Dr. Walters' background is in chemical engineering, specializing in the areas of separations, process modeling, and process control. He has applied his expertise to a variety of pollution control technologies that are intended to prevent exposure to hazardous chemicals, mitigate environmental impacts, and comply with applicable regulations. He has specific project experience related to pollution control technologies that include scrubbers, thermal and catalytic oxidizers, baghouses, and liquid-liquid extractors. Dr. Walters leverages his knowledge of process systems to provide incident investigation and process safety consulting services, such as investigating fires, explosions, and chemical releases.

Dr. Walters frequently utilizes codes, industry standards, and recommended practices to perform hazard analyses, conduct technical assessments of novel systems or technologies, and evaluate claims made in civil litigation or international arbitrations. He has applied his knowledge of authoritative references to several clean energy systems; examples of such facilities include an anaerobic digester, a concentrating solar power plant, and a biomass boiler. Dr. Walters also has extensive experience with National Fire Protection Association (NFPA) standards related to combustible dust (e.g., NFPA 61, 652, and 654) and has used these standards to conduct dust hazard analyses (DHAs) at covered facilities.

Dr. Walters completed his Ph.D. at the University of Texas at Austin, where his dissertation focused on dynamic modeling and process control of carbon capture from power plants using amine scrubbing technology. Prior to joining Exponent, Dr. Walters worked as a software development engineer to provide process simulation capabilities for the gas treating and sulfur recovery industries.
