Dr. Utiskul applies his knowledge of fire protection engineering, heat transfer, and fire dynamics principles to the analysis of building fire protection and life safety systems, the evaluation of materials, fire performance, the study of fire development and smoke movement within structures, and the origin and cause investigation of fires and explosions. He specializes in the design, installation, and testing of active and passive building fire protection systems, including automatic fire suppression systems, smoke management systems, automatic fire alarm and detection systems, and structural fire protection systems. With his experience in the application of various model codes, Dr. Utiskul provides consultation and analysis on complex issues related to building, fire, and life safety codes for high-risk occupancies. Dr. Utiskul also specializes in fire and smoke modeling, a skill set he has proficiently utilized in smoke control system designs and performance-based fire safety analysis as part of his code consulting services. Having conducted numerous fire tests, Dr. Utiskul also evaluates the fire safety performance of construction materials, consumer products, and household appliances based on standardized and uniquely tailored situational test methods.

Dr. Utiskul has extensive experience in fire origin and cause investigations for various types of occupancies ranging from small residential homes to high-rise buildings as well as large warehouses. He is also well-versed in utilizing fire and smoke modeling to examine smoke and fire propagation in support of fire origin and cause determination.
Dr. Utiskul's past research has focused on fully-developed compartment fires aiming at development of a model that can predict the compartment fire fuel mass loss rate, gas temperature, and specie mass fraction for any fuel, scale, and ventilation. The developed one-zone model has incorporated the fuel response to flame and its surroundings, which are essential to predict the true fuel mass loss rate in compartment fires. Dr. Utiskul performed small and mid-scale compartment fire tests to characterize the burning behavior in various ventilation conditions. Through his study, justification for a one-zone model and a near-vent mixing algorithm has been established. Dr. Utiskul also has expertise with scale modeling and generalizations of the experimental data to show the dependency of interested variables on governing factors.

In addition to his specialty in thermal sciences, Dr. Utiskul also applies his background in civil and transportation engineering to the reconstruction of transportation related accidents and the safety analysis of transportation system designs and constructions. He has investigated several major accidents and failures and has conducted reconstruction of accidents involving motor vehicles, rail transport vehicles, trains, and railroad maintenance equipment. Dr. Utiskul’s experience in civil and transportation engineering also extends to the safety analysis of railroad equipment and operations, traffic engineering designs, and operations of powered industrial equipment. He provides consultation on the use of traffic control devices as well as the analysis of accident database supportive of the accident investigations. Combining his expertise in fire investigation and accident reconstruction, Dr. Utiskul has investigated fire incidents involving vehicles and railroad equipment to determine the fire origin and cause in relation to the safety analysis of transportation system designs and constructions.

Prior to joining Exponent, Dr. Utiskul served as a Fire Engineer for a large international engineering consulting firm where he provided building code and fire engineering consulting services for domestic and international projects including: a high-rise casino resort with an area of greater than 10 million sq. ft. in Macau SAR, a multi-use development building in Abu Dhabi, and a number of multiple mixed-use high-rise buildings in southern California. He was involved in the development of fire protection and life safety strategy of buildings with a wide range of occupancy types and project size. He was also in charge of conducting plan reviews and routine inspections for egress strategy, automatic fire sprinkler systems, and automatic fire alarm and detection systems at a large multi-use hotel/casino project.
