George E. McGill,
B.A., Carleton College, 1953; M.S., Minnesota, 1955; Ph.D., Princeton, 1958.
Emeritus Professor for Mars and Venus studies.
Structural and Planetary Geology

George McGill received his B.A. degree from Carleton College in 1953 with a major in geology and a minor in biology. M.S. and Ph.D. degrees in geology were completed at the University of Minnesota in 1955 and Princeton University in 1958. Although he remained a generalist throughout, he acquired a special interest in structural geology while in residence at Princeton. McGill joined the faculty of the University of Massachusetts in 1958 and served as Department Head from 1977 to 1984 and 1988 to 1993.

Until 1970, McGill conducted field research on the structural geology and stratigraphy of the Montana Rockies, and laboratory research involving high-pressure rock deformation. Since 1970, most of his research has been in planetary geology, with emphasis on structural geology and crustal evolution of terrestrial planets, including relevant earth-analogue field studies in the Colorado Plateau area. Professor McGill was a member of the Science Steering Group and on the Radar Mapper Team for the Pioneer Venus Project of NASA, and compiled major global summaries of the geology and tectonics of Venus as a result of this activity. He also was a Guest Investigator for the Magellan radar mapping mission to Venus from 1990 to 1993.
