Drew T Downs, Ph.D.


I am a geologist at the U.S. Geological Survey California Volcano Observatory. My work focuses on physical volcanology, geochronology, geochemistry, and petrography, and their applications for understanding eruptions from basaltic to rhyolitic volcanoes. Much of my expertise with the California Volcano Observatory has been to use various geologic datasets to map volcanoes and volcanic fields, and then work with collaborators to understand the volcanic hazards of a region. I am currently working on projects in California, Saudi Arabia, and New Zealand.
