Research Interests
In general, my research focus is on process geomorphology, i.e. the scientific study of landforms and their formative processes (morphological and sedimentological responses), and the broader contemporary environmental context. My main research interests are in the study of physical processes associated with river flow (e.g. flow turbulence), sediment transport, and river channel morphology. A significant component of my experimental work has also been conducted in the Flow and Sediment Transport Research Laboratory at York University. I also most interested in exploring longer-term landscape responses to climate variability events (e.g. at the interface of rivers and coastlines). Among recent and current research projects are the following:
. Ice jams and flow characteristics in ice-covered channels.
. Modeling of riffle-pool morphology in mixed-bed channels
. The effects of land use changes on stream morphology, processes, and evolution
. Alluvial sand bedform dynamics (e.g. ripple-dune transition)
. River meandering patterns and post-glacial valley evolution
