Professional career

He is a Professor of Mathematics at Northeastern University. He did his undergraduate studies at Boston College. He received his Ph.D. from Brandeis University in 1975 under the direction of Edgar Henry Brown Jr. and Harold Levine. In 1975 he became an AMS Centennial Fellow at MIT and a year later he joined the Brown University faculty as Tamarkind instructor. In 1979 Gaffney became professor at Northeastern University where he has remained ever since. He has served as department chair, graduate director, chair of the undergraduate curriculum committee, and faculty senator.[2]
