Charles Tom Kirbo M.S., EIT

Charles “Tom” Kirbo joined Protection Engineering Consultants, LLC (PEC) as an Associate Engineer in October of 2023. He obtained his Bachelor’s Degree in Civil Engineering from Texas A&M University in 2015 and his Master’s Degree in Civil Engineering from the University of Oklahoma in 2020. Before joining PEC, Tom was an Officer in the U.S. Air Force from 2016 to 2021. He worked as a Cyber Warfare Officer and helped develop communications systems that directly supported the warfighter. Tom completed three deployments to Afghanistan, multiple locations in Africa, and to Saudi Arabia. After being honorably discharged, he worked for BakerRisk as a structural engineer. While at BakerRisk, Tom completed numerous blast-resistant designs, internal detonation research, and on-site surveying of petrochemical facilities. He used a combination of single-degree-of-freedom analysis (SDOF), finite element analysis (FEA), and computer programming to dramatically increase design workflow efficiency.

Tom will be supporting the Applied Research group at PEC, where he’ll contribute to design and R&D efforts associated with explosives safety, protective design, and advanced analysis for extreme loading conditions.

Stephen Bratz, P.E.

Stephen joined Protection Engineering Consultants (PEC) in April of 2019. He holds a Master of Science degree in Structural Engineering from the University of Texas at San Antonio, where he researched the effects of welding on high mast illumination poles using the Abaqus Welding Interface (AWI) in his thesis. He also earned a Bachelor of Science degree in Physics from Texas Lutheran University.

Stephen provides support for design projects for blast and impact resistance of structures and glazing systems. In addition, he supports research efforts focused on the response of structures and construction materials subjected to blast loading and other extreme events. He has experience with MATLAB and various finite element software tools such as Abaqus and SAP2000.

Stephen will be supporting PEC and our clients on both research and design efforts, and can be contacted at 512-380-1988 x325 or
