I am currently a Postdoctoral Research Officer in Environmental Science, working alongside Prof Davey Jones and Prof Dave Chadwick. My current areas of research include: 

1. Exploring soil nutrient cycling (e.g., C and P) and its impact on microbial ecology (e.g., carbon use efficiency) in dryland (e.g., Atacama desert, Australian soils) ecosystems.
2. Understanding long-term microplastic pollution and the degradation of plastic additives (e.g., DEHP and DBP) in soil.
3. Identifying critical 'tipping points' in soils subjected to extreme heat-stress events.
4. Wildfire soil ecology and strategies (e.g., fire retardants) to enhance resilience. 
5. The environmental impact of biosolid derived biochar (e.g., heavy metals, microplastics, antimicrobial resistance genes (AMRs), PFAS).
6. Lowland grassland management and sustainable livestock production. 

Alongside my postdoctoral research, I regularly supervise students conducting radiolabelled (e.g., ¹⁴C, ³³P and ³⁵S) and non-radiolabelled experiments. I am available for external collaborations to establish new projects. 

My PhD research was based on the exploring the agronomic and environmental benefits of grazing multispecies 'herbal' leys on lowland sheep production. The results of this research have been published open-access in Agriculture, Ecosystems and Environment. 

Supervisors:

Prof Davey Jones & Prof Dave Chadwick

• PhD: Exploring the agronomic and environmental effects of herbal leys on lowland sheep production
  2019–2024
• BSc: BSc (Hons) Geography
  2015–2018

Research Interests:

• Soil biogeochemistry.
• Microplastic pollution. 
• Extreme weather events (e.g., flooding, heat-stress).
• Wildfires.
• Herb- and legume-rich multispecies 'herbal' leys.
• Livestock productivity and health.
• Sustainable agricultural intensification.

Current Research:

As a Postdoctoral Research Officer in Environmental Science, I am responsible for a diverse portfolio of biogeochemistry projects exploring nutrient cycling and plant-soil-microbial interactions in a broad spectrum of global soils. I work closely with Prof Davey Jones and Prof Dave Chadwick to create and deliver new research ideas, primarily using radioisotope (¹⁴C, ³³P and ³⁵S) tracing techniques. Our current focus is to explore how a wide range of stress events (e.g., extreme temperatures, wildfires, salinity), contaminants (e.g., microplastics, PFAS), and bioamendments (e.g., biosolid derived biochar) affect soil biogeochemistry and microbial activity. 

In this role we have scope to develop new external collaborations, please get in contact if you are interested. 

PhD Research:

PhD thesis title: Exploring the agronomic and environmental effects of herbal leys on lowland sheep production

During my PhD project, I developed a comprehensive 2-year, 2-ha split-field experiment at Bangor University's Henfaes Research Centre that closely aligned with the aims of the wider BBSRC-SARIC research project (BB/R021716/1). My PhD project utilised Welsh mountain lambs (Ovis aries) grazing either a herb- and legume-rich multispecies 'herbal' ley or a conventional grass-clover ley to assess the impacts on soil biogeochemistry (e.g., C and N cycling), greenhouse gas emissions (e.g., N₂O) and ammonia (NH₃) volatilisation, soil structure (e.g., porosity using X-ray μCT), livestock excreta composition (e.g., urine-N), livestock productivity (e.g., liveweight gain) and health (e.g., gastrointestinal parasite burden, blood biomarkers), and sward productivity (e.g., macro- and micronutrient content). 

Previous Research Projects:

I have previously worked with Prof Daniel Murphy at the University of Western Australia on the Soils Quality project, funded by the GRDC (Grains Research and Development Corporation) on an Australian national soil quality project. Using radioisotopes (¹⁴C), we investigated microbial carbon use efficiency (CUE) of 970 agricultural soils taken from across Western Australia to determine the relationship between soil pH, cations (e.g., Al³⁺), and CUE.

Similarly, I was also a Research Support Technician on an industry funded project investigating the uptake and transport of commerical foliar applied phosphorus fertilisers in hydroponically grown wheat (Triticum aestivum) using radioisotope tracing techniques (³³P). 

BSc dissertation:

BSc thesis title: Upland-N₂O emissions: Investigating spatial differences in urine-patch N₂O emissions.

Achieved the School of Environment, Natural Resources and Geography (SENRGy - now School of Natural Sciences) award for 'Best Undergraduate Project' for the 2018 cohort.

For my undergraduate thesis, I produced an incubation study based on the NERC funded Uplands-N₂O project, led by PI Prof Dave Chadwick. I investigated urine-patch N₂O emissions from artificial sheep urine applied to acid grassland “island” and peat cores taken from the uplands of North Wales to generate a 41-day IPCC upland specific emission factor.
