Research Interests

High-resolution reconstructions of past climate variability using geochemical proxies (d18O, d13C, Sr/Ca, Mg/Ca, Ba/Ca) in biogenic archives (corals, sclerosponges):

  • Sea surface temperature and salinity reconstructions from paired d18O and Sr/Ca measurements (with S. Y. Cahyarini, Ph.D. 2006).
  • Tropical Atlantic variability and hurricane intensity (with S. Hetzinger, Ph.D. 2007).
  • Seasonal changes in Holocene and Last Interglacial Monsoon climate (with J. Zinke, Vrije Universiteit Amsterdam).
  • Ultra-high resolution analysis of corals and sclerosponges (SIMS, NanoSIMS) - ‘vital effects' and geochemical proxies (with T. Watanabe, Hokkaido University and K. Shirai, University of Tokyo)
  • Coral proxy records and tropical trees in the Indian Ocean - rising sea surface temperatures and rainfall variability over land (with G. Helle, FZ Jülich).


Current Research Project

Principal Investigator, ‘Assessing the role of the INDian Ocean in global climate change: a PALeo-perspective (INDOPAL)' The project forms the basis for an innovative and multi-disciplinary approach aimed at a better understanding of the role of the Indian Ocean/Monsoon system in global climate change. The project will bring together paleoclimatologists from a range of disciplines (coral paleoclimatology, dendrochronology, meteorology) and will undertake novel research in East Africa and Indonesia. The project is supported by the DFG (10/2007-09/2009), 161.000 €.
