Dr Iain Marshall is a Reader at King's College London, and an NHS GP and partner in South London. He is a population health scientist with diverse research interests including using artificial intelligence to support health decision-making, research synthesis, and stroke and cardiovascular disease prevention.

Iain leads the Solace-AI project, a Wellcome Trust-funded international collaboration developing AI-driven systems to rapidly synthesise research evidence during climate-related health emergencies. Working with partners across Africa, Europe, and North America, SOLACE-AI aims to provide decision-makers and humanitarian organisations with timely, locally relevant evidence syntheses — particularly focusing on historically underserved communities affected by extreme weather events. He co-leads the RobotReviewer project, which uses machine learning to automate systematic reviews.

Iain leads the Stroke research group at King's, where his research focuses on how social determinants of health influence stroke risk, access to care, and long-term outcomes in diverse populations. Through the South London Stroke Register, he investigates disparities in stroke incidence and outcomes by socioeconomic status, ethnicity, and age, with particular interest in understanding how these inequalities have evolved over time, and drivers of differential access to cardiovascular disease prevention and care. He serves as the GP member of the Intercollegiate Stroke Working Party and is was on the guideline development group for the 2023 National Clinical Guideline for Stroke. He is Chief Investigator of the South London Stroke Register and of the NIHR Programme Grant: Improving the lives of stroke survivors with data.

Iain supervises PhD students in applied AI in health, health data science, and stroke epidemiology.
