Recent and current projects include: bed material transport in gravel rivers and mechanics of braided rivers (field site in Canadian Rockies plus small-scale model studies); stream morphology, land-use impacts on river systems, stream habitat and stream channel design (southern Ontario); regional denudation and sediment sources in glaciated landscapes; climate change impacts on fluvial processes in Canada.
