SPEAKER
Dr. Norman Abrahamson
Adjunct Professor, University of California, Berkeley and University of California, Davis
Dr. Abrahamson is an internationally-known expert in seismic hazard and risk analyses, with a focus on the practical application of engineering seismology to the development of deterministic and probabilistic seismic criteria for engineering design and evaluations of seismic risk. He has been involved in developing or reviewing design ground motions for hundreds of critical infrastructure projects around the world. He is an adjunct professor at UC Berkeley, and UC Davis, where he teaches a graduate course on seismic hazard analyses, development of design time histories, and seismic risk. His current research is focuses on non-ergodic ground-motion and fault rupture models, treatment of aleatory variability and epistemic uncertainty in site response, numerically efficient methods for evaluating seismic hazard for complex source and ground-motions, and decision making using hazard or risk estimates with large epistemic uncertainties.
