Ph.D.-level civil and transportation engineering expert witness with more than 27 years of professional experience and over 25 years of expert witness involvement, this professional provides technical analysis in matters involving highway and transportation engineering, pavement design and rehabilitation, traffic engineering, and construction-related disputes. Licensed as a Professional Engineer in California, the expert has provided consultation, deposition testimony, and courtroom testimony in cases concerning accident reconstruction, roadway surface defects, highway geometric design, construction quality control and assurance, public agency standards, and compliance with engineering specifications and safety codes.

The expert’s transportation and traffic engineering work encompasses highway alignment and geometric standards, sight distance analysis, curvature and superelevation criteria, braking distance evaluation, roadside hazards, guardrail systems, work zone safety, detour signage, ADA compliance, and driver behavior considerations. Experience includes evaluation of roadway surface characteristics such as friction, skid resistance, roughness, raveling, cracking, rutting, potholes, and loose aggregate, as well as analysis of motorcycle dynamics in relation to highway defects. The expert has assessed highway maintenance standards, safety operating procedures, and public agency manuals in disputes involving roadway design, maintenance, and construction practices.

In the area of pavement and materials engineering, the expert has directed and performed investigations involving asphalt and concrete pavement systems, soil and aggregate materials, geotechnical standards, drainage design, moisture intrusion, and failure analysis. Prior leadership roles include President of an engineering consulting firm and Division Chief and State Pavement Engineer for a state transportation agency, where responsibilities included oversight of large-scale pavement maintenance and rehabilitation programs and development of technical advisory guidance adopted at the state and national levels. The expert has led multi-million-dollar research and implementation initiatives, including long-life pavement programs and quality assurance systems.

The expert has been retained in litigation involving highway accidents, construction work zone incidents, pavement failures, construction defects, contract disputes, damage assessment, and forensic engineering investigations. Engagements have addressed compliance with design standards, engineering policies, materials specifications, construction claims, settlement analysis, and dispute resolution. The expert holds a Ph.D. in Civil Engineering with specialization in Transportation and Pavement Engineering, along with master’s and bachelor’s degrees in Civil Engineering, and maintains active licensure as a Professional Engineer. Through combined expertise in transportation systems, pavement materials, safety standards, and public agency practices, this expert provides technical evaluation in complex infrastructure and roadway-related litigation.
