Dr. Garner applies his expertise as a mechanical engineer to the scientific investigation and prevention of accidents. Dr. Garner specializes in the investigation and analysis of complex incidents, both domestically and internationally, involving fires, explosions, and failures of combustion and mechanical systems. These investigations have involved flammable petroleum products, combustible dusts, consumer products, residential appliances, industrial heating and fluid handling systems, pneumatic and hydraulic systems, as well as turbine equipment power generation facilities. Additionally, as a retired NCAA Division 1 gymnast, Dr. Garner has investigated and opined on various issues related to gymnastics equipment and trampolines.

Dr. Garner’s project experience includes the investigation of fires, explosions, and failures of various types of pumps, compressors and high pressure or vacuum systems, hydraulic systems, agricultural product conveyer systems, consumer products, residential and industrial burner systems, and gas turbine engines. He has also advised clients as they navigate product liability issues involving numerous different consumer goods and electronic components. Dr. Garner is active in the field of combustion safety and he sits as a principal voting member on NFPA 37 – Standard for the Installation and Use of Stationary Combustion Engines and Gas Turbines. Dr. Garner applies his investigation experience to the prevention of failures through the application of product safety and product liability methodologies, as well as process safety through hazard and risk analysis.

Prior to joining Exponent, Dr. Garner developed next generation aviation propulsion systems, including partial premixed lean burning combustors for gas turbine engines (jet engines), at General Electric. During his time at GE-Aviation, he routinely designed and tested jet engine combustors and combustor components as well as performed root cause analyses on failed hardware and tests.

Dr. Garner earned his doctorate in Mechanical Engineering at the University of Illinois at Chicago. His doctoral thesis focused on fuel rich bio-diesel combustion pollutant emission combustion kinetics, specifically NOx production pathways and precursors. His doctoral work was comprised of both theoretical and experimental studies employing a very high pressure and high vacuum experimental shock tube apparatus.
