My research is at the interface of environmental biogeochemistry, near-surface hydrology, and sustainability science. I seek to understand how people change the ways that elements (such as carbon, nitrogen, and sulfur) transform within and transport through terrestrial and aquatic ecosystems, and how those changes feed back to affect our wellbeing. My past and current projects have included understanding the interactions of biogeochemical and hydrologic processes in human-dominated systems, such as agricultural systems in California, and in more remote areas, such as relatively undisturbed, high elevation locations along the American Cordillera. I am interested not only in conducting research, but also in working toward sustainable solutions related to water, nutrient, and pesticide management. In addition, I am involved in designing large-scale observatory networks, and exploring compatibility of networks within the United States and internationally.
