Gregg Davidson
Author, BioLogos Voices
Gregg Davidson has been a professor of Geology & Geological Engineering since 1996, specializing in hydrology and geochemistry, and serving for many years as the department chair. His professional writing is divided between the purely scientific, usually tied in some way to water, and the intersection of science and Christian faith. Gregg has a passion for understanding and communicating the harmony (or at least lack of conflict) that exists between the Bible and modern science.
