Water resources, nutrient and carbon cycling, water quality, and nutrient standards

My students and I study biogeochemistry and water quality in streams and rivers. We are particularly interested in nutrients (nitrogen and phosphorus), organic carbon, and pollutants such as chloride from road salt runoff. We investigate both patterns and processes, using a combination of field studies and laboratory experiments. Most of our projects are interdisciplinary and we often collaborate with researchers in other fields of study, such as hydrology, microbiology, and aquatic entomology.

My graduate students are enrolled in the Environmental Science program in the O'Neill School of Public & Environmental Affairs at Indiana University.

I am also an adjunct professor in the Department of Biology at IU Bloomington.
