Professional Experience

Professor, Department of Oceanography & Coastal Sciences, Louisiana State University, Baton Rouge, 1989- present.
Associate Professor, same as above, 1983-1989
Assistant Professor, same as above, 1979-1983
Post-Doctoral Research Associate, Laboratory for Wetland Soils and Sediments, Center for Wetland Resources, Louisiana State University, 1977-1979.


The focus of my research is applied and basic coastal plant ecology.   My primary research interests are 1) wetland and barrier island ecology and restoration and 2) environmental constraints on vegetation distribution and productivity.   More specifically, my research emphasizes the restoration and sustainability of coastal wetlands, the analysis of the causes of vegetation dieback in coastal marshes, the effects of disturbance, natural and man-induced, on the ecology and restoration of coastal vegetation and the effects of multiple stressors, including nutrient enrichment, on wetland structure and function. I have also investigated impacts and remediation of oil spills in wetland environments. I am presently assessing the use of hydraulically dredged sediment-slurries to restore degraded coastal marshes as part of the CWPPRA’s Barataria Land Bridge Restoration Project, as well as investigations of the impact of t
he Deepwater Horizon Oil Spill on coastal wetlands. My consulting activities have primarily emphasized analyses of cause of wetland land loss and impacts and remediation of oil spills.


I have taught three primary courses at LSU: Plants in Coastal Environments, Applied Coastal Plant Ecology and Human Impacts on Coastal Plant Ecosystems.
