My primary research interests are in
geotechnical earthquake engineering, with emphases on seismic
soil-structure interaction, earthquake ground motion characterization, and seismic ground failure. My research has involved:
interpretation of earthquake strong motion data to gain insight into
soil-structure interaction effects, site effects, regional variations of
ground motions, and other effects; cyclic field testing of full-scale
foundation components including mat foundations, drilled shafts, and
bridge abutment walls; advanced dynamic testing of soils in the
laboratory; and case history studies of the seismic field performance of sites
in California, Taiwan, Turkey, Japan, Greece, Italy, and India. Results from my research group are widely utilized in engineering
practice, including ASCE-7 (for new structures), ASCE-41 (retrofit of existing structures) and additional guidelines documents for landslide risk and tall building design.
I am a registered P.E. in California and maintain an active consulting
practice to assist engineering firms and government agencies with
problems in geotechnical engineering and earthquake engineering.
Typical projects include probabilistic ground motion characterization,
ground failure hazard characterization (including landslides,
liquefaction, cyclic softening, and seismic compression), innovative
applications of field testing to evaluate critical material or system
characteristics, and expert witness testimony. |
