Educational Background

  • Ph.D., 2005, Marine and Atmospheric Sciences
    Stony Brook UniversityState University of New York
  • M.A., 2000, Ecology

Research Interests

  • I am interested in the natural, climatic, and anthropogenic processes that govern coastal systems.
  • Paleochannels as pathways for submarine groundwater discharge in the Mississippi River Delta (Funded By NSF, with Tulane and U.N.C. Chapel Hill).
  • Sediment dynamics and biogeochemical cycling in the Wax Lake Delta (Funded by LA Sea Grant, with Brian Roberts- LUMCON; Student: Ciara Chambers -Tulane University)
  • Morphodynamics and Ecological Functioning in the West Bay Diversion (Funded by National Wildlife Federation student; Student: Alex Ameen - Tulane University)
  • Submarine groundwater discharge in deltaic settings (with Tulane University and the University of North Carolina, Chapel Hill)

Current Projects

  • How Atmospheric Centers of Influence Short-Term Sea Level Change (with Stony Brook University)
  • Metagenomics Dynmamics in Oil Impacted and Non-Impacted Marshes in Barataria Bay (with Tulane and Los Alamos National Laboratory).
  • Impacts of Deepwater Horizon spill on the chemistry of coastal wetlands (with Texas A&M; LSU and Georgia Tech)
  • Hurricane impacts on Louisiana's Coast (CREST)
  • The Development of a River Dominated Coastal Wetlands Observatory (Funded by LEAG, with Collaborators at UNO and Texas A&M)
  • Dynamics of the 2011 flood on the Atchafalaya River Shelf (with Louisiana State University).
  • Determination of subsidence rates in the northern Gulf of Mexico (with Stony Brook University and The University of Texas, Austin)
  • Examination of biomarkers in coastal sediments (with Texas A+M University).
