My research is centered on modern carbonate sediments and climate change (sea level). In particular, I ask questions about the response of coastal depositional climates to changes in sea level, energy and climate. In way ways does the density of seagrass control the accumulation of lime mud, control the species composition of mollusks, and control sand movement into and out of seagrass meadows? What controls the migration behavior of tidal channels in sand shoals? How quickly do tidal channels fill with sediment? What diagenetic effects occur on the sea floor? Which occur immediately after subaerial exposure? Answers to directed questions such as these provide insights into the processes which shape our world today and which likely shape our world in the past.

Possible thesis/dissertation topics:

  • Climate indicators in coral skeletons.
  • Paleostorm evidence in Pleistocene Coral Reef lithologies.
  • Lagoon depositional processes and seagrass density.

Current/recent graduate student research:

  • Carbon budget of a Pleistocene aquifer.
  • Bacterial communities in Andros Island aquifer.
  • Pleistocene sea-level fluctuations revealed in coastal rock cores.
  • Influence of seagrass communities on mollusc communities.
  • Death assemblage of seagrass mollusc communities.
