A proteomic map of host cell rewiring by pathogens
Applications are now CLOSED
We aim to develop advanced methods in mass spectrometry-based proteomics and apply them to the question of how host cellular defences are manipulated by bacterial pathogens.
Bacterial pathogens residing within host cells must subvert cellular defences in order to avoid destruction and progress infection. The mechanisms by which bacteria can 'rewire' host cell functions are poorly understood. The delineation of mechanistic details of how host defence systems are manipulated by pathogens is a key goal in contemporary infection biology research and success in this area may lead to the identification of pharmacological intervention targets in the host cell1. This host-directed strategy is attractive from the perspective of antimicrobial resistance (AMR) as it sidesteps the possibility of pathogens evolving resistance by targeting host components of bacterial rewiring.
The principal targets for pathogenic host cell manipulation are the primary functional units of the cell, namely proteins. The functional state of proteins depends on their cellular abundance, post translation modification (PTM) status, and assembly into protein complexes. To assess the state of the proteome we require quantitative measurement technologies. We have recently jointly developed diaPASEF2,3, a mass spectrometry method for sensitive protein quantification from minute quantities of protein (10-200ng) that can be applied to at high throughput (up to 50 samples per day). In this project, we will extend/optimize diaPASEF to assess the state of the proteome during the course of cellular infection with bacterial pathogens. Specifically, our aims are:
(1)Extend the diaPASEF method by:
(i)Optimize the diaPASEF parameter space to maximize ion utilization and selectivity enabling deep proteome coverage
(ii)Adapt diaPASEF for samples enriched for PTMs with relevance in host cell infection biology (phosphorylation, ubiquitination, ISGylation, sumoylation, neddylation)
(iii)Extend diaPASEF for use with our previously developed methods for targeted and global assessment of protein complex assembly state4,5
(2)Apply the methods developed to measure protein abundance, PTM state, and protein complex assembly state, in a host-centric approach to delineating bacterial rewiring in 2 clinically relevant pathogens:
(i)Klebsiella pneumonia is a global concern due to the increasing isolation of multidrug resistant strains. Klebsiella targets PTMs (SUMOylation, Neddylation and ISGlyation) to promote infection, however there is a lack of understanding of which are the critical PTMs modified proteins counteracting the infection. (collaboration with Bengoechea lab)
(ii)Legionella pneumophila, is an emerging respiratory pathogen and the cause of Legionnaires’ disease. L. pneumophila injects more than 300 effector proteins into macrophages and epithelial cells. These actively change the host proteome and signalling, through modulation of translation, cellular stress responses and the ubiquitin system, ultimately establishing an intracellular niche for replication. The function of the majority of effectors and a global view of the changes occurring remain elusive. (collaboration with Schroeder lab).
These pathogens utilize diverse virulence mechanisms and, as such, will demonstrate the broad applicability of our method. The results will provide a broad, dynamic, and integrated map of the host systems targeted by each pathogen. We will assess the functional consequences of removing selected key host cell proteins (by knockdown/out, chemical inhibition) using standard infection assays. Overall, the outcome will be a broadly applicable approach to determine mechanisms of host-cell rewiring demonstrated in 2 clinically relevant bacterial pathogens.
The project will be supervised by Dr Ben Collins (Queen’s University School of Biological Sciences/Institute for Global Food Security), Professor Jose Bengoechea and Dr Gunnar Neels Schroeder (Queen’s University School of Medicine, Dentistry and Biomedical Sciences), and Dr Stephanie Kaspar Schoenfeld (Bruker Daltonics).

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.
There are three broad themes to research at the School:
- Agri-Food Systems and Human Nutrition
- Understanding Health and Disease
- Sustaining Ecosystems and Biodiversity
Agri-Food Systems and Human Nutrition:
This theme focuses on how Agri-Food systems can be better positioned to provide safe and healthy diets and high quality of animal products and support human and animal health in a way that is environmentally sustainable and resilient to climate change.
Underpinning these goals, the disciplinary expertise of the theme integrates basic and applied research from animal health and welfare, nutrition, performance and environmental impact (e.g. greenhouse gas emissions from livestock) to chemical contaminant detection, food microbiology, fraud detection and food systems traceability and transparency.
Supported by underpinning technological expertise in cutting edge molecular, genomic, transcriptomic/proteomic and metabolomic methods, the goal of the theme is to transform Agri-Food systems so that they benefit both human nutrition and health while simultaneously reducing the greenhouse gases emissions from livestock production systems, protecting ecological resources, supporting livelihoods and affordable foods, and upholding social, cultural, and ethical values.
Understanding Health and Disease:
The Understanding Health and Disease research theme covers humans, plants, and animals with research strengths in prevention, diagnostics, surveillance, epidemiology, and treatments. We study how health can be improved through food and nutrition and how diseases can be tackled by understanding their fundamental molecular mechanisms, including those underpinning the biology of pathogens and parasites. Our researchers work in human cancer and genetic diseases, in infections caused by bacteria, fungi, viruses, and parasites, and in how global health and disease will be affected by global warming and climate change.
We recognize that the only way to tackle the problems we face as a society is to take an interdisciplinary approach to our research. This means we have expertise in broad areas including molecular biology, biochemistry, bioinformatics, genomics, transcriptomics, modelling, bioanalytical chemistry, proteomics, metabolomics, microbiology, parasitology, and plant biology. We work internationally with researchers and partners in universities, charities, non-governmental organisations, industry, and government agencies to tackle local and global challenges.
Sustaining Ecosystems and Biodiversity:
This theme covers research in 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, environmental microbiology, microbial ecology, food web analysis, microcosm and mesocosm experiments, and mathematical/computational methods. Within this theme we also 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 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.

