Biography

I am a PhD student based in the Wolfson Atmospheric Chemistry Laboratories (WACL) at the University of York, working with Dr Jacqui Hamilton and Dr Andrew Rickard, investigating biogenic secondary organic aerosol (BSOA) species found in particulate matter in Beijing and Delhi. I previously completed my integrated master’s in chemistry at the University of York, working with Dr Jacqui Hamilton looking at the sources of BSOA in Beijing. I am from Plymouth, Devon and alongside my studies I enjoy walking, gaming and cooking. I also really enjoy travelling, trekking to Everest Base Camp when I was 16 really kick started my passion for the natural environment.

Project outline

This project aims to improve our understanding of the impact of natural emissions on particle pollution in cities. Exposure to poor air quality is the top environmental risk factor of premature mortality across the globe. Heart disease and strokes are the most common reasons for premature deaths from air pollution, with other factors including increased respiratory and cardiovascular disease and cancer. A recent paper predicted that biogenic emissions, especially isoprene dominates the production of secondary organic aerosol (SOA) in Beijing during summer. The relative importance of biogenic vs anthropogenic SOA is difficult to determine using bulk analytical techniques. We are using ultra high-resolution mass spectrometry to investigate the factors that control the oxidation and abundance of biogenic SOA (BSOA) and develop methods to estimate the total biogenic loading using source apportionment. This is done using an extensive mass spectral library of tracer molecules that can be used to chemically “fingerprint” specific volatile organic compound emissions/sources. Which has been built using a novel atmospheric simulation chamber, where a single VOC precursor can undergo atmospheric reactions in a controlled manner.
