Biography
Dr Michaela Reay is a Postdoctoral Research Associate based in the Organic Geochemistry Unit in the School of Chemistry, University of Bristol. She is a biogeochemist, with expertise in stable isotope probing, and a keen interest in applying analytical chemistry to environmental questions. She completed her PhD at the University of Bristol in 2020, where she focused on using compound-specific 15N-stable isotope probing to elucidate microbial N cycling in grazed ecosystems. She subsequently moved to the University of Birmingham, working at the Birmingham Institute of Forest Research Free Air Carbon Enrichment experiment, elucidating the effect of increasing atmospheric carbon dioxide on nutrient cycling in mature forests. She returned to Bristol to work on the GCRF Plastic Legacy in Soil project and will focus on using mass spectrometry to quantify and trace microplastics and associated additives from agricultural plastics, alongside investigating the impacts on nutrient cycling under plastic mulch.
