EastBio PhD: Chronic-Stage Cyst Formation in Toxoplasma and Neospora

EastBio PhD: Chronic-Stage Cyst Formation in Toxoplasma and Neospora

Research question and applicant decision

This four-year Edinburgh PhD (project 200206) studies chronic-stage parasite biology through protein and imaging evidence, comparing Toxoplasma and Neospora; the named supervisor is MRC Research Fellow Joanna C. Young. The saved paper record includes two 2024 primary studies coauthored by Young. Cellpose3 (2025) is an independent, adjacent imaging study: Young is not an author, and it does not validate this project. The 2020 paper is historical context. International applicants compete for awards; the 2027 stipend and personal costs require confirmation. Current application status is not established by the saved materials. Applicants should clarify the student's independent, feasible contribution and how it differs from existing lab work. Current official recruitment route; International award boundary

Research Question and Doctoral Work

The advert links Toxoplasma and Neospora to chronic-stage biology and livestock reproductive disease, including effects on sheep and cattle respectively. It also gives an approximate one-third global human Toxoplasma background estimate. This is contextual epidemiology, not individual infection probability, testing or treatment advice. Chronic stages are scientifically difficult, and the project does not claim an existing drug that clears them.

The doctoral question concerns poorly understood chronic-stage protein biology. Public recruitment-level duties include protein localisation, interaction and functional-evidence interpretation, microscopy and high-throughput image analysis, and comparison between cyst-forming apicomplexan systems. Training also spans parasitology and molecular biology. The important intellectual distinction is that observing a protein’s presence, location or association does not establish its complete biological function. Comparative conservation requires evidence rather than assuming one species predicts another.

It is not a promise of a computation-only route. The advert specifies no mandatory imaging software, prior instrument certificate, personal compute allocation or fixed final product. The student’s division between imaging, quantitative analysis and other work, model responsibilities and access conditions must be agreed institutionally.

The field’s value is a clearer connection between molecular observations and chronic-stage cellular biology; the difficulty is interpreting observations across context, stage and species. Better spatial observation is not itself causality, and an explanatory finding is not clinical efficacy. Applicants should ask what independent thesis contribution is feasible within four funded years, how uncertainties are assessed and which training/analysis support already exists. The three recent original studies and one inherited 2020 historical reference cited below outline research trajectory and evidence limits; they are not a ready-made thesis result.

School, Programme and Field Context

The degree-awarding institution is University of Edinburgh, United Kingdom, and the academic home is School of Biological Sciences. The saved delegated directory places this project in Institute of Immunology and Infection Research. University institutes and centres can overlap with supervisors’ affiliations; they do not create a joint or double degree. Confirm the physical host and day-to-day group. Official current recruitment route

The specified registration is Biological Sciences (with Internship) PhD, 48 months full-time, starting 1 October 2027, at the University of Edinburgh. The first year is probationary; a thesis committee supports progress, and students must pass an annual review to progress. First-year reports are due at 10 weeks and 10 months, with an oral presentation at the latter review. The programme describes a year-two poster, a year-three research presentation, and a final thesis of up to 100,000 words defended in a viva. Cohort training spans methods, research, professional and thematic skills. The advert includes a three-month placement; ordinary PIPS is typically up to three months, or up to six with approval. The project is not marked CASE and names no company; host, timing and expenses remain to be agreed. Exact programme and registration; Training framework

The School’s REF 2021 Biological Sciences account reports 94% world-leading/internationally excellent research and 100% world-leading environment, with a UK-top-five subject claim. This is a dated national subject assessment, not a 2027 global ranking or a score for the individual lab. Research training is not a clinical qualification. Subject evidence and assessment year

Supervisors, Recent Primary Research and Resources

The official profile identifies Joanna C. Young as MRC Research Fellow, ORCID 0000-0001-6417-928X. She is the parasitology researcher, not the same-name scientific-editing/researcher-development trainer. The lab describes an MRC Career Development Fellow who established her Edinburgh group in September 2021, following Imperial doctoral and London parasitology experience. The team page lists postdoctoral, technical and doctoral roles, including EastBio students. This is evidence of a functioning training group, not a student-to-supervisor ratio or guaranteed daily availability. Correct institutional identity; Actual team roles; Institute home

The profile lists an MRC research award ending 5 November 2027 and a collaborative BBSRC project ending 30 November 2027. These dates are close to this PhD’s October 2027 start. Those dates alone neither establish closure nor guarantee four-year supervisory appointment or research-budget continuity. Ask how continuity is secured under the actual 2027 studentship/appointment arrangements. This is an advertised studentship, not a salaried employment contract; no employment salary, probation or pension is promised.

