PRINCETON, NJ--Princeton University received a $20 million gift with which it will establish a laboratory for the campus's new interdisciplinary Institute for Integrative Genomics, which was funded with $35 million earlier this year. The latest gift was given by the Icahn Family Foundation, whose president, Carl Icahn, graduated from Princeton in 1957 with a philosophy degree. Shirley Tilghman, who was appointed to direct the institute, said the new lab will house 12 faculty and more than 100 associated staff.
