At a time when volcanoes, landslides, and earthquakes show us the hazards for humans on Earth, Charles G. "Chip" Groat, director of the U.S. Geological Survey, will speak about his agency's contributions to understanding the natural sciences at 5 p.m. Thursday, April 21, at the University of Rochester. His talk, part of the annual Neilly Series, will be held in the Welles-Brown Room of Rush Rhees Library on the University's River Campus. The event is free and open to the public.

For 125 years, the USGS has been the nation's primary source of information on geologic hazards, water, energy, mineral resources, and coastal and marine processes. Groat became its 13th director in 1998. He is a distinguished professional in the earth science community with more than 25 years of involvement in geological and coastal studies and resource assessments as well as directing environmental research and managing government and academic programs related to the environment.

Groat received a bachelor's degree in geology from the University of Rochester, a master of science degree in geology from the University of Massachusetts, and a doctoral degree in geology from the University of Texas at Austin. He will be introduced by John A. Tarduno, professor of geophysics and chair of the Department of Earth and Environmental Sciences at Rochester.

The Neilly Series is supported by the Andrew H. Neilly and Janet Dayton Neilly Endowment, and the River Campus Libraries. For more information, contact the library at (585) 275-4461.
