Research Interests

I am interested in the natural, climatic, and anthropogenic processes that govern coastal systems during times of stasis and change. Specific interests include:

• Determining the balance between subsidence and sedimentation in Barataria Bay.
• Understanding how sedimentary and biogeochemical processes govern patterns of marsh development and loss.
• The role of atmospheric variability in short-term sea level dynamics.
• Radioisotope geochemistry.
• Coastal biogeochemistry.
