Epigenetic basis of nutrition-mediated development in the honeybee

Research environment

The School of Biological and Behavioural Sciences at Queen Mary is one of the UK’s elite research centres, according to the 2021 Research Excellence Framework (REF). We offer a multi-disciplinary research environment and have approximately 180 PhD students working on projects in the biological and psychological sciences. Our students have access to a variety of research facilities supported by experienced staff, as well as a range of student support services.

The Hurd lab employs functional epigenomics as a successful research theme; integrating molecular biology, biochemistry, proteomics and genomic approaches in honey bees in an effort to understand the epigenetic basis for gene-environment interactions during organismal development. Our research is focussed on the honey bee as an emerging model organism for epigenetics and we study how nutrition dictates the capacity of the honey bee genome to produce three phenotypically distinct organisms. Currently consisting of 2 postdoctoral researchers and 1 PhD student, the Hurd Lab is funded by UK national funding bodies (Biotechnology and Biological Sciences Research Council) and the European Comission through EASI-Genomics. 

Training and development

Our PhD students become part of Queen Mary’s Doctoral College which provides training and development opportunities, advice on funding, and financial support for research. Our students also have access to a Researcher Development Programme designed to help recognise and develop key skills and attributes needed to effectively manage research, and to prepare and plan for the next stages of their career.

In addition, the Hurd lab is a founding member and core group of the QMUL Epigenetics Hub (http://qmulepigenetics.com/home). This provides considerable added value and experience for the training of the student. Joint lab meetings are held and attended by all groups, providing a very knowledgeable, stimulating, varied and dynamic environment. The student will be expected to give a seminar on their work every four months, which will not only develop their presentation skills but will provide an advisory group of fourteen other group leaders.               

Project description

The honey bee is an important emerging model organism for understanding epigenetic mechanisms. The honey bee genome encodes three phenotypically distinct but genetically indistinguishable organisms (queens, workers and drones) that are determined during early post-embryonic development by differential nutrition. The molecular mechanisms responsible for this differential development are unknown but through previous and current funding, we were the first to demonstrate that queen, worker and drone honey bees have phenotype-specific chromatin epigenetic states that establish and orchestrate the distinct patterns of gene expression that determine developmental trajectory.
                                                                                                                                                                                                               Building on this work, the PhD project will examine the role of specific nutritional components as epigenetic modulators of phenotypic plasticity during development using our well-established in vitro honey bee rearing techniques. The student will be trained in state-of-the-art molecular techniques for epigenomics (ATAC-seq, ChIP-seq, CUT&RUN, CUT&TAG, RNA-seq), proteomics (mass spectrometry), metabolomics (gas chromatography-mass spectrometry), biochemistry (chromatin biology, recombinant protein techniques) and apiculture (general beekeeping, queen rearing, in vitro bee rearing). You will not only obtain hands on experimental approaches but also develop proficiency in computational and statistical analyses of large genomic datasets.            

The aim of this multidisciplinary PhD project is to exploit the unique opportunities of the honey bee system to understand how an environmental cue (nutrition) shapes phenotype through epigenetic mechanisms in an economically and ecologically important organism.

Funding

This studentship is open to students applying for CONACyT funding. CONACyT will provide a contribution towards your tuition fees each year and Queen Mary will waive the remaining fee. CONACyT will pay a stipend towards living costs to its scholars. Further information can be found here: https://conacyt.mx/convocatorias/convocatorias-becas-al-extranjero/

Eligibility and applying

Please refer to the CONACyT website here: https://conacyt.mx/convocatorias/convocatorias-becas-al-extranjero/ for full details on eligibility and conditions on the scholarship. 

Applications are invited from outstanding candidates with or expecting to receive a first or upper-second class honours degree in an area relevant to the project such as molecular biology, biochemistry, biomedical science, genetics, developmental and cell biology. Some previous computational experience would be an advanatge. A masters degree is desirable, but not essential.

Applicants from outside of the UK are required to provide evidence of their English language ability. Please see our English language requirements page for details: https://www.qmul.ac.uk/international-students/englishlanguagerequirements/postgraduateresearch/ 

Informal enquiries about the project can be sent to Paul Hurd at p.j.hurd@qmul.ac.uk 

Applicants will need to complete an online application form to be considered, including a CV, personal statement and qualifications. Shortlisted applicants will be invited for a formal interview by the project supervisor. Those who are successful in their application for our PhD programme will be issued with an offer letter which is conditional on securing a CONACyT scholarship (as well as any academic conditions still required to meet our entry requirements).

Once applicants have obtained their offer letter from Queen Mary they should then apply to CONACyT for the scholarship as per their requirements and deadlines, with the support of the project supervisor.

Only applicants who are successful in their application to CONACyT can be issued an unconditional offer and enrol on our PhD programme.