People teaching you
Dr Gareth Arnott
Postgraduate Research Director
School of Biological Sciences
For a PhD you will have a principal and second supervisor who advise your independent studies and will be supported by a wider team from the academic staff - who they are, of course, depends on your project. For further details on any aspect of postgraduate research degrees within the School of Biological Sciences, contact: firstname.lastname@example.org. Research degrees are overseen by the School of Biological Sciences Director of Postgraduate Research, who currently is Dr Gareth Arnott.
Learning OutcomesA postgraduate research degree involves the undertaking of independent research under the guidance of a professional academic supervisory team, typically using the laboratory facilities on offer in one or more of the teams' labs. The student will be expected to develop their own ideas and learn the methods needed to test them empirically and theoretically. This usually involves learning and practising both laboratory (and or field) skills as well as developing a strong theoretical background in the relevant subject.
As well as practical work, all the activities of independent academic scholarship, such as literature searching and critical appraisal, written and verbal communications and academic networking will be developed during a research degree. Independence and innovation will be strongly encouraged, but the student will be supported by regular supervisory guidance and a wide range of courses will also be on offer, both in subject specific skills and generic skills, especially supported by the Graduate School (https://www.qub.ac.uk/graduate-school/).
Students are encouraged to interact with one another and with members of academic staff and postdoctoral scientists to build confidence and informal learning, through a range of ‘research culture’ activities, including peer groups where students get together to discuss topical research papers, or methods, or just chat about their interests.
Course structureResearch degrees vary in length, but typically for a PhD they are three or four years long (full-time) and double that for part-time studies. They follow an annual cycle of progress with formal panel-based appraisals of the progress, the outcome of which is typically practical and academic advice about how to overcome problems encountered and how to move to the next stage. During each year, students are expected to supplement their studies with some tailored courses, ranging from highly specific (e.g. learning to use a piece of apparatus or technique) to generic (e.g. developing oral presentation or leadership skills). Every stage is supported by the supervisory team, augmented by an independent panel of progress monitors as well as the full support of the Graduate School.
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.
Supervisors will offer feedback on draft work at regular intervals throughout the period of registration on the degree.
Full-time research students will have access to a desk in a shared office space.
The minimum academic requirement for admission to a research degree programme is normally an Upper Second Class Honours degree from a UK or ROI HE provider, or an equivalent qualification acceptable to the University. Further information can be obtained by contacting the School.

Biological Sciences costs
Students may incur additional costs for small items of clothing and/or equipment necessary for lab or field work
Additional course costs
Depending on the programme of study, there may also be other extra costs which are not covered by tuition fees, which students will need to consider when planning their studies . Students can borrow books and access online learning resources from any Queen's library. If students wish to purchase recommended texts, rather than borrow them from the University Library, prices per text can range from £30 to £100. Students should also budget between £30 to £100 per year for photocopying, memory sticks and printing charges. Students may wish to consider purchasing an electronic device; costs will vary depending on the specification of the model chosen. There are also additional charges for graduation ceremonies, and library fines. In undertaking a research project students may incur costs associated with transport and/or materials, and there will also be additional costs for printing and binding the thesis. There may also be individually tailored research project expenses and students should consult directly with the School for further information.
Some research programmes incur an additional annual charge on top of the tuition fees, often referred to as a bench fee. Bench fees are charged when a programme (or a specific project) incurs extra costs such as those involved with specialist laboratory or field work. If you are required to pay bench fees they will be detailed on your offer letter. If you have any questions about Bench Fees these should be raised with your School at the application stage. Please note that, if you are being funded you will need to ensure your sponsor is aware of and has agreed to fund these additional costs before accepting your place.
