UNIVERSITY PARK, Pa. — Katherine Freeman, Evan Pugh University Professor of Geosciences in Penn State’s College of Earth and Mineral Sciences, was honored with the Arthur L. Day Medal from the Geological Society of America on Oct. 10 at the society’s annual meeting in Portland, Oregon.
The medal, one of the GSA’s highest honors, recognizes “outstanding distinction in contributing to geologic knowledge through the application of physics and chemistry to the solution of geologic problems.”
Freeman received the medal in recognition of "her international leadership and ground-breaking work enabling carbon and hydrogen isotopic analysis of individual organic molecules extracted from geological and environmental materials.” Her studies moved these methods into the mainstream of geochemistry and fostered their use to solve important geologic problems, especially in the study of past climates.
“I am honored to receive the Arthur L. Day Medal from the Geological Society of America,” Freeman said. “I am grateful to my students, postdocs and collaborators who made the work possible — and fun!”
