About the Partnership

Natural Environment Research Council funded RED ALERT Centre for Doctoral Training NERC Centre for Doctoral Training in Real-Time Digital Water-Based Systems (RED-ALERT CDT)  will provide training in water-based early warning systems for environmental and public health protection focused around 4 UK and 3 international Living Labs aimed to provide the in-depth knowledge and enable a step-change in managing environmental and public health.

This project is one of a number that are in competition for funding from the NERC Centre for Doctoral Training in Real-Time Digital Water-Based Systems for Environmental Health Protection (RED ALERT CDT).  The NERC RED ALERT CDT consists the University of Bath, Bangor University, Cardiff University and the University of Exeter plus the UK Centre for Ecology and Hydrology.  RED-ALERT CDT’s vision is to train and empower a new generation of leaders to transform how we manage aquatic   environmental health via Real-Time Digital Water-Based Systems.

For eligible successful applicants, the studentship comprises:

• A stipend for 3.5 years (£19,237 p.a. for 2024-25) in line with UK Research and Innovation rates
• Payment of university tuition fee;
• A research budget of £11,000 for conferences, lab, field and research expenses;

Project Background:

 Currently, quantification of dissolved metal pollutants in watercourses is hugely variable in convenience, speed and data quality. For many metals, accurate results are only achieved by slow and labour-intensive sampling and lab-based analysis. To address this unmet need, this project will develop colourimetric sensing devices that can remain submerged in water and provide frequent, automated measurements of specific metal cation concentrations. Sensors will be based upon lab-synthesised organic molecules that undergo colour change upon exposure to a specific metal, immobilised on a transparent surface to prevent them being washed away, whilst enabling optical measurement to take place to quantify metal concentrations.

This is a multidisciplinary project that will apply synthetic organic chemistry, polymer chemistry, metal coordination chemistry and miniaturised device engineering to construct a sensor device employing spectroscopic analysis. Collaboration and interaction with aquatic ecophysiologists and ecotoxicologists, as well as biosensor researchers and environmental/water organisations and the new Centre for Resilience in Environment, Water and Waste (CREWW; https://www.exeter.ac.uk/research/creww/) will facilitate application of this technology in environmental monitoring of metal pollution in freshwater environments. However, the foundation of this project is the design, synthesis and evaluation of novel sensor molecules, hence the successful applicant will require expertise in, and enthusiasm for, synthetic organic chemistry.

Project Aims and Methods:

• Design, synthesise and evaluate solution-based, light-reversible colourimetric sensors for environmentally significant metal pollutants.

• Develop methodology for immobilisation of sensor molecules onto a transparent support (e.g., polymer, glass, graphene).

• Fabricate a sensor device incorporating a transparent, metal-responsive surface and a miniaturised UV-vis spectrophotometer.

• Evaluate sensor performance (sensitivity, selectivity, robustness) in model and real freshwater environments

Project partners:

To be confirmed.


Training: This is a highly interdisciplinary project, hence training will encompass: (i) synthetic organic chemistry, including analytical techniques such as NMR, MS and IR, and polymer synthesis and characterisation; (ii) sensor design, evaluation (using UV-vis spectroscopy) and application; (iii) device fabrication; (iv) sensor application and testing in freshwater environments.

Prospective applicants: For information about the application process please contact the Admissions team via PGRApplicants@exeter.ac.uk.  Each project advertisement has an ‘Apply Now’ button linking to an application portal. Please note that applications received via other routes including a standard programme application route will not be considered for the studentship funding.

Funding Eligibility

NERC RED ALERT CDT studentships are open to UK and Irish nationals who, if successful in their applications, will receive a full studentship including payment of university tuition fees at the home fees rate.

A limited number of full studentships are also available to international students which are defined as EU (excluding Irish nationals), EEA, Swiss and all other non-UK nationals. 

Those not meeting the nationality and residency requirements to be treated as a ‘home’ student may apply for a limited number of full studentships for international students. Although international students are usually charged a higher tuition fee rate than ‘home’ students, those international students offered a NERC RED ALERT CDT full studentship starting in 2024 will only be charged the ‘home’ tuition fee rate (which will be covered by the studentship).

International applicants need to be aware that you will have to cover the cost of your student visa, healthcare surcharge and other costs of moving to the UK to do a PhD. More information on this is available from the universities you are applying to (contact details are provided in the project description that you are interested in.

The conditions for eligibility of home fees status are complex and you will need to seek advice if you have moved to or from the UK (or Republic of Ireland) within the past 3 years or have applied for settled status under the EU Settlement Scheme.

Equality, Diversity and Inclusion

The University of Exeter is committed to promoting and supporting equality, diversity, and inclusion within our working environments and is at the heart of all our activities.  With over 27,000 students and 6,400 staff from 180 different countries we offer a diverse and engaging environment where our diversity is celebrated and valued as a major strength.
