I am interested in the impact of different watershed management practices on the sources, transformations, and retention of carbon, nitrogen, and phosphorus in streams and rivers. My research studies the effects of managing point sources in a large river-estuarine system, as well as the management of diffuse sources in headwater streams. I use stable isotopic (nitrogen and oxygen isotopes of nitrate) and fluorescence spectroscopy (EEMs) techniques to trace sources of carbon and nitrogen and detect biogeochemical transformations in each of my study ecosystems. Concerning urban headwaters, I am particularly interested in investigating the effectiveness of stream restoration vs. different stormwater management practices (i.e. detention ponds, constructed wetlands, and bioretention) to reduce exports of carbon and nutrients.
