Jonathan D. Bray, Professor of Geotechnical Engineering at UC Berkeley was selected as the 2012 Joyner Lecturer. He delivered his lecture at the SSA Annual Meeting in April 2012 in San Diego, CA. Dr. Bray was chosen because of his scientific and engineering research and exchange of information regarding liquefaction effects, the effects of surface fault rupture, and the safe siting and design of facilities near active faults. He has extensive experience serving at the interface of earthquake science and earthquake engineering. Dr. Bray is the chair of the NSF-sponsored Geo-Engineering Engineering Reconnaissance program, which has a goal to improve post-earthquake understanding and turn disaster into knowledge. He has published many papers on the interactions of buildings on or near surface faulting events. He has been recognized by several organizations for his work to improve seismic safety.
