Research Interests

As a paleoclimatologist and paleoecologist, Dr. Cohen has worked on the Holocene and Anthropocene history of mangrove dynamics on the Brazilian coast and in the Gulf of Mexico and Caribbean regions. His research interests include the use of remote sensing, fossil pollen, stable isotopes and sedimentary features to reconstruct environments impacted by sea-level fluctuations, climate changes, and hurricanes on decadal to millennial time scales.
