This project aims to develop validated models for aerosol transmission in public spaces and transportation modes by analyzing the effectiveness of different NPIs, including masks and HVAC interventions, to mitigate the transmission of infectious diseases.

Project Impact on the Emerging Infectious Disease Modelling (EIDM) Initiative
This project has been able to combine SIR and CFD modelling and include Machine Learning to advance the research further.
Implementation of the One Health Approach
Implementing the One Health approach has been crucial to taking a systematic lens to this research.
Focus Areas and Research Achievements
We are conducting research on how aerosols move within indoor environments to understand the risk of transmission of airborne diseases, such as COVID-19, and how we can improve the HVAC design to improve indoor air quality.Dr. Marina Freire-Gormaly, York University
Guided by the expertise of accomplished Master’s students—Arma Khan, an OGS recipient; Kishon Webb, recipient of an NSERC CGS-M, and Abu Raihan Ali—the team leverages cutting-edge Computational Fluid Dynamic modelling techniques with ANSYS FLUENT.
The figure (on the right) shows aerosol particles spread from an infected person in the middle of the classroom in the Bergeron Building towards the back of the classroom where the HVAC outlets are located. Ongoing research shown in the figure is from Arma Khan’s modelling of an infected person inside a classroom, which shows how the aerosol moves toward the back of the classroom. Master’s student Arma Khan conducted this research under Dr. Marina Freire-Gormaly’s supervision.
To learn more, listen to Kishon Webb’s conference presentation at the CSME Congress 2022 in Edmonton on modelling the molecular dynamics of the COVID-19 virus in humid outdoor environments.
