My students and I study the transport of water, energy, nutrients, and other solutes through watersheds. We work at scales ranging from a few centimeters to whole river networks. Our research is particularly focused on how physical, chemical, and biological processes interact to produce the ecosystem functions and quality that we observe in the world around us. Our research methods include field-based experiments (you in a stream!) and numerical models. We apply our findings to predict the transport and fate of water, nutrients, and pollutants in response to key drives such as land use change, resource management, and climate change.
