My research interests focus on the morphodynamics of rivers at all scales from steepland streams to large rivers. I am engaged in long-term studies of sediment transport and stability in Fraser River. Sediment transport is also studied in an experimental program conducted in the stream dynamics laboratory at Simon Fraser University in association with Professor Jeremy Vendittti. In addition, I am interested in world fluvial sediment yield, fluvial landscape evolution over intermediate time scales (order 10,000 years), and in the history and methodology of geomorphology. I am a registered Professional Geoscientist in the Province of British Columbia.
