Graduated from the University of York in 2013 and started a PhD under the supervision of Tamara Galloway and Charles Tyler in January 2014. Being a farmer by upbringing probably formed the roots of my interest in environmental issues, leading to this current research into the environmental implications of nanomaterials in aquatic sediments.

Broad research specialisms:

  • Ecology,
  • nano-toxicology
  • environmental regulation of chemicals.

Project Title: Ecotoxicology of manufactured nanomaterials: what factors govern bioaccumulation in sediment dwelling species?

Supervisors: Professor Tamara Galloway and Professor Charles Tyler

Funding Body: Guidenano

Project Description:
Nanomaterials are of increasing concern to prospective risk assessment for aquatic environments. Their rapidly accelerating use and lack of regulatory tools to monitor their use and disposal mean that it is of upmost importance that a sound understanding of their fate in the aquatic environment is reached, upon which future regulation can be based. This project aims to address an environmental compartment of particular concern, namely the benthos. An important gap in the literature is insufficient understanding of the factors, both biotic and abiotic, which influence the internalization and subsequent bioaccumulation of engineered nanomaterials within sediment dwelling species. This project focuses on these factors that will influence the bioavailability, distribution and biological effects of nanomaterials in sediment dwelling organisms utilizing commercially relevant nanoparticles available through the wider Guidenano project.
