In addition to my administrative duties as Director of the museum, I remain interested in the broad fields of molluscan ecology and paleoecology. My research focuses primarily on the use of growth increments and stable isotopes in the shells of marine molluscs to interpret life history information as well as to reconstruct paleoenvironments and paleoclimates. Many of the research questions that I have addressed used material from the Cenozoic and modern environments of Florida, although certainly not exclusively. A growing research emphasis involves shells from archaeological deposits and examines questions of site seasonality and paleoclimate variability.
