About the Position
The University of Plymouth is inviting applications for a fully funded PhD in Marine Science. This opportunity focuses on developing next-generation sensors to monitor calcium and magnesium dynamics in coastal marine environments. Beginning in October 2026, the project is led by Dr Uwe Balthasar with additional supervision from Professor Simon Ussher and Dr Simon Whelan. The research centres on designing innovative screen-printed ion-selective electrodes capable of generating real-time Ca²⁺ and Mg²⁺ data, offering critical insight into how environmental change influences marine calcifying organisms. Working within the Sensor Technologies Research Group, the successful candidate will receive interdisciplinary training in chemical sensor fabrication, electrochemical analysis and coastal fieldwork in Plymouth Sound. This PhD aligns closely with the university’s strengths in marine science, geochemistry and environmental monitoring.
