Paleoclimate and Environmental Change

Establishing a baseline of natural climate variability over the past 2,000 years is essential to accurately predicting regional responses to anthropogenic climate change.  My research focus is reconstructing temperature and hydroclimatic variability in the Gulf of Mexico/Subtropical Atlantic Ocean using a broad range of different paleoclimate archives.  In addition to generating proxy-based paleoclimate records, I am working on proxy development and calibration studies to improve our ability to quantify past changes in temperature, salinity and precipitation in both terrestrial and marine environments.
