Bringing more than 35 years of experience in fire protection engineering and fire safety science, his work focuses on fire dynamics, fire testing, and fire investigation, with globally recognized expertise in the measurement and analysis of heat release rates and fire behavior. His expertise includes development of fire safety engineering methods, fire resistance, fire testing, ignition phenomena, flame spread, heat release rate analysis, explosions, and fire modeling, as well as investigation of electrical fires, product failures, and hazardous material incidents. His work also encompasses furniture and plastics flammability, fire toxicity and corrosivity, spontaneous combustion, smoke production, and the application of fire science principles to origin-and-cause determinations.

Leadership in fire science research and consulting includes founding and directing a fire safety engineering and research organization dedicated to fire safety research, development, and forensic consulting. His prior work includes senior research and program leadership roles at a national laboratory, where he directed major initiatives in materials flammability, fire toxicity, test method development, upholstered furniture flammability, and building code fire safety requirements. His experience also includes development of fire test methodologies, evaluation of product performance, design of fire test apparatuses and instrumentation, and execution of full-scale and bench-scale fire testing programs across a wide range of materials and systems.

His professional distinctions include numerous prestigious national and international awards recognizing his contributions to fire safety science, including top honors from leading fire protection and engineering organizations for lifetime achievement, research excellence, and innovation in fire testing methodologies. He holds a doctoral degree in fire protection engineering, a master’s degree in structural engineering, and a bachelor’s degree in physics with a concentration in electrical engineering. His professional affiliations include fellowship in the Society of Fire Protection Engineers and active participation in organizations such as the National Fire Protection Association, ASTM International, the International Association of Fire Safety Science, and the International Association of Arson Investigators, along with leadership and long-standing service on multiple technical committees related to fire investigation standards, including NFPA 921.

His scholarly contributions include authorship of more than 400 technical papers and reports, as well as multiple landmark reference works in fire safety science, including major textbooks and handbooks addressing heat release, ignition phenomena, electrical fires and explosions, smoldering fires, and combustion product hazards. His work has been foundational in advancing the scientific understanding of fire behavior, combustion processes, and fire investigation methodologies. He has delivered hundreds of lectures and professional training programs, including specialized instruction for fire investigators on the application of fire science principles to origin-and-cause analysis.

He is widely recognized as a leading international authority in fire safety science, with seminal contributions to the field including the development of the large-scale oxygen consumption calorimeter and the cone calorimeter, which has become the primary global standard for bench-scale measurement of heat release rates and is used in laboratories worldwide. His work has directly informed and shaped numerous ASTM, ISO, NFPA, UL, and other international fire safety standards. He has also developed additional instrumentation and methodologies for evaluating fire toxicity, combustion behavior, and fire hazards, and has contributed to advances in fire modeling, ignition science, and performance-based fire safety engineering.
