinmetz, executive vice president and provost at Ohio State University. Throughout his career, including his time with Ohio State, Steinmetz has been a professor of psychology and neuroscience.

The fourth and final candidate, named Monday morning, is Bruce Harreld. He currently serves as the managing principal at Executing Strategy, located in Avon, Colo. He has also held positions with IBM and the Boston Market Company, as well as teaching positions with Northwestern University and Harvard University.
