About the Project

Supervisors: Prof Graham Pierce, Dr Norval Strachan, Dr Campbell Pert

Background: PhDs are offered in University of Aberdeen, Oceanlab (www.oceanlab.abdn.ac.uk) funded by MASTS (www.masts.ac.uk/) in the field of “Platforms & Sensors” applying new technology to marine science jointly between the Colleges of Physical Sciences and Life Sciences & Medicine in the University of Aberdeen and a MASTS partner.

Parasites located in the flesh of fish are an important concern for food safety and quality. An ultra-violet imaging device for the detection of parasites in fish flesh has been developed (Levesen and Lunestad, 2010). The EU-funded PARASITO project will optimise the illumination and fluorescent excitation wavelengths from the parasites and the role of this PhD will be to:

(1) Develop algorithms to optimise the detection of parasites in fish fillets,
(2) Determine if the parasites are alive or dead and also determination of their species,
(3) Evaluate the efficacy of these algorithms after the fish have been minimally processed (e.g. frozen, heated, marinated, salted etc.)
The project will benefit from a bio-bank of parasites and contaminated fish flesh that will be available through the project. The student will develop:
(1) Imaging and pattern recognition skills,
(2) Technical instrumentation competence
(3) Knowledge of the biology of fish-borne parasites,
(4) Understanding of European fisheries.
