Tracy Gregg, associate professor of geology, has been elected as a Fellow of the Geology Society of America (GSA), an honor recognized at the society’s annual fall meeting last week in Charlotte.

GSA Fellows are selected in recognition of distinguished contributions to the geosciences. Gregg, a volcanologist, studies volcanoes and lava flows on Earth, Mars, Venus and Io, one of Jupiter’s moons. She has expertise in interpreting geologic formations throughout the solar system for clues about how landscapes are formed.

At the GSA meeting, Gregg presented the results of research into lunar sinuous rilles. She also viewed a preprint of her new book, “Modeling Volcanic Processes: The Physics and Mathematics of Volcanism,” which she edited with Sarah Fagents of the University of Hawaii and Rosaly Lopes of NASA’s Jet Propulsion Laboratory.

The book is an advanced-level text that targets graduate students, providing an analysis of the physics of volcanic behavior and examining models used to explain volcanic processes. Research in these areas is critical to assessing and mitigating the danger that eruptions pose to people who live near volcanoes.

“Modeling Volcanic Processes,” published by Cambridge University Press, will be available in February.
