Dr. Xiouris is a Mechanical Engineer that specializes in combustion and fire science, heat transfer, thermodynamics, and experimental design and testing. He performs failure analysis of industrial equipment, oil and gas systems, and consumer appliances. He has conducted cause and origin investigations of fires and explosions in residential structures and industrial facilities, involving natural gas and propane equipment, furnaces, ovens, cooking and heating appliances, and consumer products utilizing Lithium-ion batteries. Additional projects include burn injuries and carbon monoxide release and poisoning events.

Dr. Xiouris’ s project experience includes fire and heat transfer analysis pertaining to risk assessment and mitigation in industrial, and gas and electric utility facilities, including wildland fires. He is involved in fire and heat transfer testing, along with fire code compliance assessment.

Prior to joining Exponent, Dr. Xiouris completed his Ph.D. at the Combustion and Fuels Research Laboratory at the University of Southern California. He has extensive experience in quantifying propagation characteristics of flames under high pressure and temperature conditions, experimental design and instrumentation of combustion systems, experimental uncertainty quantification and error propagation, optics and laser diagnostics.
