As in the case of most researchers, I spent the early part of my career in learning the fundamentals—in this case, solid-state NMR as practiced in the late 1960s and early 1970s. This background eventually gave me employment at the National Research Council of Canada where my expertise was seen as a valuable asset to venture into detailed studies of dynamics in clathrate hydrates. This led to the exploration of new approaches, e.g., the exploration of 129Xe NMR spectroscopy for the characterization of pore space as well as the exploration of new materials—generally classifiable as guest–host and supramolecular solids. The research group which I led for a number of years, with expanded expertise in NMR and complementary techniques, became known for the ability to characterize complex materials where disorder and dynamics were a problem. With the recent global interest in natural gas hydrates, my interests have swung back to concentrating on understanding structures and processes in this challenging class of labile minerals.
