Personal profile
Research interests
I am currently working as a PDRA in the Organic Geochemistry Unit at the University of Bristol, on the NERC-funded QUANTUM project which is part of the Freshwater Quality Programme coordinated by the University of Leeds. QUANTUM is seeking to quantify the impact of pastoral agriculture on UK freshwaters, with a view to informing future policy surrounding the protection of freshwater ecosystems. Within the project, my research focuses on exploring the sources and biogeochemical dynamics of organic pollutants from pastoral agriculture, and their subsequent impact on freshwater habitats. This includes determining chemical profiles for cattle and sheep excreta, and tracking these profiles through both terrestrial and freshwater environments via LC-MS/MS, DI-HRMS and GC-MS.
Prior to QUANTUM, I was completing my PhD in Physical Geography at the University of Bristol, titled "Investigating nutrient cycling, retention and bioavailability of effluents discharged from constructed wetlands: optimising wetland management to reduce emerging risks to freshwaters". My research sought to determine the suitability of constructed wetlands for the removal of nutrient pollution from wastewater effluent in the UK, and how systems can be optimised to limit pollution risk to freshwater ecosystems. I explored how carbon, nitrogen and phosphorus were biogeochemically cycled in a newly-constructed wetland, and how these processes could be creating emerging risks for adjacent freshwater environments. For this project, I worked in partnership with collaborators at the British Geological Survey and with a CASE partnership with Wessex Water.
