Nitrogen Cycling in Coastal Ecosystems:
How does climate change alter benthic-pelagic coupling? What are the rates and controls of nitrogen fixation in estuaries? What's the role of hypoxia and pH in shifting benthic metabolism? Are sediment sources or sinks of nitric oxide? What's the role of permeable sediments in removing nitrogen?

Oysters as Biogeochemical Engineers:
How do oyster habitats (e.g., reefs, aquaculture) alter benthic metabolism? Do oysters increase nitrogen removal via denitrification? What's the greenhouse gas footprint of oysters? Can we use oysters to mitigate excess nitrogen?

New Lab Directions:
Disease ecology: Is macroalgae a refuge for pathogenic Vibrio? Heterosigma: do sediments supply nitric oxides to toxic phytoplankton? Coastal Carbon: a new share model and a novel suite of sensors.
