Biography

I'm currently Lead Scientist of the Pliocene Research, Interpretation & Synoptic Mapping group (PRISM) at the U.S. Geological Survey in Reston, Virginia. My primary research focus includes all aspects of Pliocene paleoclimate, but I specialize in the application of planktic foraminifera to climate change research. PRISM’s research is a vital part of the international Pliocene Model Intercomparison Project (PlioMIP).
