Upson Chair of Public Discourse, Professor of Geosciences

Taylor Science Center 1013

Barbara Tewksbury is a structural geologist and lead PI of the Desert Eyes Project, which combines analysis of high resolution satellite imagery with field work and geophysics to study bedrock structures in the Western Desert of Egypt. The Desert Eyes Project discovered the first extensive on-land exposure of polygonal faults, a style of faults that had been previously studied almost exclusively in the subsurface using marine seismic data. For the past decade, Tewksbury and her Egyptian colleagues, along with more than 20 Hamilton geo students, have mapped an extensive and previously unrecognized network of synclines in the Western Desert of Egypt and interpreted them as sag structures indicating deep (hypogene) dissolution in the host limestones.

Tewksbury has been a leader in the national geoscience education community for more than 25 years. She has led over 150 workshops for faculty across the country and abroad, and she was co-PI of the 15-year-long NSF-funded project On the Cutting Edge. She currently has the honor of being one of a small group of instructors who design and teach the classroom and field geology training for newly selected NASA astronauts (Hamilton magazine Through the Eyes of a Geologist: Training Astronauts to Think Like Geologists).
