Apply for this 4-year funded PhD studentship to develop new air quality monitoring technologies for aerosols using experiments and simulations.
Fine particulate matter is associated with health risks, and recent research has also demonstrated its negative effects in other areas, such as the degradation of cultural heritage. However, the existing technologies to monitor aerosols are expensive and therefore not used widely to assess risks and in routine monitoring. This PhD project will develop the fundamental research needed to produce a passive dosimeter for particulate matter concentration, able to offer measurements of airborne concentrations of PM with an extremely low cost and no power consumption.
The device researched by the PhD student will enable data collection in an unprecedented rate, allowing mapping of pollutant exposure indoors and outdoors with high spatial resolution and more precision than current optical low-cost meters. However, these advantages are paired with drawbacks that need to be evaluated quantitatively: the accuracy and detection limits are likely to be a function of particle size, and the exposure times a function of concentration. The data obtained from these dosimeters will be optimal for the validation of dispersion models, such as computational fluid dynamics models. The outputs of this project will support research on exposure to pollutants in spaces such as schools, public spaces, museums, and residential buildings.
The overall aim of this PhD is to design, test and evaluate in real environments a dosimeter device that can offer reliable measurements of aerosol concentration. This research will require a combination of laboratory experiments, simulations, and field tests. More specifically the PhD would aim to:
- Develop a prototype dosimeter and calibrate it using environmental chamber experiments
- Use simulations to optimise the design parameters of the dosimeter
- Collect aerosol concentration measurements in indoor spaces using the developed technology in co-location with other methods
- Validate this approach and deploy it in wider field studies, potentially including comparison of the measurements with predictions of aerosol dispersion models
Applicants should meet the UCL Institute of Sustainable Heritage PhD programme requirements
A minimum of an upper second-class UK Bachelor's degree and a Master's degree, or an overseas qualification of an equivalent standard, in a relevant subject, is essential. Exceptionally: where applicants have other suitable research or professional experience, they may be admitted without a Master's degree; or where applicants have a lower second-class UK Honours Bachelor's degree (2:2) (or equivalent) they must possess a relevant Master's degree to be admitted.
All applicants must also meet the minimum language requirements of UCL.
