My research seeks to understand the mechanistic processes and hydrologic conditions required to create surface features like river channels, alluvial fans, and deltas, and understand how these landscapes and the processes that build them evolve under changing climates. This has implications for hazard prediction and mitigation during extreme events and constraining the rates and histories of aqueous processes on paleo-landscapes and other planetary surfaces (like Mars). The latter is a prerequisite for understanding where and when life could have evolved within our solar system. I approach this work from the perspective of a geoscientist, integrating topographic, sedimentologic and hydrologic datasets from the field with physical experiments (as geologically significant flow events are often difficult and/or impossible to observe). The unifying theme of my work is to combine geomorphic/geologic processes and hydrologic/climatic science: this combination is specifically necessary to understand past climates (on Earth or other planets) because the data is recorded in the geologic record and its surface expression, and the physical processes of interest are climatic in nature.
