I am an associate professor in the department of Earth and Environmental Sciences at Tulane University. I am interested in how landscapes got to where they are and where they are going. In other words, why is the surface of the earth shaped as it is, and how is it changing? Different processes control how a landscape changes through time. If we can express these processes as equations and quantify how outside forces, like rainfall or humans, drive these processes, we can start to understand why a landscape looks the way it does and how it might be changing. I am a co-developer of CHILD and Landlab, two widely used numerical tools for modeling surface processes. We use field observation, numerical landscape simulation, remotely sensed data, and other data collected by collaborators and government agencies, to explore questions that intersect hydrology, tectonics, and sedimentology, with geomorphology at the core.
