Dr. Gingery is a principal engineer and Senior Fellow with Kleinfelder based in their San Diego, California office. He has a diverse background in geotechnical and earthquake engineering and has provided consulting services in the transportation, water/wastewater, energy, commercial/industrial and government sectors. In his role as Senior Fellow at Kleinfelder, Dr. Gingery serves as a company-wide technical resource for problem solving in geotechnical earthquake engineering and numerical modeling. Some of his recent work has included three dimensional nonlinear numerical modeling of fault rupture through large diameter cast-in-drilled-hole foundations; two-dimensional nonlinear dynamic analysis of embankments and retaining walls; site response for liquefaction sites; and settlement analysis of soft ground sites with complex stress history and loading. In addition to his consulting work, Dr. Gingery is active in research activities involving nonlinear site response and ground motions at liquefaction sites. He recently participated in the â€˜Prenolinâ€™ multi-year collaborative research program based in France that developed best practices and quantified epistemic uncertainties in nonlinear site response analysis. Dr. Gingery earned a B.S. in Civil Engineering from San Jose State University, a M.S. in Geotechnical Engineering from the University of California, Berkeley, and a Ph.D. in Geotechnical Earthquake Engineering from the University of California, San Diego. He is a registered Civil and Geotechnical Engineer in the State of California.
