Robin K. McGuire, Ph.D., Founder and President of Risk Engineering Inc., was the 2009 Joyner Lecturer. He delivered his lecture at the SSA 2009 Annual Meeting in Monterey, California. McGuire holds degrees in structural engineering from MIT and Univ. of California, Berkeley. For 30 years he has been consulting in seismic hazard analysis, earthquake engineering, and the application of probabilistic methods to engineering problems. Dr. McGuire has also developed earthquake hazard software that is used around the world in engineering, insurance, risk management, government and research for seismic hazard estimation. Over one hundred of his papers and articles on these topics have been published in technical journals or as technical reports. Dr. McGuire is a past president of the Seismological Society of America, and has served on the Board of Directors for both the SSA and the Earthquake Engineering Research Institute. He has conducted seismic hazard analyses at sites of major engineering facilities at over 100 locations within the U.S. and at over 30 locations in foreign countries, in a range of technical environments. Dr. McGuire was elected to the National Academy of Engineering in 2007.
