I have over 25 years of expert witness experience with consultation, deposition, and courtroom testimony.

Areas of Expertise

Expert Witness

My expert witness experience includes concrete pavement surface friction loss and vehicle skidding problems, high pavement edge drop off related head on collision, freeway vehicle collision near a highway gore accident; concrete pavement premature cracking; motorcycle accident due to surface defects and potholes; bicycle accident due to the defect utility repair on a pavement surface; motorcycle accident due to a defect pavement repair; vehicle loss of control due to loose gravel; trip and fall accident in a park and ride facility; trip and fall accident on an ADA ramp with code violations, and vehicle accident related to maintenance work on the shoulder.

Consulting Experience

My consulting experience includes investigation of renature pavement distress, pavement surface condition survey, pre-construction reviews, construction quality control/quality assurance, forensic evaluation and analysis, construction training, specifications development, materials testing evaluations, asphalt pavement construction and evaluation, concrete pavement construction and evaluation, design/build projects, warranty specification, pavement maintenance, rehabilitation and design, construction management, pavement management systems, product evaluations, new technology evaluations, and life cycle cost analysis.

Relevant Experiences

I have extensive experience in estimating the cost of pavement strategies including slurry seals as I was in charge of a major transportation company’s pavement program.

I worked for over twenty years in pavement, design, analysis, construction, research, maintenance, repair and rehabilitation of pavements which include asphalt and concrete. Since my retirement, I have assisted attorneys on a number of cases related to safety and accidents, some of which involved trip and fall accidents.

This fits under my expertise. I have a Ph.D. in Transportation Engineering. I have expertise in parking lot design and layout in addition to working on similar cases.

I have extensive experience in cement concrete. I give training on the subject to contractors and staff on cement concrete. I have worked for in the industry for 20 years. You can refer me.

I have a PhD in transportation engineering with extensive experience in traffic engineering and highway design. I have worked on numerous cases involving bicycle accidents. This parked truck in the bike lane and behind a curve created a hazardous situation in what appears to be a sight distance problem.