The saved review of the two Young-coauthored 2024 studies reached institutional abstracts and bibliographic records only. The Cellpose 3 review covered a selected publisher abstract, discussion sections, author information and metadata. No complete methods or supplement assessment is claimed. The saved record therefore supports two recent Young-coauthored originals; Cellpose 3 is an independent adjacent-imaging study, and the 2020 paper is historical.

Torelli and colleagues: limits of inference

Francesca Torelli; Diogo M da Fonseca; Simon W Butterworth; Joanna C Young; Moritz Treeck. Paracrine rescue of MYR1-deficient Toxoplasma gondii mutants reveals limitations of pooled in vivo CRISPR screens. eLife 13: RP102592. publication 2024-12-10. DOI: 10.7554/eLife.102592.

Young is fourth of five authors. Dominique Soldati-Favre is identified as editor in the university record and must not be added as a sixth author. The institution labels the work published and peer reviewed; the saved check did not resolve the publisher version because its page presented a client challenge.

The applicant-level lesson is caution when transferring conclusions between research contexts, not an experimental or engineering recommendation. The paper does not validate the proposed chronic-stage, cross-species thesis. 2024 interpretation-limit study

Bondarenko and colleagues: spatial imaging

Kseniia Bondarenko; Floriane Limoge; Kayvon Pedram; Mathieu Gissot; Joanna C. Young. Enzymatically enhanced ultrastructure expansion microscopy unlocks expansion of in vitro Toxoplasma gondii cysts. mSphere 9(9): e00322-24. Online 2024-08-27; publication 2024-09-25. DOI: 10.1128/msphere.00322-24.

Young is fifth of five authors and marked corresponding author in the institutional record.

The work supports the group’s spatial-imaging expertise and illustrates the value of resolving localisation, while sample-dependent performance limits transfer and localisation does not establish complete function or clinical efficacy. No preparation, target or procedural details are reproduced. The saved review of this study reached the institutional abstract and bibliographic information only; methods and supplements were not assessed. 2024 imaging primary study

Independent image-analysis study

Carsen Stringer; Marius Pachitariu. Cellpose3: one-click image restoration for improved cellular segmentation. Nature Methods 22:592–599 (2025), DOI: 10.1038/s41592-025-02595-5, was published online 12 February 2025, with the March issue.

This peer-reviewed original Article is from HHMI Janelia Research Campus; Joanna Young is not an author.

It evaluates image restoration and segmentation on varied microscopy data, including degraded images. Its relevance is learning to judge quantitative image evidence, not a claim that this lab uses or requires Cellpose3. The discussion cautions that learned restoration may introduce apparent features and that better-looking images need not preserve quantitative biological information. It is independent adjacent imaging evidence, not chronic-stage parasite evidence or validation of this exact project. 2025 independent imaging original The review covered a selected publisher abstract, discussion sections, author information and metadata; it did not assess the full methods or supplements.

Historical study

Young et al., mSphere 5(5), 28 October 2020 (early online 9 September), describes protein-associated observations across biological stages and limits of interpreting them causally. It is older than five years, not a third recent primary paper. Its relevance is the group leader’s earlier protein/imaging trajectory; it does not establish exact Neospora results or future thesis feasibility. No particular regulatory factor or functional manipulation is transferred. The 2020 citation is retained as inherited historical context; its actual reading scope is unrecorded. Historical 2020 primary study

School microscopy, protein/omics and analytical services are relevant institutional resources, not personal allocation. Ask which imaging-analysis support and computational capacity are available, the balance between the two species, and who provides backup supervision during placement or appointment transitions. Shared resources

Funding and International Costs

The saved project call advertises a four-year fully funded competition for either an EASTBIO BBSRC Doctoral Landscape Award or an Edinburgh Doctoral College Award. It is open worldwide and describes a monthly stipend at the UKRI standard rate, tuition cover and support for project costs; no separate EDC application is required. This confirms an advertised studentship opportunity, not an award already made to an individual. The 30% international intake limit described in the EASTBIO/UKRI guidance must not automatically be applied to the separate EDC route or treated as an applicant’s probability of success. Confirm the named award, overseas-fee treatment and 2027 stipend in the offer. EASTBIO international rules; School funding routes

The School describes EDC support as tuition plus a four-year stipend and project grant £5,000 in years 1–3 and £1,000 in year 4: £16,000 total research support, not extra living income. UKRI's confirmed 2026/27 minimum is £21,805 stipend and £5,238 Home-fee contribution; the 2027/28 rate is not yet given there. EDC grant scope; Confirmed current UKRI reference

The university estimates 2026/27 living costs £18,504/year or £1,542/month, calculated March 2026: accommodation/utilities £978, food/shopping £248, mobile £12, social/leisure/wellbeing £246, bus (age 22+) £58 monthly. Accommodation/utilities illustrations range £752–£1,249/month; the lower private figure is based on a room-share calculation, not a private whole-flat quote or guaranteed place. These are dated planning references; the 2027 award amount, housing choice and excluded arrival/travel costs must be checked separately. No disposable-income balance is calculated. Current budget methodology

The saved October 2026 Student visa application fee is £558, and student IHS is £776/year with partial-year charging rules. If chargeable permission were 4.5 years, the IHS example would be £3,492, or £4,050 with the application fee; actual CAS/permission duration and future rates determine the bill.

