Expert Witness received his Ph.D. in civil engineering (Transportation/Pavement Engineering) from the University of Arkansas (1990), and received his M.S. in civil engineering (Construction Engineering and Management) from San Jose State University (1985), and B.S. degree in Civil Engineering from California State University, Sacramento (1982).
Expert Witness has over 27 years in professional engineering experience encompassing public agencies (Federal Highway Administration (FHWA) and the California Department of Transportation (Caltrans), academia and industry with over 200 technical publications. He taught at California State University and at National University from 1993 to 1999 various classes such as transportation and highway engineering including geometric design standards, traffic engineering and safety hazards as well as statistics. He taught university graduate and undergraduate students as well as advised graduate students through their research studies.
Expert Witness served as a principal investigator on multi-million dollar projects. While working for Caltrans from 1991 to 2010, he was involved at various high level engineering capacities such as being the Chief of Pavement Research, the QC/QA program manager, the chief of the Pavement Design and Rehabilitation and the chief of Pavement Preservation, and served as the Caltrans State Pavement Engineer. He directed Caltrans’ Pavement Program as a Division Chief and oversaw over 50,000 lane miles with a budget of over $200 million in pavement maintenance and over $500 million in pavement rehabilitation.
Expert Witness has been providing expert witness services, expert testimony and litigation support to attorneys and legal entities on cases related to accident reconstruction, analysis, design standards, construction specifications, guidelines, policies, public agency practices, transportation, roads, pavements, airports, materials, highway geometric design, drainage, asphalt, concrete, soil, repairs, maintenance, inspections, rehabilitation, construction quality control - quality assurance, construction claims, inspection, settlement, dispute resolution, pavement surface conditions such as friction, skid resistance, surface discontinuities, cracking, rutting, defects, potholes and roughness, failure investigations, forensic engineering, traffic, safety standards, construction work zone accidents, construction safety, safety operating procedures, roadside hazards, signage, sight distance requirements, ADA requirements, code violations, and engineering analysis.
Expert Witness’s education and experience demonstrates a wealth of engineering knowledge stretch in transportation and pavement analysis, design, rehabilitation, materials and construction in concrete, asphalt, soils, earth structures and foundations. As a recipient of many acknowledgements from the government and industry, Expert Witness has an impeccable reputation within the industry for his significant professional contributions. As an expert orator, he frequently shares his knowledge at major conferences. Professional AchievementsNational and International Leadership
• Envisioned and co-chaired the First International Pavement Preservation Conference in collaboration with Caltrans partners (industry, local agencies and FHWA). The conference drew over 300 attendees from many countries.
• Envisioned and established the California Pavement Preservation Center (CP2 Center). The Center became the focal point for innovation and promotion of pavement preservation.
• Envisioned and established the California Pavement Preservation Task Group (PPTG) in collaboration with Caltrans partners. The PPTG grew to 22 subtask groups with over 250 members.
• Envisioned and established the annual California Pavement Preservation Conference in collaboration with Caltrans partners. This annual conference started in 2004 with over 300 attendees every year.
• Championed and co-chaired the International Asphalt Rubber 2006 conference in California while working closely with industry. This conference started in 2000 with over 300 attendees every year.
