# Fred Longstaffe

Frederick John Longstaffe CM, Ph.D., FRSC is the former Provost and vice-president (Academic) at The University of Western Ontario. He is an earth science researcher. His current focus is on applying knowledge of stable isotopes to various fields of study.

## Biography

Longstaffe earned a BSc (Hons) from the University of Windsor and a PhD in Geology from McMaster University. In 1978, he was a researcher at the University of Alberta as a Killam Post-Doctoral Scholar. After that he joined that university's Department of Geology faculty. In 1987, Longstaffe moved to the Western as a full professor in Geology and opened the Laboratory for Stable Isotope Science. The labs principal research areas are environmental geochemistry and clastic diagenesis, with special emphasis on the application of stable isotopes and other biogeochemical methods to studies of the environment and climate change. The Departments of Geology and Geophysics were merged in 1993. He became the chair of the newly formed Department of Earth Sciences. Dr. Longstaffe gave up that position in 1999 to take on the larger role of Dean of the Faculty of Science. In July 2005, Longstaffe became the university's Provost and VP Academic.
Longstaffe's research has attracted substantial funding from Natural Sciences and Engineering Research Council, Social Science and Humanities Research Council and Canada Foundation for Innovation. His current research focuses on the use of stable isotopes to study earth and environmental science, ecosystems, oil sands, and anthropology.
Longstaffe has served as president of the Geological Association of Canada. He has frequently served on Natural Sciences and Engineering Research Council and Royal Society of Canada committees.
He resides in Ilderton, Ontario.
