PhD Studentships x2 – University of Nottingham, School of Medicine.

Programme title: Understanding and enhancing the physiological resilience of older adults to improve health-span: a focus on skeletal muscle.

Principal supervisors: 

PhD 1 - Prof Philip Atherton (School of Medicine) – philip.atherton@nottingham.ac.uk 

PhD 2 - Prof Bethan Phillips (School of Medicine) – beth.phillips@nottingham.ac.uk 

Funded by the Dunhill Medical Trust (https://dunhillmedical.org.uk/) as one of their Multiple PhD Studentship Awards, we have two fully-funded (stipend at UKRI rates, PhD fees (for UK nationals only) and research costs), three-year full-time PhD’s available, each to start on the 1^st October 2024. 

Programme description: Loss of resilience describes enhanced vulnerability to, and impaired recovery from stress events when compared to a robust [youthful/healthy] state; and is commonly encountered with advancing age. With ageing populations around the world, and the associated rise in years spent in ill-health, there is an urgent need to understand the mechanisms underpinning this loss of physiological resilience, and potential strategies to mitigate these declines. Although a recent national GIRFT (Getting It Right First Time) report suggests that improving frailty management could save the NHS >£600-million/year, furthering understanding of the biological mechanisms driving reduced resilience to inform on precision mitigation strategies (i.e., for the right people at the right time) could in fact have a much bigger impact. This impact would favour not only on healthcare systems but also older individuals, their support networks and society as a whole. Evidence suggests that skeletal muscle deterioration, including metabolic and functional decline, is a core driver of reduced resilience in older adults both with and without disease. Indeed, skeletal muscle weakness is at the fore of both frailty (the clinical term encompassing loss of resilience) and sarcopenia (age-associated losses of muscle mass and function) definitions. A devastating consequence of reduced resilience is that the time people spend in good health (their health-span) is now much shorter than overall lifespan; an issue that we aim to help address through these PhD’s.

PhD descriptions:

PhD 1 – Drug repurposing is an emerging avenue of research in the field of Geroscience; a field whose stated aim is to “accelerate research into the basic mechanisms driving ageing which could lead to improved clinical interventions”. Based at the University of Nottingham Medical School at Derby (UNMSD; Royal Derby Hospital Centre), this PhD is focussed on exploring the impact of an already-licensed mechanistic target of rapamycin (mTOR) inhibitor (which has been shown to attenuate sarcopenia in animal models of ageing) on muscle growth and function in both community-dwelling older adults and orthogeriatric patients. Results from this PhD will inform on the potential of mTOR inhibition to enhance the resilience of older adults, not only in relation to skeletal muscle but also other organ systems for which favourable pre-clinical data is emerging (i.e., the immune system). As is the case for all of these PhD’s, the successful candidate will learn a wealth of skills relating to human physiology studies/clinical trials and state-of-the-art wet-lab techniques.

 PhD 2 – In addition to rehabilitation, which has long been employed as method to enhance recovery from clinical stress events, there is burgeoning clinical and research interest in prehabilitation, an approach employed to prepare individuals for these events. Based at the University of Nottingham Medical School at Derby (UNMSD; Royal Derby Hospital Centre), this PhD will consider the importance of, and methods for the preservation of muscle mass and function in older patient cohorts. With elective surgery a clear and common example of a stress event encountered by older adults, and recognising that physiological resilience is not just preparedness for stress events but also the ability to recover from them, this PhD will focus on practicable pre- and rehabilitation strategies in older surgical patients. Exploring the interaction between novel contractile strategies and nutritional intake, results from this PhD will provide an evidence-base for strategies to be implemented as an adjuvant to standard care in the peri-operative period of older surgical patients.  

Both of these PhD’s will benefit from the expertise and experience of multi-disciplinary supervisory teams comprised of discovery scientists and clinical academics.

Further information:

Applicants should have either:

• a minimum of a 2.1 in a relevant undergraduate degree (e.g., Exercise Science, Physiology, Biology, Biomedical Sciences (non-exhaustive list)), OR
• a minimum of a 2.2 undergraduate degree and a relevant Master’s degree.
