Joshua Swann, Ph.D.

Associate
Thermal Sciences
Bowie

Dr. Swann applies fire protection engineering, heat transfer, and fire dynamics principles to the analysis of active and passive building fire protection and life safety systems, material fire performance, and origin and cause investigation of residential, commercial, and industrial fires and explosions. Dr. Swann’s training and practical experience includes the design of automatic sprinkler systems, building life safety systems, code compliance of national, state, and local fire, building, and life safety standards, and engineering risk analyses. He has practical experience conducting laboratory experiments to evaluate material fire performance of construction materials utilizing both standardized and customized test methods.

Prior to joining Exponent, Dr. Swann conducted fire research at the University of Maryland in the Department of Fire Protection Engineering. Dr. Swann’s graduate research assistantship included the development, construction, and operation of the Controlled Atmosphere Pyrolysis Apparatus II (CAPA II) to perform gasification experiments on highly charring and intumescent polymeric construction materials. He subsequently derived and validated comprehensive pyrolysis models based on milligram-scale and gram-scale experimental data. This work was funded by the U.S. National Science Foundation.
