Summary
Dr Steven Campbell is a Marie Skłodowska Curie Research Fellow in the Environmental Research Group where he is part of the Aerosol Science Team. His research focuses on developing our understanding of the chemical composition of ambient aerosol particles; in particular, the chemistry of highly reactive particle components, seeking to understand their influence on aerosol particle composition and subsequently their impacts on human health.
He has developed and applied multiple acellular chemical methods to quantify reactive and therefore short-lived chemical species in aerosol particles. He has incorporated these methods into novel online instruments to quantify the oxidative potential (OP) of aerosol particles, a metric which is widely suggested to be indicative of particle toxicity, in real time. These methods allow robust, continuous quantification of particle OP with an unprecedented high time-resolution. He now utilises these methods in a range of laboratory-based studies, probing the fundamental chemical drivers of particle OP, and ambient field campaigns alongside ongoing established atmospheric pollution measurements, to determine the temporal variability of OP, and the sources potentially contributing to aerosol particle toxicity.
