Welcome to the Royer Laboratory website.

TEST 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 emerging wastewater contaminants, such as pharmaceutical compounds. 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 School of Public & Environmental Affairs at Indiana University.

I am also an adjunct professor in the Department of Biology at IU and can serve as the major advisor for students enrolled in the doctoral program in Biology.
