Areas of Interest:
My main interest is in the areas of paleoceanography and paleoclimatology. I use a variety of approaches and geologic archives to reconstruct past climate and environmental changes. Examples include oxygen and carbon isotopic variations in marine foraminifera, ocean paleothermometry based on Mg/Ca and alkenones, geochemistry of speleothem deposits, and dendrochronology. I am particularly interested in global climate variability during the Pleistocene and Holocene, and a central focus of my research is on the evolution of the El Niño-Southern Oscillation in the equatorial Pacific Ocean and its impacts around the world.

Project Themes :

  • Reconstruction of the El Niño/Southern Oscillation history during the Holocene using planktonic foraminifera
  • Dynamics of the cold tongue-intertropical convergence zone in the eastern tropical Pacific on glacial-interglacial and millennial time scales
  • Alkenones in marine sediments as paleotemperature and paleoproductivity indicators
  • Dendroclimatologic assessment of drought frequency and intensity in the New York City environs.
  • Dendrochronologic detection of the CO2 fertilization effect in natural vegetation from the Mediterranean Sea
