Research Interests

1) Flows of nitrogen and phosphorus through watersheds, wetlands, and estuaries.

2) Denitrification.

3) Exchanges of nitrogen and phosphorus between sediments and overlying water.

Current Research Projects

Factors controlling discharges of nutrients from watersheds throughout the Chesapeake Bay drainage basin.

Potential of wetlands to trap nitrogen and phosphorus.

Changes in the biogeochemistry of phosphorus in sediments along an estuarine salinity gradient.
