Dr. John Gallagher

Assistant Professor (Civil Struct & Env. Eng.)

Assistant Professor in Environmental Systems Modelling in the Department of Civil, Structural & Environmental Engineering. My research focuses on the delivery of innovative solutions to current environmental, energy and engineering challenges and adopting a circular economy approach in the life cycle of measurement, modelling and mitigation. My expertise includes the passive control of urban air pollution and building ventilation systems, delivering efficiency/offset/recovery solutions for the water-energy nexus, and promoting low-carbon and resource-efficient buildings or energy systems.

My research interests and expertise focuses upon the delivery of innovative solutions to current environmental and energy challenges. I aim to ensure that my results/solutions do not have consequential impacts by looking towards the future as well as examining results from the past. This approach is considered in my research of passive air pollution controls, low carbon and resource efficient system design and innovation in the delivery of technological solutions for energy efficient systems. I approach research problems using the 3M Model (Measurement, Modelling and Mitigation), and use my experience in life cycle assessment and the circular economy to generate conclusions without negative consequences.
