Human Behaviour Models as Digital Biomarkers for Cognitive Function (PhD Studentship) University of Edinburgh in United Kingdom

This PhD studentship at the University of Edinburgh, offered through the UKRI AI Centre for Doctoral Training in Biomedical Innovation, focuses on developing advanced human behaviour models as digital biomarkers for cognitive function. The project aims to leverage recent advances in artificial intelligence and deep reinforcement learning to create mechanistic models that capture how cognitive decline manifests in observable human behaviour. These models have the potential to revolutionize the measurement of cognitive function, improve the specificity of tests for conditions such as mild cognitive impairment and Alzheimer’s disease, and enhance assistive technologies for individuals experiencing cognitive decline.

Students will gain cross-disciplinary experience in cognitive neuroscience and machine learning, working at the intersection of computational modelling, health informatics, and translational research. The project involves developing and testing human behaviour models for selected tasks, investigating their ability to capture empirically observed effects of cognitive function variations, and using these models to estimate cognitive function directly from behavioural data. The translational potential includes direct applicability for measuring and monitoring cognitive function, as well as integration into adaptive assistive technologies for dementia and age-related conditions.

The supervisory team includes Dr S Ramamoorthy, with project partners such as NHS Borders, providing opportunities for real-world impact and collaboration. The studentship is fully funded for four years, covering tuition fees, a generous stipend (£20,780 in 2025/26), and an individual budget for travel and research costs. Additional allowances for sick pay, maternity leave, and other purposes are available, and eligibility is open regardless of nationality or domicile.

Applicants should have a strong academic background in computer science, neuroscience, biomedical engineering, psychology, or related fields, with experience or interest in AI, machine learning, or computational modelling. International applicants may need to provide proof of English language proficiency. The application deadline is January 20, 2026, and candidates are encouraged to apply via the Centre’s website, following the provided guidance and submitting all required documentation.

This project offers a unique opportunity to build a rare cross-disciplinary skillset, contribute to cutting-edge research, and make a meaningful impact on the lives of individuals affected by cognitive decline.
