Welcome to the watershed biogeochemistry and ecohydrology research group, located in the Department of Hydrology and Water Resources at the University of Arizona

Research in our group is broadly focused on interactions between the biosphere and the cycling of water, energy, and biogeochemicals, primarily carbon and nutrients. Our approach is guided by first principles, yet cognizant of, and in many cases focused on identifying, the non-linearities (e.g. resilience, resistance, and assembly) and thresholds (e.g. physical, phenological, successional) that characterize biophysical systems. This work is inherently interdisciplinary requiring skills, expertise, and methods from both physical and biological sciences. Our research is not restricted to a particular environment or ecosystem, and our group has worked in arctic tundra, forested catchments, semi-arid catchments, river-, stream-, lake- and wetland-ecosystems, and urban environments. Individual projects may seek to identify new process knowledge linking physical and biological processes, develop rules for scaling point-scale processes to catchments or landscapes, or, typically in concert with colleagues, incorporate this knowledge into predictive modeling frameworks. Most of our work has both a basic science component addressing knowledge gaps in understanding ecosystem structure and function, and an applied component addressing stakeholder needs.
