I am a broadly trained Physical Geographer with interests in fluvial and coastal geomorphology, and field applications of geospatial technologies. My research focuses broadly on the interactions between water, sediments, and large wood, and the impacts of extreme events and human activities on these processes. More specifically I’ve looked at 1) the storage, transport, and geomorphic effects of wood in river channels; 2) the impacts of extreme floods on fluvial processes, 3) the impacts of extreme hurricanes on beach sand redistribution, and 4) the impact of dam removals on geomorphic processes. Methodologically I blend traditional geomorphic field techniques with contemporary survey technologies such as Field-Based GIS, RTK GPS, LiDAR, SONAR, and UAV applications for which I hold a current FAA Part 107 certification. My research has occurred across a wide range of physical geographies including the Ozarks, the Southern Appalachian Blue Ridge and Piedmont, the Atlantic and Gulf Coastal Plain, the Ecuadorian and Peruvian Andes, and coastal Jamaica.
