Thomas A. (Tad) Dillhoff – Executive Director

I have had a lifelong interest in the natural world, and in the 1980s began the study of paleobotany. Since then I have focused on the Tertiary paleobotany of western North America. My research interests include paleoecology, paleoclimatology and biogeography with a special interest in the floras of the Middle Miocene Columbia River Basalts. I have a Bachelor of Science degree in biology from the University of Washington with a minor in botany. Besides my duties at the Evolving Earth Foundation, I am a Curatorial Associate with the Burke Museum at the University of Washington, and a member of the Botanical Society of America, the Geological Society of America, and the International Association of Wood Anatomists.
