Research Interests

Understanding ecosystem functions that affect water quality, climate regulation, and carbon sequestration in natural and human-modified ecosystems.

Research Description

We study the retention and processing of nutrients (nitrogen, carbon, and phosphorus) and the flux of greenhouse gases in wetlands, streams, forests, and urban ecosystems. We use approaches from ecosystem ecology and biogeochemistry in our work and collaborate across social and biophysical sciences. We are also interested in understanding the biogeochemical functions of restored, engineered, and degraded ecosystems
