A mechanical engineering expert specializing in firearms design and mechanical systems analysis, he has more than 20 years of experience in advanced product development and engineering evaluation. The expert offers expert witness services involving consultation and applies technical knowledge of mechanical design, materials selection, manufacturing processes, testing, and production implementation to evaluate engineering issues. Professional work has included serving as a principal engineer responsible for designing, analyzing, and testing new commercial firearm products, managing technical requirements from concept through production, and developing components using machining, casting, metal injection molding, powder metallurgy, stampings, and injection molding processes. His technical expertise includes 3D CAD modeling using SolidWorks, geometric dimensioning and tolerancing, finite element analysis using ANSYS, and application of DFMEA, DFA, DFM, and Six Sigma design methodologies. Experience also includes development of detailed testing plans for functionality, durability, and safety, specification of materials and manufacturing processes for metal and synthetic components, and troubleshooting using analytical and high-speed diagnostic tools. He has served as lead designer or co-designer on multiple commercial firearm platforms and holds six U.S. patents involving fire control mechanisms, bolt assemblies, gas-operated piston systems, and electronically controlled firearm technologies.
