This page is a work in progress.....stay tuned!

Terrestrial Silica Cycling:
​What role does "terrestrial" biology play in regulating silica availability in downstream receiving waters? How do vegetated coastal systems impact the marine silica cycle?

---

Coastal Greenhouse Gas Fluxes:
​What's the magnitude of nitrous oxide and methane fluxes in coastal systems? What environmental parameters control these fluxes? How do nitrous oxide fluxes change under low pH and low oxygen conditions? 

---

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?

Watershed Nutrient Export:
​How does climate change alter nutrient export from forested watersheds? How do urban landscapes alter nutrient export and water quality? 

---

Nitrogen Cycling in Coastal Ecosystems:
How does climate change alter benthic-pelagic coupling? What are the rates & controls of N fixation in estuaries? in aquatic systems? What's the role of hypoxia and pH in shifting benthic metabolism? What's the role of permeable sediments in removing nitrogen?

New Lab Directions:
Aquaculture and Vibrio: Is macroalgae a refuge for pathogenic Vibrio species?  Heterosigma: do sediments  supply nitric oxide to toxic phytoplankton?  ​Coastal Carbon: developing a new share model and a novel suite of sensors.
