Summary
👤
Senior🎓
Top SchoolLeon Starr is an MBSE expert and executable modeler with over three decades of hands-on experience translating fuzzy requirements into platform-independent, production-ready models for safety-critical and embedded systems. As founder of Model Integration LLC and former MBSE lead at Toyota Research Institute, he has guided global teams in building executable UML and model-driven code generation for autonomous driving, avionics, medical devices, and defense systems. He is the lead author of Models to Code (Apress, 2017) and has a longstanding track record of teaching, mentoring, and embedding with clients like Saab, Ericsson, and St. Jude to deliver high-assurance behavior through early simulation. Leon specializes in separating business/science logic from implementation to enable early system validation, rapid platform migration, and reliable code generation under tight concurrency and resource constraints. Based in Oakland, he continues to write and speak on practical MBSE, often revealing pragmatic process fixes learned from decades of rescuing messy models and delivering real products. An early adopter of model-driven engineering, he still keeps hand-drawn class/state models from the pre-UML era as a reminder of how far modeling practice has evolved.
