Transforming complex problems into practical solutions
Mark Lepage, Ph.D.
I am driven by technology, innovation, and real-world impact.
Grounded in mineral processing and flotation, I develop practical tools that turn complex process behaviour into measurable, actionable insight. My work spans sensors, data-driven systems, and process analytics, with a focus on bridging the gap between scientific research and real-world industrial application.
I am most energized by building innovative solutions that make complex systems easier to understand, measure, and improve.
