Jonathan D. Bray

Jonathan D. Bray is a Faculty Chair in Earthquake Engineering Excellence and a Distinguished Professor in the Department of Civil and Environmental Engineering at the University of California, Berkeley. His research interests include earthquake engineering, geotechnical engineering, physical and numerical modeling, and environmental geotechnics. Bray's work focuses on the seismic performance of earth structures, liquefaction, and ground failure effects on structures. He has authored numerous publications and has served as a consultant on engineering projects and peer review panels. Bray's research has been informed by observations from significant earthquakes and has contributed to the development of simplified procedures for seismic slope displacement and liquefaction-induced building settlement.

Jonathan D. Bray is a Distinguished Professor of Civil & Environmental Engineering at the University of California, Berkeley, specializing in geotechnical and earthquake engineering. His research focuses on understanding and mitigating the effects of earthquakes on soil and structures, including ground motion characterization, liquefaction susceptibility, and seismic-induced displacements. Bray's work addresses critical aspects of earthquake engineering, such as fault rupture propagation, seismic site response, and the behavior of soils under dynamic loading. His publications explore empirical relationships for frequency content parameters, simplified procedures for estimating earthquake-induced displacements, and the geotechnical impacts of major earthquakes, such as the 2011 Christchurch earthquake. His research contributes to the development of performance-based design methodologies and the assessment of liquefaction risks in fine-grained soils and landfills.
