Professional Experiences

My professional experience includes over 30 years of product and process development engineering, in many industries. The companies I have worked for include a major OEM automaker, a Tier 1 automotive stamping supplier, a class 8 truck suspension system supplier, and an OEM coach, bus and RV manufacturer. My responsibilities included design engineering, senior project engineer, manufacturing liaison engineer, program management, engineering manager, engineering director, program management director, and supply change management. I have been in the forensic engineering field since 2010 and hold two U.S. Patents.

Relevant Experiences

I have a strong trucking engineering background that includes product design and performance related investigations. While leading an advanced engineering team at a major tour bus manufacturer, we pursued various passenger door design options. While doing so, I also had to be aware of any regulations related to safety and performance. Several of my cases have required NHTSA, FMCSA, and specific state vehicle code research and comprehension. I also have direct experience with several school bus manufacturers.

I have a few years of experience with motorhomes and RVs, and have worked with a few of the manufacturers and suppliers. I have performed numerous vehicle inspections for various reasons since I have been consulting.

I am familiar with welding equipment, from manual mig and tig welders, to fully automatic robotic systems. I have both product design and manufacturing process, involving welding. It appears that Praxair welders utilize another manufacturers water cooler system (Miller), but maybe the specific model will shed more information.

I do have direct wind turbine experience since consulting. I have had two cases of failure of the equipment that I investigated. Both systems were made by Vestas. I believe I reviewed some information from GE at the time also.

I do have past experience with wind turbines, and investigating performance related issues. This description seems to indicate the overall structure was not designed to meet the stiffness specifications, or different than what was expected. I am confident I can review the available information and opine on the design.

I can definitely help with the accident reconstruction and perception time analysis. I have investigated and opined on many cases involving accidents of this nature. I have also utilized industry research and published papers for normal perception and reaction times, and then compared this information to the specific incident. I look forward to learning more about this case and the additional information for the conflict check.

I have been involved in several firearm tests and evaluations since consulting, and have an active plaintiffs case involving an accidental discharge with a rifle.  I have not been directly involved in bow equipment in the past, but I am quite familiar with design and performance issues, and customer expectations.  We also have our director of field services who is an avid hunter, and uses similar equipment.  His support on this investigation may also be utilized.

I have limited experience with Detroit Diesel engines but mainly for performing data downloads after accidents.

I have investigated a few crane incidents in the past. I have a current one that is still active. In addition to my mechanical engineering background that allows me to evaluate cranes for performance and structural issues, I also have a strong background in materials engineering. I have also reviewed and opined on OSHA standards and regulations as it relates to accidents. My previous crane investigations involved operator and coworkers actions, crane and boom structural failure analysis, and crane performance.

I have the mechanical engineering and vehicle level experience to investigate the client. I have investigated other boom lift and crane cases and have utilized and am familiar with the applicable CFR and ANSI/ASME standards.

I have training and experience in Energy capacity and calculations.

I have experience with patent cases, for both patent holders and alleged infringing companies.
