Ray Wells
Ray Wells is a research geologist in the Geology, Minerals, Energy, and Geophysics Science Center. He is a structural geologist investigating the tectonic and volcanic evolution of the Pacific Northwest.
Ray Wells received his B.S. in Geological Science from Penn State, his M.S. from University of Oregon, and his Ph.D. from the University of California, Santa Cruz. He has 45 years of field experience documenting the geologic structure and earthquake hazards of the Cascadia convergent margin in Oregon and Washington, focusing primarily on the Coast Range, Seattle - Portland urban corridor, and the Columbia River Gorge.
