Summary
Dr. Csank is a paleoclimatologist & paleoecologist with expertise in stable isotope geochemistry and dendrochronology. His primary research involves the use of stable isotope dendrochronology to reconstruct past climates and the impacts of climate change on trees over time periods ranging from the Pliocene to the present. Csank also works at the intersection of human and physical geography in the growing area of critical physical geography using historic timbers to study legacies of exploitation related to the timber trade. Csank also works to understand historic land use patterns and to find novel ways to use paleodata to inform climate adaptation by understanding risk, vulnerability and resiliency. Past projects include studies ranging from climate reconstructions to land use change to studies of drought and tree mortality. Ongoing projects include reconstructions of climate and ecosystems in the Arctic, the response of trees to climatic change, reconstructions of large-scale atmospheric patterns, streamflow and lake levels and reconstructing historic atmospheric pollution. In his research Dr. Csank has worked in diverse settings both locally and internationally including the Canadian Arctic, Greenland, throughout the western US, eastern Canada, Bermuda, Jamaica and Italy.
