Distinguished Researchers - 1996

 
John A. Weil
   Spring, 1996
John A. Weil
Department of Chemistry
College of Arts and Science

Dr. Weil holds a M.Sc. (1950) and Ph.D. (1955) from the University of Chicago. Professor Weil joined the Department of Chemistry and Chemical Engineering, University of Saskatchewan in 1971.

Dr. Weil had research appointments at the Fermi Institute of Nuclear Studies and the Institute for the Study of Metals, and there contributed to pioneering studies of the effect of high pressure on atomic self-diffusion in alkali metals.

Upon his graduation from Chicago, he was Corning Glass Postdoctoral Fellow and served on the Princeton University faculty. In 1959, he joined the research staff of the Argonne National Laboratory (USA). He was a Fulbright Visiting Lecturer in New Zealand during 1967-68. At these centres he developed ongoing research interests in dioxygen carriers and a variety of free-radical systems, and initiated long-term studies of magnetic species in silicates.

Since coming to the University of Saskatchewan, Dr. Weil's research efforts have centered on the defect structure of crystalline quartz, and also featured various organic free-radical systems and sophisticated theoretical studies. One publication was chosen by the American Physical Society to be included in the list of Most Memorable Papers (1934-1990) in the American Journal of Physics.

Known for his work on Electron Paramagnetic Resonance (EPR) spectroscopy, Dr. Weil has pioneered the understanding of the structures of paramagnetic defects in crystalline quartz. Quartz is a key material in the electronic, optics and glass industries. He has contributed extensively to the understanding of the chemistry of organic free-radical systems; his research group’s continuing studies of chemical reactions and crystal structures of the nitroaromatic hydrazyl/hydrazine system may have environmental uses.

Dr. Weil’s experimental thoroughness and comprehensive treatment of data are well-known and he is sought as a collaborative by colleagues in England, France, Germany, Japan, South Korea, New Zealand and the USA.

Dr. Weil has developed an EPR centre at the University of Saskatchewan, and has supervised 20 Ph.D. and M.Sc. students. His research contributions include nearly 150 refereed papers published in leading scientific journals, and he co-authored two books, including a major introductory text in the field of EPR.

In recognition of his creative and pioneering work in the field of electron paramagnetic resonance, Dr. Weil has been honored as the Erkine Lecturer at the University of Canterbury, New Zealand (1987). He was elected Fellow of the Canadian Institute of Chemistry (1980). In 1994, he held a Royal Society Visiting Fellowship at Oxford University. He was appointed Thorvaldson Professor for 1983-1988 at our University. His earned D.Sc. (1985) from the University demonstrates the breadth of his achievement as an experimental and theoretical chemical physicist.

Delwyn G. Fredlund
Professor of Civil Engineering
College of Engineering

Professor Fredlund, a native of Norquay, Saskatchewan, joined the University of Saskatchewan as an Assistant Professor in 1966, moving through the ranks to a Full Professor in 1976. Dr. Fredlund was awarded his Bachelor of Engineering, University of Saskatchewan (1962) and his M.Sc. and Ph.D. in Geotechnical Engineering, University of Alberta (1964,1973).

Having become interested in the problems of unsaturated soils in the prairie region, his doctoral dissertation marked one of the first fundamental treatments of unsaturated soils by introducing the concept of stress state variables. This concept has become the cornerstone treatment of unsaturated soils mechanics in geotechnical engineering.

He is the author or co-author of over 160 refereed journal articles, conference proceedings, technical papers, and chapters in edited collections. In 1993 he co-authored Soil Mechanics for Unsaturated Soils, the first major text on unsaturated soil mechanics published.

His expertise is recognized internationally and, through the International Development Research Centre, he has developed three exchange programs and, through the Canadian International Development Agency, project links with Vietnam. He has served as a research consultant to the Government of Hong Kong, the U.S. Army Corps of Engineers, and to Saskatchewan Highways among others.

Dr. Fredlund’s scholarly work has been recognized in many ways. He has held or holds positions as Associate Editor of the Canadian Geotechnical Journal and Chair of the Expansive Soils Committee for both the Canadian Geotechnical Society and the International Society for Soil Mechanics and Foundation Engineering. He received the Distinguished Service Award of the Association of Professional Engineers of Saskatchewan (1994); and was elected Fellow of the Engineering Institute of Canada (1993). He is a member of the NSERC Civil Engineering Grant Selection Committee.

Dr. Fredlund has supervised over 50 M.Sc. and Ph.D. students, including four who have become colleagues at the University of Saskatchewan, and many who came from Hong Kong, China, South East Asia and South America. Professor Fredlund believes that international outreach through the training of qualified personnel is one of the best forms of aid.
