PhD: Sleep, Circadian Rhythm and Brain Vascular Health in Ageing

PhD: Sleep, Circadian Rhythm and Brain Vascular Health in Ageing

University of Birmingham is the registering institution; saved programme material lists an October 2027 intake.

Research question and project fit

This opportunity adds sleep and circadian measurement to an already funded exercise/brain-ageing study. Its advantage is access to an established multidisciplinary intervention rather than having to create an entire ageing cohort. Its scientific challenge is explaining variable responses without assuming that better fitness necessarily increases cerebral blood flow or cognition. Professor Katrien Segaert is primary supervisor and Professor Clare Anderson secondary supervisor; Birmingham registration is explicit. It suits quantitative cognitive/sleep-neuroscience research, with feasibility depending on recruitment and the sleep module's measurement timetable. Official project.

The saved call lists October 2027 entry and a 23 November 2026 deadline; present acceptance and the closing clock are unverified. Birmingham explicitly covers all tuition including international fees for successful MIBTP awardees, with a UKRI-rate stipend. International awards remain competitive, with the international share capped at 30% per MIBTP cohort; whether that cohort covers the entire partnership remains unconfirmed. This limit does not indicate this project's award allocation or an individual applicant's chance; the project-specific award count is unconfirmed. Domestic Chinese applicants may use that route, with individual academic/fee-status assessment; no universal Chinese grade threshold was established. Birmingham recruitment and support, China country information.

Research Problem and Doctoral Work

Sleep quality and circadian timing may connect fitness, brain perfusion and cognition in later life, but they are distinct constructs. The project adds them to an existing study with brain scans, fitness tests and cognitive assessment. It asks four questions: how sleep/rhythms relate to fitness, brain blood flow and memory/cognition; whether a year-long structured exercise programme improves sleep and circadian alignment; whether these changes help explain cognitive/brain benefits and individual response differences; and whether sleep/rhythms relate to plasticity blood markers already measured in the parent study.

Advertised measurements are a wrist monitor, brief sleep questionnaire, activity/light data and a sleep-sensitive memory task. Both cross-sectional and longitudinal statistical analyses are explicit. The supplied project description calls the light devices “Light pins”; the saved official outline simply says light data. Exact device, wear duration, phase markers, scoring algorithms and sampling cadence are unconfirmed. EEG/polysomnography or melatonin assessment must not be silently added to the work plan because the department owns a sleep lab.

Analytically, activity-derived rhythm regularity is not the same as a direct measurement of internal circadian phase. Repeated observations can distinguish within-person change from stable differences, but a mediation association alone does not prove sleep causes an exercise benefit. Season/light exposure, baseline health, adherence, missing wear data and measurement timing are relevant possible explanations to discuss, not advertised covariates already confirmed in the protocol. The most useful output would be a well-defined sleep/rhythm phenotype linked to vascular/cognitive response with appropriately bounded uncertainty, not an intervention-effect guarantee.

School, Programme and Field Context

The project belongs to School of Psychology, College of Life and Environmental Sciences, University of Birmingham. The exact application programme is 181D PhD in School of Psychology MIBTP. Birmingham is the registering university; the six-university partnership is not evidence of a joint degree. MIBTP is a four-year studentship with training alongside doctoral research, not a one-year degree because the exercise intervention lasts one year. The published detailed training timetable remains labelled 2025 and its 2027 calendar needs confirmation.

Birmingham is equal 68 globally in QS 2027 overall. Its REF 2021 Psychology/Psychiatry/Neuroscience submission reports 54% 4* and 40% 3* research; these are combined-unit quality proportions, not a Psychology rank or individual-lab success rate. CHBH and the exercise team supply relevant infrastructure. A February 2026 university announcement describes a £1.9m BBSRC exercise/brain-vascular programme and Age UK Birmingham partnership; the grant budget is not this student’s personal allocation. REF table, parent research environment.

Supervisors, Publications and Research Conditions

Segaert’s saved project profile connects cognitive ageing, exercise and neurovascular mechanisms. Her older staff page emphasises language neuroscience and uses an older Associate Professor title; the saved MIBTP page names Professor. Anderson is Professor of Sleep and Circadian Science with healthy-ageing, biomarker and field/laboratory expertise. That combination is more relevant than simply calling the project psychology. Segaert staff research, Anderson profile.

Segaert describes at least fortnightly scheduled meetings and work on a shared rota. The CHBH sleep-lab primary description lists controlled sleep suites, EEG/PSG and biological/cognitive endpoints. That supports a substantial methodological environment, while actual access, training and whether any such lab measurements belong to this wearable-based PhD remain unconfirmed. Sleep-lab environment.

Publication evidence and its limits

The following studies inform vascular measurement, exercise-response interpretation and sleep-task choice. Full bylines and individual contribution records for the first two were not established. The selected-paper and abstract scopes below belong to the earlier report, not new full-paper reading. None directly tests this doctorate's sleep-mediation pathway.

Vascular phenotype and fitness: 2024 cross-sectional study

Feron et al., Aging 16:12473–12497. In 78 healthy adults aged 60–81, multi-delay ASL separated cerebral blood flow (CBF) from arterial transit time (ATT). BMI and age showed associations, while fitness was not a simple higher-CBF signal and measured cognition did not correlate with CBF/ATT. This supports vascular-phenotype definition; the cross-sectional design cannot establish intervention effects. The earlier reading covered publisher methods/results context. Study.

