Dr. Reagle is a licensed professional mechanical engineer and certified fire and explosion investigator. He specializes in performing failure analysis and providing design support for problems involving thermal fluid flows, thermal energy release and sustainable energy systems.  Dr. Reagle is an expert in using IR thermography to understand complex ignition and heat transfer problems. 

At Exponent, he has inspected structure fires, involving kitchen appliances and various consumer products, and vehicles where carbon monoxide poisoning was suspected. He has conducted large scale battery risk assessments including cryogenic fault detection and fault recreation testing. He has conducted testing of respirators for asbestos filtration efficiency. He has sampled hazardous gas, such as methane and hydrogen released from the combustion of samples, to evaluate sensors and detection systems.  He has contributed to projects involving flammability testing and thermal evaluation of consumer products, design evaluation of gas burning appliances, investigation of vegetation and vehicle fires, assessing safety and fire risk in roll on-roll off cargo operations, and hazardous materials release from railroad tank cars.

Prior to joining Exponent, Dr. Reagle was an associate professor of Mechanical Engineering at George Mason University. As the first faculty hire for the program, he helped build the program through teaching and service. He has held a variety of temporary academic and industrial research positions focused on propulsion, power, and energy. His graduate research applied his expertise to heat transfer and aerodynamic characterization of turbomachinery hardware at transonic speeds and particulate laden flows at high temperatures.
