Summary
👤
Senior🎓
Top SchoolCraig Weinschenk is a research engineer with 14 years of experience specializing in computational and experimental fire protection engineering, currently at Underwriters Laboratories in Baltimore. He combines deep expertise in heat transfer, combustion chemistry, CFD and fire dynamics with hands-on live-fire and bench-scale experimentation to validate and improve fire models. His sustained open-source contributions to the Fire Dynamics Simulator (FDS) project — including combustion model fixes, ODE solver enhancements, and verification test cases — reflect a rare blend of Fortran-based simulation development and experimental validation. Craig’s work spans practical firefighter protective-equipment testing and reconstruction applications, and he pursues advanced topics like moment-based uncertainty propagation to make fire simulations more reliable for decision-making.
