A geotechnical and engineering geology expert witness with more than 45 years of professional experience, this expert focuses on geological and seismic conditions affecting engineered structures, land development, and infrastructure projects. Their work addresses geotechnical engineering, engineering geology, earthquakes, subsidence, foundation distress, landslides, seismology, and grading-related geotechnical investigations. With more than 30 years of expert witness experience, the expert has provided consultation, deposition testimony, and courtroom testimony in matters involving geologic hazards, ground failure, and construction-related impacts on structures and infrastructure. Credentials include registration as a Professional Geologist and certification as an Engineering Geologist in the state of California. Educational background includes a Ph.D. in Engineering with a concentration in soil mechanics and earthquake engineering, along with graduate and undergraduate degrees in geology.

Professional work includes evaluation of seismic and geotechnical conditions influencing the performance of dams, pipelines, transmission systems, residential and commercial developments, and large infrastructure projects. Areas of analysis include slope stability, landslides, liquefaction, differential settlement, expansive soils, and ground deformation associated with seismic activity and fault movement. The expert has conducted regional seismotectonic reviews, developed seismic source models, and assessed earthquake ground motion and associated hazards affecting engineered facilities. Their forensic evaluations also address structural distress linked to subsidence, slope failure, improperly compacted fill, groundwater or hydrocarbon extraction, flooding, construction activity, and blasting. Leadership and professional service include roles as a commissioner with a state seismic safety commission and chair of a strong motion instrumentation advisory committee responsible for earthquake monitoring and seismic engineering considerations. The expert has also taught courses in geology and engineering geology and participated in technical studies related to earthquake hazards and ground deformation.
