Duffey joined the faculty of GWU in 1992 and he was granted tenure as
an Associate Professor in 1998. He holds a doctorate in
Mechanical Engineering from the University of Massachusetts at Amherst
(1992). His research and teaching interests include engineering
economics, systems design, and related methodologies and computer
tools. His research projects have been sponsored by the National
Institute of Standards and Technology (NIST), the U.S. Navy, the
National Aeronautics and Space Administration (NASA), the National
Science Foundation (NSF), the Society of Manufacturing Engineers (SME),
and other government agencies and private companies. He received
a M.S. in Manufacturing (1987) and B.S. in Physics (1985, cum laude)
from the University of Massachusetts, and a B.A. in History (1982) from
Trinity College in Hartford, CT.
Classes taught include: EMSE 260 and EMSE 160 (Engineering
Economics); EMSE 261 (Economic Analysis in Engineering Planning); EMSE
283 (Systems Engineering); EMSE 257 (Production Design); and EMSE 297
(Problems in Engineering Management)
In addition to his academic career, he has worked professionally
as an engineering consultant, journalist, and as a merchant
seaman. His hobbies include music (from traditional Irish to
experimental musical instruments), hiking, and the ancient game of go.
