Professor Duffy received a B.E.E. degree from Santa Clara University in 1953. He subsequently received an M.S. in electrical engineering in 1954 and a Ph.D. in physics in 1959, both from Stanford University. After graduate school, he spent a year as a post-doctoral fellow at the Kamerlingh Onnes Laboratory of the University of Leiden in the Netherlands. Since coming to Santa Clara in 1959, he has developed and continually updated the Electronics for Scientists courses and served as department chair for sixteen years. His recent research efforts have been directed toward studying acoustic lossed in metallic elements and alloys at ultralow temperatures. Professor Duffy's pioneering research efforts at Santa Clara were recognized with his being awarded the University's Excellence in Scholarship Award.