Exercise response: 2024 randomised study

Feron et al., NeuroImage 303:120919. The 26-week RCT included 65 older adults. Fitness improved, but overall between-group CBF/ATT and cognitive changes were not significant; higher fitness responders showed CBF reductions without associated cognitive gains. This motivates response-heterogeneity research rather than a promise of improved perfusion. It is an earlier study, not the future year-long cohort. The earlier reading covered relevant PDF results/discussion. RCT.

Task-dependent sleep-loss effects: 2025 study

Francis-Pester et al., Sleep 48:zsaf144; Anderson is corresponding author. In 17 younger and 17 older healthy adults, sleep-initiation and attentional-control outcomes differed in age sensitivity. Not falling asleep does not establish intact attention; task choice matters. The older group was 50–65, limiting transfer to later-life cohorts. The earlier reading covered the complete institutional structured abstract/metadata; full text was inaccessible, so this is not a full-paper appraisal. Study and reading scope.

The first two papers involve a related research programme and should not be treated as independent large replications. None tests the proposed sleep mediation pathway directly. The parent programme reduces setup risk, but data availability, participant overlap and the sleep module’s timeline still determine feasibility.

Funding, Application and Living Cost

Successful Birmingham MIBTP awards cover home and international tuition, and 2026/27 reference stipend is £21,805 tax-free annually (about £1,817.08 monthly). The 2027/28 rate is not confirmed by the saved primary pages. Travel/conference, consumables and laptop support are programme components; precise personal/training-travel allocation belongs in the offer. The international award cap is competition context, not a probability of admission. UKRI confirmed rate.

Birmingham’s local postgraduate budget page lists 50-week essentials of £9,250 in self-catered halls or £8,700 in private housing, plus £5,500 variable costs. The page is undated and contains legacy initial-cost items, so those are component examples, not current 2027 rent quotes or a complete 52-week doctoral budget. Check housing contract length, utilities, commuting and placement travel. For transparent sensitivity only, monthly spending £1,600 or £1,900 would leave about £217.08 or a £82.92 deficit against the 2026/27 reference stipend; these scenarios are not promised savings. Local budget components.

The saved student IHS reference is £776 per visa year; visa duration may exceed course length. Visa application, travel and relocation funds are separate. Do not finance an application on assumed casual work or a generic programme immigration-cost estimate. IHS, Student visa.

Birmingham allows one project per programme and up to five separately submitted programme applications. This sleep project and ‘From brain to plate’ both use 181D, so an applicant must choose between them for that programme. Multiple projects or the wrong link can cause rejection. Name the exact project and supervisor, answer the research-methods training question, upload CV and English academic records and select BBSRC Research Council Funding. No research proposal is required; a blank upload is permitted. The personal statement is optional with N/A permitted; complete EDI after submission. Saved guidance targets late-January 2027 shortlisting and early-February overseas Zoom interviews.

MIBTP accepts relevant first/high 2:1 backgrounds, with stated lower 2:1 plus Master's/relevant-experience routes; individual overseas equivalence requires admissions assessment. The specific 181D English condition and 2027 Chinese qualification conversion were not independently established. English proof may follow initial application, but the eventual offer conditions must be met. The linked general table is dated 2026 and has programme exceptions; do not import generic Science or clinical-psychology requirements. Linked language guidance.

Applicant Preparation and Career Value

Psychology, neuroscience, sleep science, exercise science or a quantitative background can be relevant when backed by research-methods competence. Prior mastery of all MRI, sleep-lab or biomarker techniques is not an advertised condition. The strongest preparation would show reproducible analysis of repeated measurements, clear distinction between correlated and causal explanations, and willingness to coordinate older-adult data collection. A purely theoretical/software project without participant-facing commitments is a less direct match.

Suggested evidence includes an example of handling missing repeated data, justifying a behavioural measure, and communicating results with null effects. These are analyst recommendations, not extra admission rules. The methods transfer to cognitive/health research, clinical-trial analysis, wearable evaluation and research coordination. The UK Life Sciences Jobs Plan supports broad digital/translational capability, not sleep-specific vacancies or professional clinical accreditation. Career context.

Next Actions and Questions to Verify

Before applying: Choose the sleep or appetite project within 181D; confirm personal degree equivalence, English condition and the exact 23 November/reference deadline. Use the Birmingham project link, not Warwick P-C1PBB, and complete EDI. Contact uob-mibtp@contacts.bham.ac.uk for administration and k.segaert@bham.ac.uk for scientific questions.

At interview: Ask how the sleep module fits the parent recruitment and study calendar; which sample, repeat visits and retention are feasible; which wrist/light devices and rhythm endpoints are intended; and whether any objective phase biomarkers are included. Confirm available MRI/blood data, treatment of mediation, adherence, season and missingness, joint-supervisor training and fixed participant rota.

Before accepting: Obtain written four-year international-fee and confirmed 2027/28 stipend terms, participant/device/research budgets, ethics/data permissions, placement travel arrangements and a realistic 52-week housing/immigration budget. A well-bounded finding that sleep explains little of the exercise response would still have scientific value.

Evidence and Sources

The saved recruitment material and earlier report do not confirm current acceptance, closing time or time zone. Programme, profile, funding, policy and cost details remain limited to the saved material; current vacancy status and policy were not verified. The prior selected-section reading for the first two papers and abstract-only scope for the third are retained; no new full-paper or supplement reading is claimed. The source label “Light pins” and the official outline’s generic light-data wording remain distinct.
