About the Project
This project is one of a number that are in competition for funding from the Red-ALERT CDT, hosted by the University of Bath for entry in September 2026.
Overview of the Research:
Project Idea:
There is a pressing demand for portable low-cost devices that enable rapid in situ determination of priority pollutants and biomarkers, many of which are electrochemically active and can be monitored utilising electrochemical techniques. However, measuring them with sensors selectively and at low levels in river waters are considerable challenges. This project will develop a prototype portable device for detecting the highly toxic organophosphate diazinon, at sensitivities commensurate with current freshwater Environmental Quality Standards. The device will integrate sample pre-concentration using functionalised magnetic beads, electrochemical sensing (e.g. voltametric methods) and data transmission to the cloud.
The project involves the following tasks:
• assessing the relative toxicity of diazinon to UK freshwater invertebrates relevant to RED ALERT study river catchments
• development of electrochemical sensors for diazinon;
• optimisation of the detection technique, automated analysis and data processing;
• development of analyte pre-concentration methods for enhanced limits of detection; • adapting the sensors for other electrochemically-active pollutant compounds;
• development of multiplexed sensor prototype device.
This project addresses a key feature of the RED ALERT CDT to develop sensors for detecting pollutants (here for one of major concern) in fast and low-cost ways for enabling wider and more efficient environmental monitoring practices.
Training Provided:
The interdisciplinary nature of the project means the student will get training, and develops skills, in a wide range of engineering systems, spanning electrochemical sensing, microfluidics, (bio)molecular immobilisation techniques, device development, as well as in ecotoxicology, data analysis and effective interdisciplinary communication.
Interdisciplinarity:
The project is inherently interdisciplinary, bringing in elements of electrochemistry, sensor development, basic electronics and ecotoxicology as well as consideration of translation of technology to applications. These will be merged and synergistically applied within the context of water sampling and monitoring for water pollution assessment.

Candidate Requirements:
Applicants should hold, or expect to receive, a First Class or good Upper Second-Class UK Honours degree (or the equivalent) in a relevant subject – e.g. biomedical engineering, electronic engineering, chemistry, biochemistry, etc. Academic qualifications are considered alongside significant relevant non-academic experience. A master’s level qualification would also be advantageous.
Equality, Diversity, and Inclusion:
We value a diverse research environment and aim to be an inclusive university, where difference is celebrated and respected. We welcome and encourage applications from under-represented groups.
If you have circumstances that you feel we should be aware of that have affected your educational attainment, then please feel free to tell us about it in your application form. The best way to do this is a short paragraph at the end of your personal statement.
Enquiries and Applications:
Formal applications should be submitted via the Red-ALERT CDT online application form prior to the closing date of this advert.
