About this position
PhD opportunity at Heriot-Watt University in particle-toxicant interactions, ecotoxicology, environmental chemistry, and mangrove wetland ecology.
This project investigates how particles influence toxicant bioavailability, transformation, and toxicity in a tropical estuarine amphipod model (Parhyale hawaiensis) from mangrove wetlands. The work sits within the NERC-funded ECOWILD Centre for Doctoral Training and combines environmental toxicology, analytical chemistry, marine sciences, hydrology, and environmental biology to address pollution impacts in threatened mangrove ecosystems.
The supervisory team includes Theodore Henry (Heriot-Watt University), Teresa Fernandes (Heriot-Watt University), Alistair Boxall (University of York), Gisela Umbuzeiro (University of Campinas), and stakeholder supervisor Isabella Gosetto (JNCC). The project uses purpose-built particle-toxicant dispersion chambers and established field collaborations to study how salinity changes and particle associations affect toxicant behaviour in estuarine and mangrove environments.
Funding: full scholarship for Home students, covering tuition and a UKRI-level stipend (£21,805 in 2026-27) for 44 months. International applicants may apply, but successful candidates must provide co-funding for the international fee difference.
Eligibility: applicants should normally hold a first or upper second-class honours degree or equivalent in a relevant subject, and preferably a relevant Master’s degree or similar experience. Overseas candidates must meet English language requirements unless exempt under UK guidance.
Deadline: midnight BST on Tuesday 13 October 2026. Interviews are expected on 27 October 2026, with a January 2027 start.
