"Inkfish Research Scientist (Medical) in Large Language Models"

About Us

The School of Life Course & Population Sciences is one of six Schools that make up the Faculty of Life Sciences & Medicine at King’s College London. The School unites over 400 experts in women and children’s health, nutritional sciences, population health and the molecular genetics of human disease. Our research links the causes of common health problems to life’s landmark stages, treating life, disease and healthcare as a continuum. We are interdisciplinary by nature and this innovative approach works: 91 per cent of our research submitted to the Subjects Allied to Medicine (Pharmacy, Nutritional Sciences and Women's Health cluster) for REF was rated as world-leading or internationally excellent. We use this expertise to teach the next generation of health professionals and research scientists. Based across King’s Denmark Hill, Guy’s, St Thomas’ and Waterloo campuses, our academic programme of teaching, research and clinical practice is embedded across five Departments.

About the role

We are looking for a Research Scientist (Medical) to join our team delivering the EMBRACE study, an innovative research project led by Professor Josip Car. EMBRACE is a visionary, multicomponent international research programme. The first of its kind in the world, supported by Inkfish with £35M core funds over six years. It is a global study of 60,000 participants, including 20,000 mothers, 20,000 infants and up to 20,000 partners. It brings together world-leading clinician scientists across six distinguished healthcare organisations, exceptional AI and technology companies, together with premier biotech companies, with the overarching aim to fast-track major scientific breakthroughs, revolutionise maternal and early childhood health through precision-personalised interventions, powered by a groundbreaking symbiosis of cutting-edge AI combined with human support.

The successful candidate will partake in the development of personalised, context-sensitive Large Language Models (LLMs) for health coaching. By delivering real-time, adaptive recommendations following exercise sessions and integrating multi-modal health and lifestyle data, the post-holder will play a key role in ensuring the medical validity and real-world relevance of the coaching recommendations. Collaborating closely with AI researchers, the individual will integrate medical knowledge into the LLMs, enhance their social intelligence (empathy, theory-of-mind), and evaluate multilingual and culturally sensitive deployments.

We are looking for an individual with a medical degree, a strong track record in public health and digital health research including peer-reviewed publications, an interest in LLMs as well as experience of using LLMs for healthcare research.

The post is based in the Faculty of Life Sciences and Medicine, and will be closely affiliated with the Informatics Department in the Faculty of Natural, Mathematical and Engineering Sciences.

This is a full time post (35 hours per week), and you will be offered a fixed term contract until 31/07/2029.
