Education and career

Pulleyblank obtained his Ph.D. from the University of Waterloo in 1973; his thesis, supervised by Jack Edmonds, concerned perfect matching theory from the point of view of polyhedral combinatorics.[2] He worked at IBM beginning in the late 1960s and then returned to academia in 1974,[3] as a professor at the University of Calgary, before moving back to Waterloo in 1982.[4] At Waterloo, he held the CP/NSERC Chair of Optimization and Computer Applications.[1][4] In 1990 he began a second stint at IBM, where his work included leading the Blue Gene project.[1][3] He was promoted to vice president in 2004,[4] and retired from IBM in 2010, at which time he joined the West Point faculty.[4][5]

The College of Saint Rose, in Albany, New York, and McMaster University, in Ontario, Canada, have both given Pulleyblank honorary degrees. He is also a recipient of the Alberta Centennial Medal, a fellow of INFORMS, and (since 2010) a member of the National Academy of Engineering.[1][6]
