Brief Curriculum Vitae B. Sc., Toronto (1965); A.M., Harvard (1966); Ph.D. Harvard, 1970. NRC Postdoctoral Fellow Univ. of British Columbia, (1970-71). NSERC Senior Industrial Fellow, Xerox Research Centre of Canada (1980-81). Research Interests In-vivo NMR of Bone Fluorides Fluorine is an important trace nutrient whose ions accumulate in the body as substitutional impurities replacing hydroxyl groups in bone mineral. On the Erindale Campus of the University of Toronto, we have developed a non-invasive NMR method for determining the bone fluoride content of index fingers. In-vivo NMR bone fluoride and bone phosphorus measurements have potential medical applications with regard to the diagnosis and treatment of various metabolic bone diseases. Medical Physics My current
activities in medical physics include serving as a Community Member on the Research
Ethics Review Board of a teaching Hospital affiliated with the University of Toronto.
