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 build practical tools that turn complex process behavior into measurable, actionable information. I thrive on building innovative tools. From sensors to data-driven systems, my work bridges the gap between scientific research and industrial application.
I specialize in developing practical measurement tools for flotation systems, with a focus on gas dispersion, frother behaviour, bubble size, froth behavior, and process diagnostics. My work combines mineral processing expertise, sensor development, and industrial field experience to help operations better understand and optimize their flotation circuits.
