Dr. Chris Lautenberger |
Doctorate in Mechanical Engineering with concentration in combustion, University of California, Berkeley Chris Lautenberger received an MS in Fire Protection Engineering from WPI in 2002 with a thesis related to computational fluid dynamics modeling of flames, and a PhD in Mechanical Engineering from the University of California Berkeley in 2007 with a dissertation related to modeling how combustible solids burn. Before joining Reax Engineering in 2008, his work experience included building code consulting and performance-based design at Arup Fire (San Francisco, California) and Code Consultants, Inc. (St. Louis, Missouri), and fire litigation support as a freelance consultant. Dr. Lautenberger is a licensed Fire Protection Engineer in the State of California, making him one of the few fire experts that understands both real world fire protection engineering design and highly technical details of fire dynamics. Dr. Lautenberger's primary area of expertise is computer fire modeling. He is one of the leading fire experts in the rapidly growing field of fire growth modeling (sometimes called flame spread modeling or fire spread modeling) where computers are used to reconstruct fires or predict how a fire grow and spread. He has published several journal and conference papers on different aspects of fire modeling, including material property estimation for combustible solids, pyrolysis modeling, ignition of solid combustibles, and computational fluid dynamics modeling of soot formation/oxidation and flame radiation in laminar and turbulent diffusion flames. As part of his PhD dissertation, Dr. Lautenberger developed pioneering methods for material property estimation of combustible solids, one of the most challenging aspects of fire growth modeling. Dr. Lautenberger was recently invited to participate as a panel member, alongside several other international fire experts, at the Fire Spread Modeling Workshop held at the 9th International Symposium on Fire Safety Science, the largest and most prestigious international fire conference. |
Dr. David Rich |
Doctorate in Mechanical Engineering, University of California, Berkeley David Rich received a PhD in Mechanical Engineering from the University of California Berkeley in 2006, with a NASA sponsored dissertation related to ignition of solid fuels in the microgravity conditions found on spacecraft. Dr. Rich worked as a fire protection engineer at Arup Fire in San Francisco and is currently an adjunct professor at Santa Clara University (California) where he taught Fluid Mechanics (Fall 2008), is currently (Spring 2009) teaching a graduate class in combustion, and will (Summer 2009) teach a graduate class in fire dynamics. Dr. Rich is a fire expert with comprehensive experience in the fire testing laboratory and with the complex analysis and modeling tools in use today. Although he routinely uses modeling and analysis to answer questions related to fire litigation, his primary area of expertise is development of experimental platforms for the study of fire phenomena such as igniton and flame spread. Dr. Rich is an expert in infrared (IR) thermography, particle image velocimetry (PIV), planar laser induced fluorescence (PLIF), gas chromatography, Schlieren interferometry, mass loss rate measurement during pyrolysis and combustion, heat release rate measurement by oxygen consumption calorimetry, high speed video, and in-situ gas sampling. |

His fire litigation activities have involved many aspects of fires such as ignition of solid, liquid, and gaseous fuels; flame spread and fire spread; flammable liquid pool fire burning; self heating and spontaneous combustion; smoldering and transition from smolder to flaming; ignition of spot fires by embers and heated particles; wildland fires; vehicle fires; warehouse and industrial fires and explosions; laptop fires; smoke detector product liability; residential fires; fire reconstruction and modeling; and many other areas. It is this broad range of experience that makes Dr. Fernandez-Pello an effective fire expert witness across many areas of fire and combustion science. |
