A population framework for predicting the proportion of people infected by the far-field airborne transmission of SARS-CoV-2 indoors (2022)
Journal Article

The number of occupants in a space influences the risk of far-field airborne transmission of SARS-CoV-2 because the likelihood of having infectious and susceptible people both correlate with the number of occupants. This paper explores the relationsh... Read More about A population framework for predicting the proportion of people infected by the far-field airborne transmission of SARS-CoV-2 indoors.

PM2.5 exceedances and source appointment as inputs for an early warning system (2022)
Journal Article

Between June 2018 and April 2019, a sampling campaign was carried out to collect PM2.5, monitoring meteorological parameters and anthropogenic events in the Sartenejas Valley, Venezuela. We develop a logistic model for PM2.5 exceedances (≥ 12.5 µg m−... Read More about PM2.5 exceedances and source appointment as inputs for an early warning system.

Modelling uncertainty in the relative risk of exposure to the SARS-CoV-2 virus by airborne aerosol transmission in well mixed indoor air (2021)
Journal Article

We present a mathematical model and a statistical framework to estimate uncertainty in the number of SARS-CoV-2 genome copies deposited in the respiratory tract of a susceptible person, , over time in a well mixed indoor space. By relating the pre... Read More about Modelling uncertainty in the relative risk of exposure to the SARS-CoV-2 virus by airborne aerosol transmission in well mixed indoor air.

What we think we know about the aerodynamic performance of windows (2020)
Journal Article

© 2020 Natural ventilation is a low energy strategy used in many building types. Design approaches are mature but are dependent on variables with high uncertainty, such as the aerodynamic behaviour of purpose provided openings (PPOs), which need impr...
