About me

I work with Tamlin Pavelsky in the Global Hydrology Lab. I study physical, ecological, and built aspects of rivers from headwater streams to coasts. I use satellite remote sensing, field campaigns using in-situ sensors, and simple models to ask theoretical and applied research questions within three major themes: connectivity and networks, environmental heterogeneity and change, and environmental sensing. My current work focuses on how river-lake network structure affects spatial and temporal patterns in suspended sediment using satellite remote sensing of rivers and lakes across the US.
