Chris is interested in controlling biological wastewater treatment plants, waste-incinerators for power generation, organic Rankine cycles (for turning waste-heat into electricity), and wind turbines.

Research into biological wastewater treatment control was funded by the City of Calgary and Mitacs internships.

Research into organic Rankine cycle control was funded by local industry with a matching NSERC Collaborative Research and Development Grant.

Here are links to some of the group's publications in process control applied to green technologies.
