My research interest is on air quality with a specific focus on particulate matter and how both natural and anthropogenic sources influence earth processes and result in polluted air. I investigate the emission, transport and deposition of atmospheric particulate matter and its influence on air quality, the environment and people. I am interested in urban and mining affected areas and landscape change including soil formation and degradation. I use remote sensing and ground based observational data and explore connections that can be made between these data sets to improve how we measure, model and manage air quality. I am interested in developing and implementing affordable and locally relevant methods for observational data collection, which includes low-cost sensors, exploring citizen science and community monitoring methods.
