Mr. Megerle performs analyses of process upsets and incidents in the chemical industry and investigates fires and explosions in residential and industrial settings. Further, Mr. Megerle routinely performs root cause analyses of product failures resulting in over-heating of consumer products and electronics with an emphasis on battery-operated equipment. His experience includes the study of chemical reactivity and testing of combustion behavior of materials, sampling of emissions and chemical substances, custom-designed testing to assess consumer device performance and safety, examination of consumer product failures and assessment of personal injury exposure, technical support in consumer product recall matters, and analyses of vehicle and structure fires. Prior to joining Exponent, Mr. Megerle worked as a visiting scientist at the Combustion Research Facility at Sandia National Laboratories in Livermore, California. His research employed laser diagnostics in internal combustion engines to advance the understanding of droplet and gas interaction in an effort to enhance fuel efficiency and reduce emissions. He has also performed research at the Sloan Automotive Laboratory at the Massachusetts Institute of Technology investigating the effectiveness of chemical inhibitors in a laminar diffusion flame under subatmospheric operating conditions.
