Research interests:
Broadly, I am interested in natural and human-mediated regional and global biogeochemical change. Within this field, I am particularly interested in the biogeochemistry of river nutrient transport, and in understanding how humans have changed, are changing, and will continue to change fluxes of nutrients from land to sea on local, regional, and global scales. I am also interested in the ecosystem impacts of human-driven nutrient mobilization and in improving our understanding of the role that aquatic systems play in the modulation of Earth’s climate through the production and consumption of greenhouse gases. I use experimental, remote sensing, and modeling approaches to elucidate transport, transformation and impacts of bio-active elements such as carbon, nitrogen and phosphorus. Current and past projects focus on regional nutrient and greenhouse gas dynamics in the Mexico's Yaqui Valley and in California's Central Valley. I also work at the global scale, and have developed spatially explicit, global models of nutrient and organic matter export by rivers as part of a UNESCO-IOC-funded research project called Global Nutrient Export from Watersheds (Global NEWS). In addition to these projects, I am currently working to develop a research focus on the biogeochemistry of Pacific Northwest watersheds.
