Professor Gehrlein has had teaching activities on campus with a focus on graduate and undergraduate courses in operations management. He also taught in the Executive MBA Program, the DuPont MBA Program and under USAID program grants in both Varna, Bulgaria and Sarajevo, Bosnia. Other international teaching took place in Geneva, Switzerland and at the University of Caen, France. He was also active for several years in consulting activities, primarily involving statistical analysis for the marketing communications department at DuPont.

Gehrlein’s research interests span topics in operations management, social choice theory, statistics and mathematics. His early research activities after completing a post-doctoral fellowship were supported for three years by National Science Foundation Grants. This research effort has resulted in 125 journal articles, fourteen book chapters, fifty proceedings papers and numerous presentations at academic conferences and workshops in twelve countries. Invited guest lectures have also been presented in France, Italy, Turkey and The Netherlands. This output has been achieved with significant support from fifty different coauthors, including two papers with Nobel laureate in economics Eric Maskin. As a result of collaboration with two coauthors, he is listed with Erdos Number 2 by the Erdos Number Project at University of Michigan. One of his journal articles was cited in the award presentation of Nobel laureate in economics Amartya Sen.

He was honored in 2021, along with his frequent coauthor Dominique Lepelley, by an international Festschrift volume entitled Evaluating Voting Systems with Probability Models that was coedited by Mostapha Diss and Vincent Merlin. Much of his work has been summarized in four books that he has either authored or coauthored with Dominique Lepelley. Three other volumes have also been either edited or coedited. He is currently active in pursuits related to the significant impact of bycatch from trawling in the commercial fishing industry.
