Henri Grissino-Mayer is a professor of geography and director of the Laboratory of Tree-Ring Science. He uses dendrochronology, the science of tree rings, to learn about the past environment. He uses tree-ring data to analyze the history of wildfires in the Southeastern US, examine how climate has changed over recent centuries, and absolutely date when historic structures and objects (such as musical instruments) were created. He and his students have appeared in television documentaries shown on the History Channel, the Discovery Channel, the Investigation Discovery Channel, the Learning Channel, the Weather Channel, the National Geographic Channel, and Court TV.
