Chris Guiterman
My research investigates the interactions among fire, climate, vegetation, and people. My specialty is in dendrochronology, the science of using tree rings to reconstruct past environmental processes. As a dendroecologist, I tend to focus on the drivers of changing forest dynamics, including climate change, human land-use, and altered disturbance processes.
