Dr. Marr specializes in combustion science, turbulent mixing, and compressible fluid mechanics, and he applies this expertise to the investigation and prevention of fires and explosions. He is particularly interested in mixing applications in gas combustors, flares, and refineries. Dr. Marr has expertise in wide range of instrumentation and experimental techniques including laser diagnostics and emissions measurements that are applicable to thermal fluids and reacting flows.
Prior to joining Exponent, Dr. Marr was a research assistant in the Flowfield Imaging Laboratory at the University of Texas at Austin, where he contributed to a variety of projects. For his doctoral thesis, he worked on strategies to reduce emissions for combustion applications. His work involved a variety of measurement techniques ranging from advanced laser diagnostic techniques such as Stereoscopic Particle Imaging Velocimetry (PIV) and Planar Laser Induced Fluorescence (PLIF) to chemiluminescence imaging and pollutant species measurements. In addition to his combustion work, he also supported several other experimental projects in the area of high-speed compressible flows. For his Master’s thesis, he worked on developing bubble drag reduction methodologies for naval and watercraft applications.
