Our research addresses the variability of past climates and the biogeographic and ecosystem consequences of that variability, with implications for gauging threats of ongoing climate change, land use, and population growth.

  • Paleoclimatology
    • Paleoclimate model intercomparison
    • Data analysis and visualization
  • Paleoecology
    • Multi-proxy studies from lake sediments
    • Influences of natural disturbances and climate change on the composition and structure of forests, at several scales in space and time, through the use of interdisciplinary approaches
    • Fire history from lake sediments and tree rings
  • Environmental Modeling
    • Vegetation modeling responses to past climate change
  • Biogeography
    • Reconstructing regional vegetation response to climate change
    • Refugia of biodiversity during the glacial maximum and other climate events
