This project is one of a number that are in competition for funding from the NERC GW4+ Doctoral Training Partnership (GW4+ DTP). The GW4+ DTP consists of the GW4 Alliance of research-intensive universities: the University of Bath, University of Bristol, Cardiff University and the University of Exeter plus five unique and prestigious Research Organisation partners: British Antarctic Survey, British Geological Survey, Centre for Ecology & Hydrology, the Natural History Museum and Plymouth Marine Laboratory. The partnership aims to provide a broad training in the Earth, Environmental and Life sciences, designed to train tomorrow’s leaders in scientific research, business, technology and policy-making. For further details about the programme please see http://nercgw4plus.ac.uk/
For eligible successful applicants, the studentships comprises:
- An stipend for 3.5 years (currently £15,009 p.a. for 2019/20) in line with UK Research and Innovation rates
- Payment of university tuition fees;
- A research budget of £11,000 for an international conference, lab, field and research expenses;
- A training budget of £3,250 for specialist training courses and expenses.
- Travel and accomodation is covered for all compulsory DTP cohort events.
- No course fees for courses run by the DTP
We are currently advertising projects for a total of 10 studentships at the University of Exeter
Students who are resident in EU countries are eligible for the full award on the same basis as UK residents. Applicants resident outside of the EU (classed as International for tuition fee purposes) are not eligible for DTP funding. Residency rules are complex and if you have not been resident in the UK or EU for the 3 years prior to the start of the studentship, please apply and we will check eligibility upon shortlisting.
Enumeration and classification of plankton from environmental samples is key to determining ecosystem function and their role in the marine food web. Traditional enumeration methods using microscopy are often slow and laborious. The availability of automated imaging microscopy platforms such as FlowCam has revolutionized the way plankton can be detected within their natural environment such that there is now a requirement for automated classification techniques to deal with the enormous volume of digital data produced. The aim of this project is to use state-of-the-art machine learning and pattern recognition approaches, such as deep learning, to analyse plankton shapes and develop automated algorithms for plankton identification and quantification. The project is a collaboration between the University of Exeter’s Institute for Data Science and AI and the Plymouth Marine Laboratory (PML), a charity undertaking pioneering marine research to further our understanding of the dynamic and complex marine environment and inform knowledge-based solutions to the challenges our oceans face.
Project Aims and Methods
The aims of this project will be as follows:
- Explore the applicability and scalability of deep learning approaches for plankton identification from Flowcam imaging. The quantity of plankton species as well as the variety of appearances within each species makes this problem an especially challenging one for machine learning.
- Develop an approach for large-scale plankton identification and quantification from microscopy images containing multiple targets.
- Develop a comprehensive dataset and benchmark for plankton classification for the research community.
The project will make use of state-of-the-art machine learning approaches, including Deep Neural Networks and Generative Adversarial Models to analyse the microscopy images. Note that this project offers a large flexibility in its aims and methods used and that both partners would expect the doctoral student to take the lead and propose further development as the project progresses and new developments arise in the literature.

The ideal candidate should have a first-class undergraduate degree, preferably in Computer Science or Mathematics, and optionally an MSc in Data Science, AI or a related subject. The candidate should have a broad interest in life science and into learning more about marine biology.
CASE or Collaborative Partner
PML has approximately 45 PhD or MRes Students and is a member of the GW4+ Doctoral Training Partnership (DTP). PML provides access to exceptional capabilities in the collection and processing of marine samples, and quantitative analysis techniques. The student will be fully integrated into the relevant research groups at PML, where they will have the opportunity to learn how the image data is collected and used. As part of their training, they will have the opportunity to take part in at least one research cruise aboard the Plymouth Quest, which is owned and operated by PML.
- The student will benefit from all training resources available at the university of Exeter and the Plymouth Marine Laboratory.
- The student will be offered to enrol in any course that could further her or his understanding of the required methodologies (eg, Machine Learning or Data Science).
- Attendance to the British Machine Vision Summer School will also be encouraged.

Applicants should have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK. Applicants with a Lower Second Class degree will be considered if they also have Master’s degree. Applicants with a minimum of Upper Second Class degree and significant relevant non-academic experience are encouraged to apply.
All applicants would need to meet our English language requirements by the start of the project http://www.exeter.ac.uk/postgraduate/apply/english/.
How to apply
In the application process you will be asked to upload several documents. Please note our preferred format is PDF, each file named with your surname and the name of the document, eg. “Smith – CV.pdf”, “Smith – Cover Letter.pdf”, “Smith – Transcript.pdf”.
