This fully funded PhD position at Concordia University in Montreal focuses on transforming built and urban microclimates to advance resilience science for vulnerable populations in a decarbonized and electrified Canada. The project addresses the growing risks of urban heat and climate change, particularly for seniors and Indigenous communities, by leveraging sensors, artificial intelligence, and climate modeling to predict health impacts and inform city planning. The research aims to develop energy-efficient building upgrades and green infrastructure in areas most affected by extreme heat, supporting real-world projects such as Net-Zero neighborhoods and contributing to equitable, science-based climate policies. The successful candidate will join the Department of Building, Civil, and Environmental Engineering within the Gina Cody School of Engineering and Computer Science, working under the supervision of Professor Hua Ge. The role involves conducting field measurements and tests in both indoor and outdoor environments, designing and validating deep-retrofit measures for building envelopes and ventilation, and planning and executing indoor air quality (IAQ) and envelope diagnostics. The candidate will prototype and evaluate overheating mitigation strategies, such as radiative cooling, thermal storage/phase change materials, shading, and air handling unit upgrades, using advanced facilities like the NRC test house and Concordia’s Future Building Lab (FBL) and Smart Sustainable Engineering Centre (SSEC). Key responsibilities include building and calibrating hygrothermal and computational fluid dynamics (CFD) models to assess moisture and heat transport, evaluating the durability of envelope systems under extreme weather, and modeling the effects of green roofs, walls, and trees on thermal comfort and natural ventilation. The research will support validation and risk mapping for cities such as Montreal, Ottawa, and Toronto, and translate monitoring data into resilience design guidance for high-risk contexts, including First Nations housing and urban overheating zones. The candidate will also co-develop practical guidance and tools for home envelope and IAQ measures for older adults, support workshops and demonstrations, and simplify technical results for non-technical audiences. The position offers opportunities to contribute evidence to national code and standards development (NBCC, CSA, ASHRAE), draft test and assessment procedures, and co-author technical notes and briefs. The candidate will publish in peer-reviewed venues, present to stakeholders, and collaborate across interdisciplinary teams. The research environment is dynamic and supportive, bridging building engineering, urban microclimates, materials science, and policy, with strong encouragement for publications and presentations. Applicants must have a Master’s degree in a relevant engineering field, experience with simulation and modeling tools, hands-on experimental skills, familiarity with overheating mitigation and envelope durability, strong data analysis and technical writing abilities, and readiness for collaboration and respectful engagement with community stakeholders. The position provides a competitive stipend of 35,000 CAD per year for four years, plus additional support for research travel, conferences, and industry and community collaborations. Applications are accepted year-round and reviewed on a rolling basis.
