I think it’s fair to say that my upbringing on a nearly treeless expanse of Canadian prairie gave rise to my interests in forests and forestry. These interests took me to the University of British Columbia where I first studied forest science, specializing in forest soils, and then went on to obtain a master’s degree in forest biometrics. Following this, I worked for several years as a biometrician with a forestry consulting firm in B.C., which gave me the opportunity to work in resource inventory design and analysis, on forest growth modeling, and on diverse quantitative and statistical modeling projects. But eventually I was drawn back to academics and moved to the east coast to earn a Ph.D. in biometrics from Yale University.
My research is focused on the development of probability sampling methods and statistical modeling techniques for natural resource assessment and monitoring. Recently my work has been directed to the design of sampling strategies for forest inventory and the survey of downed woody materials, and to the application of nonlinear mixture models for characterizing forest growth and mortality. Results of this research have been published in the forestry, ecological, and statistical literature.
