Greg Francis is first and foremost a teacher. As an undergraduate at Brigham Young University he taught recitation sections normally reserved for graduate students. Later as a graduate student studying plasma physics at MIT he regularly found opportunities to teach classes normally reserved for research faculty. After finishing his doctorate in 1987 he served as a postdoctoral fellow at Lawrence Livermore National Laboratories. Although his day job gave him the opportunity to work with world-class scientists on exciting problems, he found that he really preferred his night job, teaching physics classes at the local community college. In 1990, Greg joined the Physics Education Research Group at the University of Washington-Seattle, learning the "science" of effective physics teaching. Since 1992 Greg has continued to experiment with active learning approaches in large introductory classes at Montana State University where he is currently an Associate Professor of Physics.Kirkpatrick, Larry is the author of 'Physics A World View', published 2006 under ISBN 9780495010883 and ISBN 049501088X.
