I am an Associate Research Officer at the Construction Research Center of the National Research Council Canada (NRCC). I recieved my Ph.D. degree in Building Engineering from Concordia University in Montreal. I worked with Prof. Leon Wang in the Centre for Zero Energy Building Studies (CZEBS) during my Ph.D. and I moved to Ottawa in October 2019 to be a student employee in the Facade System and Products (FSP) group of NRCC to work with Dr. Abhishek Gaur and Dr. Michael Lacasse on the Climate-Resilient Buildings and Core Public Infrastructure Initiative to investigate the climate change impacts on buildings and their mitigation strategies

My current study has been dedicated to the COVID-19, Ventilation for Control of Respiratory Infections, and Healthy Built Environment initiative at NRCC to work together with colleagues from Integrated Building Performance (IBP) and Indoor Air Quality (IAQ) groups. Through the collaboration with the government, public health agencies, health institutes, universities, and industry partners, we are seeking every possibility to combat this global indoor air crisis.

• I instructed a workshop of the CONTAM, the most well-known building multizone simulation program, for the eSim 2022 conference, Ottawa, ON, June 21st - 24th held by Carleton University. A word cloud was generated by the keywords in 482 papers found and reviewed in the field with their sizes weighted by frequencies.
