My primary research interest is in applying new physical process-based frameworks to geomorphic patterns, for the purpose of contributing to general explanations that can improve our predictive abilities. Topics I have studied include the process of flooding and river channel switching on river deltas and alluvial fans, the effect of vegetation on the stability and shape of sand dunes, and the controls on channel shape and migration in braided rivers. I have employed a variety of methods in my research, including planning and executing experiments, analyzing images and topography data with scripts written in Matlab and ImageJ, using field-collected repeat LiDAR surveys and grain size data, proposing new analytical treatments, and writing cellular automaton models.
My current research at Lamont-Doherty emphasizes applying these interests and approaches to problems relevant to predicting and mitigating the effects of natural hazards. One group I work with is the BanglaPIRE research group studying geohazards in Bangladesh. Within this effort, my research focuses on the interaction between tectonics and river channel movement, on both long and abrupt timescales. The second group I work with is an interdisciplinary team of computer scientists, civil engineers, and earth scientists. We are studying landslide erosion and runout through a combination of numerical models and experiments of granular flow in an enhanced-gravity centrifuge environment.
