I am interested in processes that reshape Earth's surface. I have broad interests
in dynamic process-form linkages within the hydrologic-geomorphic system that have
implications for society, ecology, and the evolution of landscapes. This led me to
investigate the evolution of fluvial deposits influenced by changing tectonic and
climatic forcings in the Andes (Bywater-Reyes et al., 2010). In my dissertation research I quantified interactions between riparian vegetation
and fluvial processes. My research used field, remote sensing, and numerical techniques
to investigate both seedling vulnerability to floods (Bywater-Reyes et al., 2015)
and how riparian vegetation engineers channels by changing flow and sediment transport
regimes at the bar and reach scales (Bywater-Reyes et al., 2017a).
During my tenure as a postdoctoral scholar, I quantified the spatial and temporal
patterns in turbidity and suspended sediment using long-term water quality data. I
identified watershed geology as a fundamental control on both overall sediment yields
as well as vulnerability to management (Bywater-Reyes et al., 2017b).
As a new faculty member at UNC I am interested in starting local projects quantifying
how factors such as climate change and disturbance impact water resources along the
