PhD, McMaster University, 1984
Physical geography, fluvial processes.
Research Interests and Areas of Expertise
My research interests are in fluvial geomorphology and hydrology. This research is conducted at several national and international locations and includes applications of acoustic technology, floods and their effect on rivers, the impact of global change, dune morphology and processes, fluvial turbidity currents, river confluences and the impact of urbanization on stream channel erosion.
I am a practicing member of the Association of Professional Geoscientists of Ontario. Recent activities include advising the Canadian International Development Agency on the use of hydrologic modelling as a basis for planning in drainage basins in southern Africa, and studying the impact of placer mining on sensitive fish habitat in the Yukon for Indian and Northern Affairs Canada.
