Overview

Rapid evaporative ionisation mass spectrometry (REIMS) is an ambient ionisation technique that allows for the analysis of a sample in <10 seconds without substantial sample preparation. This presents itself as an ideal technology to bring the power of mass spectrometry analysis to the dairy industry; holding potential for rapid, low-cost analysis of milk samples for a breadth of applications. This studentship will be a partnership between the industry body Agrisearch and Queen’s University Belfast to develop REIMS in three key areas of unmet need in the dairy industry. The focus will be developing REIMS as a platform for the identification of the pathogen for bovine mastitis to allow for faster and more targeted treatment of infection and reducing the requirement for the use of broad-spectrum antibiotics. To explore the breadth of potential REIMS applications, two sub-projects will be pursued for examining milk quality and potential biomarkers for lameness in a longitudinal study of a dairy herd. This project will be well suited to students interested in the application of cutting-edge mass spectrometry techniques to solve important issues in the dairy industry and to gain experience in multi-disciplinary research. A budget for training in necessary skills is available as part of the project.

This research project will develop REIMS as a technological platform for the dairy industry. The student will work with the industrial partner (Agrisearch) to collect samples of milk from various dairy herds and build a library for experimental work. The project will combine laboratory work in microbiology and mass spectrometry within the new (opened 2019), purpose-built School of Biological Sciences building.

The four objectives of the proposed research project are:

•Method development of REIMS for diary milk analysis (10% of time): will form the first stage of the project and develop and robust and validated methodology for the analysis of milk samples using REIMS utilising a laser for sample heating and mobilisation. This will determine the optimal volume of milk for analysis, laser power and pulsatile parameters, and mass spectrometry operating conditions. This will further allow the student to develop skills and experience in data analysis workflows specific for REIMS.
•Bovine mastitis diagnosis and treatment management (50% of time): will constitute the main portion of the research programme. Bovine milk samples will be collected from dairy farms which are part of the Agrisearch network and through AFBI from cows with suspected and confirmed mastitis and healthy controls. The effect of novel methods for the control of mastitis, such as antimicrobial peptides, will be modelled and the effect on milk composition measured.
•Development of REIMS for milk quality analysis (20% of time): will explore the potential of REIMS to act as a rapid screening tool for the fatty acid and complex lipid composition of milk samples as a metric of milk quality in comparison to traditional gas chromatography mass spectrometry analysis. Potential applications to the detection of contaminated and/or adulterated milk will be explored.
•Discovery of markers for lameness detection (20% of time): will be conducted as a longitudinal study on a dairy herd with regular samples collected and analysed using REIMS. This cohort will be used to identify potential biomarkers that are indicative of potential lameness prior to observable clinical symptoms.

Academic supervisors will be Dr Simon Cameron and Professor Sharon Huws of Queen’s University Belfast. The industrial supervisor will be Mr Jason Rankin (AgriSearch).

Specific skills required by applicants:

Experience of working in a microbiology laboratory and basic bacteriology skills.
Willingness to learn mass spectrometry techniques, including REIMS, and associated methods for data analysis.
Knowledge of dairy industry within Northern Ireland.
Willingness to develop dissemination material and workshops for dairy farmers and to present research findings at appropriate conferences.
Desirable: access to car/transport that would enable farm visits and sample collection.

Biological Sciences overview

The School of Biological Sciences provides PhD and MPhil (research degree) programmes in subjects ranging from basic biochemistry, molecular genetics and cancer research, to agricultural science, marine ecology and the economic evaluation of ecosystem services and food retailing. If you have a topic or research question in mind, please use the Find a Supervisor link (see Apply tab) to identify the most appropriate member of staff to support your idea. If not, don't worry, we regularly advertise funded projects and there is no harm in browsing our academic staff profiles for inspiration and then contacting whoever seems best: we are very open to applications from suitably qualified people interested in scientific research. In every case, a PhD or MPhil course provides the means of being part of a cutting edge scientific research team and contributing to genuine new discoveries or the development of new methods for practical use. If you cannot study full time, we offer pro-rata part time research degree programmes as well.

To help orientation, the School is organised into three research theme clusters:

- Ecosystem Biology and Sustainability
- Microbes and Pathogen Biology
- Food Safety and Nutrition

Ecosystem Biology and Sustainability:

In this cluster, you could research biodiversity and ecosystem services for environments ranging from tropical forests to deep oceans, using field techniques and skills such as wildlife tracking, taxonomy, geostatistics, molecular and genetic ecology, foodweb-analysis, microcosm and mesocosm experiments and mathematical/computational methods. Alternatively, you could study the behaviour and temperament of wild, agricultural or domestic animals and their implications for welfare and ability to respond to environmental change. Potential research projects include phylogenetic analysis of rare and newly discovered species, examination of ecological interactions in tropical systems, agricultural soils, or marine communities, using state-of-the-art genetic analysis, surveys using drones or satellite tagging, or experiments in tanks and field plots, including careful and ethical examinations of animal behaviour. Projects range from theoretical analysis of stability in ecosystems, through discovery of new species and mechanisms of interaction, or responses to climate change, to the assessment of EU agri-environment schemes, development of new methods for commercial fisheries management and economic evaluations of conservation measures. Projects very often have an international dimension and include collaboration with other researchers worldwide.

Microbes and Pathogen Biology:

This cluster covers a diverse array of research interests united by an emphasis on molecular approaches applied to both fundamental and applied questions over the range from molecular to ecological systems. These interests include biochemistry, food safety, microbiology and parasite control with applications in human and animal health, nutrition, plant and soil sciences, and agricultural development. We have a long-standing reputation in parasite biology and in applied microbiology (for example in clearing land of contamination) as well as strong contributions to fundamental methods in understanding cancer, developing veterinary vaccines and molecular detectors for toxins and diseases. The common thread is our strong molecular approach using and developing cutting edge genomic, transcriptomic/proteomic methods. Research students in this cluster enjoy a range of strong international links across Europe, Asia, North and South America.

Food Safety and Nutrition:

Research opportunities offered by this cluster span the entire food chain "from farm to fork" with a strong emphasis on food safety and nutrition, public health and food security. In this cluster you would conduct research under the supervision of leading scientists based in the Institute for Global Food Security and benefit from integration with business experts, helping you gain leadership positions nationally and internationally.

Assessment

Assessment processes for the Research Degree differ from taught degrees. Students will be expected to present drafts of their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually.

This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year.

The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.

Feedback

Supervisors will offer feedback on draft work at regular intervals throughout the period of registration on the degree.

Facilities
Full-time research students will have access to a shared office space and access to a desk with personal computer and internet access.
