معرفی
David L. Goldsby is a Professor and Department Chair in the Department of Earth and Environmental Science at the University of Pennsylvania. His research focuses on mineral and rock physics, particularly the rheological behavior of Earth and planetary materials. He employs experimental geophysics and materials science techniques to study deformation processes at high pressures and temperatures, with an emphasis on grain size-sensitive flow mechanisms in ice and mantle materials.
Education: Ph.D. (1997) Geophysics, University of Minnesota; M.S. (1990) Geophysics, Indiana University; B.S. (1987) Geology, Eastern Illinois University.
Research Interests: Goldsby investigates grain boundary sliding, cryomaterials (ice and icy satellites), olivine deformation, and phase transformations. His work bridges microscale mechanics (e.g., nanoindentation) and large-scale geophysical phenomena like glacial flow and mantle dynamics. Recent studies explore the role of water, temperature, and grain size on material strength and viscoelasticity, with applications to planetary science and seismic processes.
His research trends emphasize interdisciplinary methods, including synchrotron imaging, MCMC modeling, and advanced deformation experiments. Collaborations focus on planetary ice rheology, fault mechanics, and lithospheric strength. He teaches courses in structural geology, glaciology, and geophysics.
Labs/Teams: Goldsby Lab at Penn, focused on experimental mineral physics and planetary materials. Affiliations: American Geophysical Union.
Grants/Advising: While specific advisees are not listed, Goldsby’s laboratory supports graduate students and postdocs in high-pressure geophysics and cryomaterials research. Ongoing projects include NSF-funded studies on ice deformation mechanisms and mantle rheology.
