In May 1980 he was awarded an Executive Masters in Business Administration from The Carlton School of Business, University of Minnesota.

At that time fewer than one thousand persons held both a Ph.D. degree in a physical science and an M.B.A.

Dr. Corcoran began his research career at General Mills, Inc., Golden Valley, Minnesota from 1967 to 1976 where his interest was in the development of new food additives. He then studied ultraviolet curable coatings at the Adhesives, Sealants and Coating Division of 3M Company at 3M's Research Center in Maplewood, Minnesota.

He accepted an offer in 1980 from Ethyl Corporation in Baton Rouge, Louisiana to lead a Research & Commercial Development team that obtained one of the first approvals by the US Environmental Protection Agency under their newly established Toxic Substances Control Act for the successful commercialization of a new polyurethane chemical.

In 1993 he moved to Orangeburg, South Carolina and supervised the Pharmaceutical Quality Assurance Department of Ethyl's Albemarle Corporation.

Together with a specialty team he formed, they obtained approval from the US Food & Drug Administration in 1997 for Propofol, the most widely used pharmaceutical anesthetic. After retirement in 2005, he and his wife moved to Cookeville, Tennessee to be closer to his daughter and her family.

They met in June 1965 when they were both students at the University of Wisconsin-Madison. They were blessed with a son, John Michael in and a daughter, Carol Louise.

He and his wife, Mary, enjoyed travel, especially their visit to the historical and religious sites in Israel in 1993 and ten years later to find their ancestors' birthplaces in Austria, Ukraine, Poland, Ireland, and Germany.
