Project Title: Protecting the Food Chain by Rapid On-Site Nanopore DNA Sequencing
The adulteration of food products with meat derived from unexpected species greatly affects consumer confidence and may pose health risks. High-profile cases such as the 2013 horsemeat scandal has increased pressure to improve the reliability and speed of species identification. Unfortunately current methods for checking raw meats require out-sourced laboratory testing using expensive equipment, which can take up to a week. Similar delays occur when testing for pathogenic microbes, by which time food from potentially contaminated production lines may have already reached retailers and consumers.
We seek a highly-motivated student with an interest in genetics, genomics or forensic genetics, whose research project will develop rapid, on-site species identification methods using the Oxford Nanopore Technologies (ONT) MinION portable third-generation sequencing device. The focus will be on mitochondrial barcode genes that show characteristic sequence differences between species; a similar approach can identify bacteria from their 16S rRNA sequences. ONT sample and sequencing preparation devices currently in development, including the VolTRAX microfluidics platform and Zumbador (hand-held disposable DNA library preparation system) will be trialled for utility upon release.
Our industrial partner is Cranswick Convenience Foods, the UK’s largest supplier of cooked meats to UK supermarkets. The student will benefit from the opportunity to observe at first-hand how a food processing company works, gain an appreciation of the technology involved in large-scale food processing, and the processes needed to ensure food-chain integrity. They will be trained in existing food-testing methodologies, and visit third-party testing companies used by Cranswick to understand other approaches to species identification. During the course of the project the student is expected to spend at least 3 months with the industrial partner.
The technological solutions developed through this research project are also applicable in other settings, such as the detection of illegal by-catch in fisheries, and the sale of bushmeat - wild animals caught in developing countries that are butchered and sold in markets. There will be opportunities to explore these avenues during the project.
Supervision, training and academic environment
You will be part of the Midlands Integrative Biosciences Training Partnership (MIBTP), a BBSRC-funded Doctoral Training Partnership between the Universities of Warwick, Birmingham and Leicester. As an iCASE student, you must fulfil the MIBTP entry requirements and will join the MIBTP cohort for the taught modules and masterclasses during the first term. You can then start your PhD project in Jan 2018 but must complete a 3-month miniproject (at a non-home institution) before the end of their first year. You will remain as an integral part of the MIBTP cohort and take part in the core networking activities and transferable skills training.
You will be supervised by an experienced supervisory team and form part of a dynamic and productive research group studying human and animal genetic diversity, with projects in population genetics, forensics, recombination and mutation biology, and human disease genetics.
Closing date for applications: 31st July 2017
