My research interests are in past and contemporary landscape processes and specifically how environmental variability has modified or changed these process dynamics. As well, I am interested in how our knowledge of past processes is informed through the use of paleoenvironmental proxies and rely on sedimentary records (e.g., clastic varve or annually laminated sedimentary units) and tree ring growth records (e.g., eccentric growth and reaction wood) to help reconstruct past landscape processes. In the context of future global change or landuse management changes, high-resolution records will help us understand how surface processes in the past have responded to variability and how they might change in the future.

In addition, I am actively evaluating instrument records (temperature, precipitation, discharge, water quality) as a way of establishing baseline conditions to which future scenarios are compared. I am also developing and/or improving field instruments used in monitoring and measuring sedimentary processes in lakes and streams.

I am always excited to speak with enthusiastic scholars looking to pursue potential graduate (MSc) or senior undergraduate research opportunities. In particular, individuals driven by curiosity and a keen sense for understanding the processes that shape the world around us through a geoscience lens. Our work looks at how fluvial geomorphology and ecohydrology intersect within the context of disturbed systems (e.g., land use land change, climate variability, pre & post disasters or extreme events). Opportunities for Fall 2024 include sediment budget based on sediment cores, ice and winter conditions and their impact on channel morphodynamics, and tool development to track fluvial geomorphic changes in restored channels. Successful applicants will receive funding following our department’s graduate financial support policy. Funds for fieldwork, conference attendance and other opportunities for professional development are also available and will be allocated based on the research projects. Students with strong backgrounds & interest in Physical Geography, Physical and Environmental Sciences are encouraged to contact me to discuss available projects and funding.
