Geomorphology, sedimentary processes, climate change, hydrology, physical limnology, natural hazards.

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.
