I am a Research Officer with the Ventilation and Indoor Air Quality (VIAQ) group of the Construction Research Center at the National Research Council Canada (NRCC) in Ottawa. My research is centred on enhancing building resilience against climate change, in line with the Climate Resilient Built Environment (CRBE) initiative at NRCC. Specifically, I focus on energy-efficient and carbon-neutral solutions to alleviate the repercussions of heatwaves and wildfire smoke on indoor environment quality (IEQ) and occupant health. Furthermore, my endeavours also span to regulate indoor airborne transmission and enhance protection against respiratory infections, especially in the context of COVID-19 and the COVID-19, Ventilation for Control of Respiratory Infections, and Healthy Built Environment initiative at NRCC. Passionate about innovation, I actively seek collaborations with industry stakeholders, universities, and research institutions to unearth and implement pioneering technologies that address both the pressing and potential environmental challenges our buildings face today and in the future.

I earned my Ph.D. in Building Engineering from Concordia University, Montreal, and was privileged to be part of the Centre for Zero Energy Building Studies (CZEBS). During my doctoral studies, I also joined the Facade System and Products (FSP) group of NRCC, supporting projects under the Climate-Resilient Buildings and Core Public Infrastructure initiative.

During my Ph.D. study, I have been involved in multiple projects of different topics:

• Air curtain design and operation opitmization. Link>>, Link>>, Link>>
• Sub-scale modeling and Re-independent theory of urban aerodynamics. Link>>, Link>>
• Airflow managements of indoor growing farms. Link>>
• Energy efficiency and ventilation system optimiation of a road tunnel. Link>>
• Summertime building overheating assessment and mitigation during heatwaves. Link>>
• Weather data generation using Weather Research and Forecasing (WRF). Link>>, Link>>
• Statistical downscaling of high-resolution climate data for Canadian Cities. Link>>
• AMCA COVID White Paper on Un-ducted Fans: Air curtains, ceiling and circulating fans. Link>>
• Estimating and mitigating SARS-CoV-2 exposure risk in mechanically ventilated space.