The outside-London visa maintenance figure £1,171/month for up to 9 months (£10,539) is a regulatory evidence threshold, not a full-year Edinburgh budget. Sponsorship/CAS and Chinese differential-evidence arrangements require individual checking. Travel, deposits and cash before the first stipend remain separate. Visa fee; IHS rules; Maintenance evidence

Background, Language and Application

The captured advert does not add a specific prior software package, instrument mastery, parasite-publication record or master’s requirement. Parasitology, molecular/protein biology, microscopy and quantitative image interpretation are useful preparation areas, not a list of invented mandatory accomplishments. The programme normally expects a relevant UK 2:1 or international equivalent, some research experience and good understanding of the proposed field. Relevant industrial experience may partly meet the research-experience expectation; non-standard backgrounds are assessed case by case. EastBio does not generally require a master’s. Chinese degree equivalence is assessed individually. Mentioned methods are not automatically pre-entry requirements. Actual degree requirements

For 2027 entry, the programme specifies IELTS 6.5 overall/6.0 each, without One Skill Retake. TOEFL taken before 21 January 2026 uses 92 overall/23 each; from that date the new scale requires 4.5 overall/4.5 each, without MyBest aggregation. Check validity and alternative qualifications on the programme page. Non-English academic records require originals plus official translations. An application may precede the English test, but final offer conditions still apply. Student-visa holders must register full-time and live within commuting distance; individual ATAS/CAS conditions must be checked. 2027 language criteria; International study conditions IELTS and TOEFL must be no more than two years old on the first day of the programme’s starting month. An English-taught degree is an alternative only under the University’s approved country/institution and age rules.

Only one EastBio project across all hosts may be selected. Contact the named supervisors, prepare the 2027 EastBio form, transcripts, anonymous EDI-survey response ID, and two references using the official form. Referees can be academic/professional but cannot be the project supervisors. Extra documents such as CVs are disregarded in the formal process; an informal supervisor contact is distinct. The programme charges no application fee. Mandatory application materials; Document rules

Submit through Euclid: Biological Sciences with Internship, 1 October 2027, enter title/supervisors/funding source, and upload the EastBio form to the Research Proposal section. The upload label does not itself request an additional experimental proposal. The captured exact instructions give midday Monday 16 November 2026, with references accepted up to two weeks afterwards; the seed does not specify a timezone. Central guidance requests references by 16 November and says incomplete references disadvantage shortlisting. Aim for all documents by the main deadline and obtain written host confirmation before relying on an extension. Euclid can email referees a link, but they still need the official template. Application route and main deadline; Reference timing and exceptions

The project instructions keep applications under consideration until 22 February 2027, request missing information through Euclid, and reserve amendment/withdrawal of scholarships. Check the portal and email. Central dates are 18 January nominations, 22 February interview invitations, week beginning 8 March interviews, week beginning 22 March decisions, with 1 October entry. These are selection stages, not an interview or award promise. Current selection timetable

Career directions

The transferable value is rigorous quantitative interpretation, critical comparison and collaborative biological research. The National Careers Service gives a broad UK biochemist occupation range of £28,000 starter–£53,000 experienced. It is a general labour-market reference, not this project’s placement record or a promised salary. Career evidence and its scope

Next Actions and Questions by Stage

Before applying: choose the single project; confirm degree equivalence, English evidence and the host’s reference deadline. The saved delegated directory lists the exact opportunity; current availability still needs confirmation. The observed university project target failed to connect; its body was not read.

At interview: clarify the independent contribution and balance between comparative protein evidence, imaging and analysis; which species/model responsibilities are actually assigned? Ask how appointment and research-resource continuity are supported after existing 2027 grant end dates, and who supplies daily/backup supervision. Request any further recent Young-team primary references if available; the added independent imaging study does not fill the evidence gap about a third recent supervisor output. Confirm ordinary placement, training and approved work responsibilities without assuming specific material access.

Before accepting: obtain the named award, 2027 stipend and international fee waiver in writing; confirm research/placement expenses, funded period and completion arrangements. Check the supervision/committee agreement, individual CAS/ATAS conditions, housing, arrival cash and excluded visa/IHS charges. Neither shared facilities nor a supervisor’s publication/grant record guarantees personal access, current supervisory capacity or career outcomes.
