A senior University of Michigan medical school faculty member linked to a $276 million insider trading case has retired.
The university said last week that it was investigating the role of Dr. Sidney Gilman, and spokesman Pete Barkey tells the Detroit Free Press that the 80-year-old retired Tuesday.
Federal investigators say Gilman was involved with ex-hedge fund manager Mathew Martoma, who's accused of getting secret, advance results of tests on an experimental Alzheimer's drug.
Martoma was arrested Nov. 20 on charges filed in New York federal court.
Gilman was a neurology professor and chaired a safety committee overseeing trials of the drug.
Gilman lawyer Marc Mukasey has said his client is cooperating with investigators and has a non-prosecution agreement with prosecutors.
