Metabolic regulation of neural circuits controlling cognition and metabolism
About the Project
How do ageing and obesity affect the brain and behaviour? This PhD project will investigate how the metabolic hormone insulin regulates neural circuits that control attention, learning, physical activity, and feeding behaviour. The research will focus on the basal forebrain, a key brain region involved in cognitive function that becomes less effective during ageing and in obesity.
The project will examine how insulin normally enhances activity within basal forebrain circuits and will test whether targeting downstream signalling pathways can restore brain function when insulin signalling is impaired.
The successful candidate will receive training in a wide range of modern neuroscience approaches, including behavioural analysis, multiphoton imaging, electrophysiology, and pharmacology.
This studentship is funded by the John Findlay Scholarship and is open to UK applicants only. The award covers full tuition fees and a maintenance stipend and is available for students starting in the 2026/27 academic year within the School of Biomedical Sciences.
You will join a supportive, collaborative and well-funded research team with expertise spanning behaviour, metabolism, electrophysiology, imaging and ion channels. The project will be based in the Johnston lab in the School of Biomedical Sciences at the University of Leeds in collaboration with the Filippi and Lippiat labs.
The student will also benefit from being part of the wider neuroscience research community at Leeds, providing opportunities for collaboration, seminars, and training.
We welcome applicants from diverse academic backgrounds including neuroscience, psychology, biology, biomedical sciences, engineering, or related disciplines. Curiosity, motivation, and enthusiasm are important attributes of a successful candidate. Interested candidates are encouraged to contact Dr Johnston to discuss the project further.
Your work could help uncover new ways to protect brain function in ageing and metabolic disease.
