My primary research focus is climatic variability over the last 2,000 years and its impact on human systems and forest ecosystems. Amongst a range of related topics, my research team uses tree rings to reconstruct 1) atmospheric circulation patterns(link is external) 2) extreme climate events(link is external) including wildfire(link is external) and 3) the terrestrial carbon cycle.link is external) Innovative aspects of my research include multi-proxy approaches i.e. combining tree-ring data with other high-resolution proxies(link is external) and documentary data(link is external) and synchronization with the approaches used by climate process and modeling experts e.g. reconstruction of the North Atlantic(link is external) and North Pacific Jet link is external)stream) I cover all of these topics in a broad audience book about tree rings, climate history, and human history. Tree Story: The History of the World Written in Rings link is external)will be published by Johns Hopkins University Press in April 2020.
