Duffin studied physics and electrical engineering (bachelor's degree) at the University of Illinois at Urbana-Champaign , where he received his doctorate in physics on thermomagnetic and galvanomagnetic effects under Harold Mott-Smith and David Bourgin in 1935 . He was then a lecturer at Purdue University and the University of Illinois . During the Second World War he was at the Carnegie Institution in Washington, DC , where he did research for the US Navy, among other things, on mine clearance. From 1946 to 1988 he was Professor of Mathematics at Carnegie Mellon University in Pittsburgh. He also worked as a consultant for the electronics company Westinghouse .
Duffin dealt, among other things, with the theory of electrical networks and operations research . Raoul Bott is one of his students , with whom he worked on the analysis of electrical networks (Duffin-Bott synthesis, Duffin-Bott inverse). In 1949 he refuted Hadamard and Boggio's assumption .
