Research Interests

My primary research interest is paleoceanography of the Cretaceous and Cenozoic, using the deep-sea sedimentary record to investigate the role of the deep oceans in global heat transport during different overall climate states. In particular, I use radiogenic isotopes, stable isotopes, and trace element geochemistry to reconstruct the patterns of deep-water formation and circulation that operated under different boundary conditions.

Please note that Dr. Thomas does not have any positions available for graduate students or post-doctoral scholars.
