Scientist & writer
I am a dendroclimatologist: I use the rings in trees to study the climate of the past and how it has influenced ecosystems and human history.
I am a professor in the Laboratory of Tree-Ring Research at the University of Arizona. You can find more information about my research and my research group here.
I wrote Tree Story, a broad audience book about tree rings, climate history, and human history. It is published by Johns Hopkins University Press and has been translated into Dutch (my mother tongue): Wat Bomen Ons Vertellen.
"Trees remember. They record history and they don't lie."
