A primary focus of my research is to evaluate evolutionary processes in the paleotropics. My research initiatives address:
- biotic replacement of one group by another in tropical ecosystems
- rates, magnitudes and timing of the replacements
- tropical environmental processes
My research area is focused in the Caribbean region, and my students and I pursue field investigations in Texas, Florida, Puerto Rico, the Dominican Republic and Barbados.
Skills and Expertise:
- Rudist bivalves
- Caribbean reefs
- Caribbean archaeology
- Olduvai Gorge
The ultimate focus of my work is to evaluate the complexity of paleobiologic and ecologic factors that combined to allow the reef ecosystem to persist over 600 million years of Earths history.
Her research examines ancient greenhouse world reefs to evaluate what was, explores today’s reefs to monitor their health, and connects the two to provide a perspective of the future health of the reef ecosystem from records of deep geological time.
An extension of my research to the Olduvai Gorge basin focuses on evaluation of the finer points of paleotropical environmental reconstructions at the time of evolving lineages of hominids.
My research explores the evolutionary history of ecosystems to evaluate biodiversity fluctuations under Earth’s changing climate regimes.
My research examines ancient ecosystems and compares them to the modern to provide a temporal perspective on future ecosystem health.
