Graduate Student Openings

Graduate students (MASc or PhD) with a background in heat transfer, thermodynamics, programming, energy systems, and/or building science/physics are needed to pursue research in the following topics. Please contact Prof. O’Brien if you have the above background and are interested in researching these topics. Co-supervision by another professor in CEE or another department (e.g., Mechanical and Aerospace Engineering) is also a possibility. The right candidates will be given the opportunity to work on important problems with significant impact on industry, the opportunity to work with industry partners, and competitive compensation.
