Jonathan D. Bray

Jonathan D. Bray is the Faculty Chair in Earthquake Engineering Excellence and a Distinguished Professor of Civil and Environmental Engineering at the University of California, Berkeley. He is a globally recognized authority in earthquake and geotechnical engineering, with research spanning seismic performance of earth structures, liquefaction, ground failure, and earthquake fault rupture effects.

Education: Bray earned his Ph.D. in Geotechnical Engineering from UC Berkeley (1990), M.S. in Structural Engineering from Stanford University (1981), and B.S. from the United States Military Academy (1980).

Research Interests: His work focuses on earthquake engineering, geotechnical engineering, physical and numerical modeling, and environmental geotechnics. Key areas include seismic site response, liquefaction of soils, seismic slope stability, and post-earthquake reconnaissance.

Contributions: Bray has developed widely used procedures for seismic slope displacement and liquefaction-induced building settlement. He created the NSF-sponsored GEER Association to capture post-earthquake data. His work has influenced seismic design codes and practices globally.

Awards & Recognition: He is a member of the U.S. National Academy of Engineering and a Fellow of the American Society of Civil Engineers (ASCE). His accolades include the Seed Medal, Terzaghi Award, Ishihara Lecture, Peck Award, Joyner Lecture, Prakash Award, Huber Research Prize, Packard Foundation Fellowship, and the NSF Presidential Young Investigator Award.

Grants & Projects: Bray has led major projects funded by the NSF, California Energy Commission, U.S. Geological Survey, and Caltrans, totaling millions in research funding.

Advising & Mentorship: He has supervised over 30 Ph.D. students, significantly shaping the next generation of earthquake engineers.
