Associate professor, PhD Guelph
Professor Walker is a geomorphologist with expertise in beach-dune geomorphology, sedimentary processes, coastal erosion, and wind (aeolian) processes. Dr. Walker's research takes place on beaches and dunes across north America in Prince Edward Island National Park (Greenwich Dunes), Haida Gwaii (Queen Charlotte Islands), Pacific Rim National Park (Tofino-Ucluelet), and Cape Cod National Seashore (Massachusetts, USA). This work involves close collaboration with Parks Canada, BC Parks, US National Park Service, the Geological Survey of Canada, and many international colleagues. Dr. Walker directs the Coastal Erosion & Dune Dynamics (CEDD) Laboratory, which studies the erosion, morphodynamics and restoration of sandy beach-dune systems and explores linkages to land use changes and climatic change impacts. CEDD Lab also studies recent geological (late Quaternary) changes in coastal landscapes using LiDAR and various dating techniques. His research is funded by NSERC, the National Science Foundation (NSF), the Canada Foundation for Innovation, Natural Resources Canada, Geological Survey of Canada, Parks Canada, and MITACS.
Professor Walker teaches Introduction to Physical Geography (GEOG103), Process Geomorphology (GEOG376), Coastal Geomorphology (GEOG476), and the Graduate Seminar in Physical Geography (GEOG537).
