About Me Publications

I have 20 years of consulting and research experience in the fields of seismic hazard, geologic site characterization, and engineering geology. Much of my research and applied project experience relates to the evaluation of seismic hazards for regional lifeline systems and critical facilities such as gas transmission pipelines, electric transmission corridors and dams. I have been a Principal or co-Principal Investigator on six research projects sponsored by the California Energy Commission, United States Geological Survey’s National Earthquake Hazard Reduction Program, the National Science Foundation, and the Geological Society of America.
I specialize in active tectonics, paleoseismology, tectonic geomorphology, and Quaternary geochronology. I have applied my expertise for seismic hazard investigations on infrastructure projects, such as onshore and offshore pipelines, bridges, highways, tunnels, nuclear power plants, and dam projects for seismic source characterizations and system-wide vulnerability assessments.
