Research Interests

  • Cenozoic paleoceanography and paleoclimate
  • Antarctic climate evolution
  • Micropaleontology (diatoms)
  • Geochemical proxies of paleoenvironmental change

I am a paleoceanographer with a focus on Southern Ocean response to changing climate. My research uses stable isotope geochemistry and diatom micropaleontology in marine sediments to examine the evolution of the Antarctic cryosphere through the Cenozoic. In support of these aims, I also participate in collaborative investigations into the modern controls on phytoplankton community structure. This modern-process research underscores the role of biogenic marine sedimentation as a uniquely sensitive recorder of past conditions, both geochemically and from an assemblage-based perspective.
