Dan DavisDan Davis is a professor of geophysics at Stony Brook University. His primary area of research specialization is the tectonics of regions where plates converge, causing great earthquakes and the construction of mountain belts. Other areas of research include the application of geophysics to nuclear arms control and to the study of glacial and post-glacial geology.

Dan is a lifelong stargazer, and although during the daytime his attention is focused downward towards the Earth, that changes after dark.
