Nuclear Oversight & AI Governance
Oversight • Compliance • Governance • Intelligent Systems
Independent Insight for Safety-Critical EnvironmentsI help nuclear organizations strengthen oversight, governance, and safety performance through modern standards and intelligent systems.With 20 years of experience inside OPG’s Nuclear Oversight function, I work at the intersection of safety, compliance, and AI governance.I specialize in identifying gaps, improving program documentation, and enabling leaders to make safer, smarter decisions.• CSA N286 / WANO PO&C compliance
• Program & project oversight excellence
• AI governance for safety-critical environments
About Me
—I’ve spent the last two decades inside Ontario Power Generation, working in one of the most demanding oversight environments in the world — nuclear. What started as a technical role gradually evolved into a passion for clarity, governance, and decision-making that keeps people safe.My work sits at the intersection of:
• safety
• compliance
• human performance
• intelligent systemsOver the years I’ve led and contributed to major oversight reviews, governance assessments, program documentation improvements, and safety-critical evaluations across complex projects and operations. I’m especially focused on helping teams see risks earlier, communicate better, and make smarter decisions with confidence.Today, I’m expanding my expertise into AI governance for safety-critical environments — exploring how intelligent tools can strengthen oversight, improve traceability, and support leaders in navigating increasing complexity.
Outside of work, I’m passionate about continuous learning, understanding how systems fail or succeed, and helping organizations build cultures where safety and integrity come first.
