Professor Dr. David Goldsby

Biography

David L. Goldsby is a Professor and Department Chair in Earth and Environmental Sciences at the University of Pennsylvania. He specializes in mineral rock physics, focusing on the rheological behavior of Earth and planetary materials. As an experimental geophysicist, Goldsby applies theories and methods from materials science to better understand geophysical processes at large scales. His research involves conducting experiments under high confining pressures and ambient temperatures, as well as high temperatures for materials like olivine and ice. Goldsby's specific research interests include grain size-sensitive flow in materials and the creep behavior that involves grain boundary sliding. This flow behavior dominates at lower stresses compared to dislocation creep, impacting the rheological behavior of materials in natural environments, such as glaciers, icy satellites, and the interiors of Earth and other planets.
