Fyfe, dean of the faculty of science at the University of Western Ontario, London and Canada, will teach and lecture on campus and interact with public school children in two separate visits in April and May 1991.An expert on geochemistry and the earth's environment, Fyfe will create a course, "Earth: Planet Under Stress." In public lectures he will address global change, waste disposal and resources for the future.

"Dr. Fyfe is an enthralling speaker who can hold an audience spellbound," said David S. Chapman, Utah professor of geology and geophysics who helped arrange the visit. "He is an outstanding and imaginative researcher, and a major figure in the international geoscience world."
