Expertise Description

I am experienced in the field of roadside safety engineering. While working at a prominent research institute in the field of transportation safety engineering, I assisted in constructing roadside and median safety features for the purpose of conducting standardized crash testing according to NCHRP Report 350 and MASH test protocols. I also documented some of those tests by recording observations, taking measurements of various forms of damage, and compiling technical reports. I also researched ditches, crash cushions, low-volume roads, trees, cable guardrail, W-beam guardrail, concrete median barriers, and temporary concrete barriers. I also investigated the fracture behavior of thin steel under dynamic loading conditions. I am familiar with dynamic and static component testing, computer simulation via LS-Dyna, and full-scale crash testing for Federal approval of highway safety appurtenances. I have also taught classes on elasticity, continuum mechanics, fracture mechanics, and LS-Dyna. I have also conducted a statistical analysis of the in-service performance of guardrail terminals. I have offered my services as a roadside safety engineering expert witness by providing consultations, courtroom testimony, and deposition.

Expert 506912 - TX

Expertise Description

I have more than 35 years of experience as a Mechanical Engineer with expertise in combustion, internal combustion engines, fuels, emissions, engine control systems, emissions control systems, and automotive engineering. I obtained my Bachelor's degree in Mechanical Engineering followed by three graduate degrees culminating in a PhD with a specialization in combustion. I joined as faculty of a Department of Mechanical Engineering where I established their combustion and engines research program. I have been involved in research in the area of combustion, engines, emissions, and alternative fuels for over 35 years. My research includes both experimental work and numerical modeling of both fundamental combustion processes and combustion within engines. My present research is focused primarily on the spark ignition process, modeling heavy-duty Diesel engines, and methods for improving fuel consumption for both light-duty and heavy-duty vehicles. I have over 20 years of expert witness experience with consultation, deposition, and courtroom testimony.
