Dr Wan is an NIHR Clinical Lecturer in Intensive Care Medicine and Anaesthesia with the Critical Care and Perioperative Medicine Research Group within the Faculty of Medicine and Dentistry at Queen Mary University of London. She is a dual specialty registrar in anaesthesia and intensive care medicine in London.

Dr Wan completed her undergraduate medical training and PhD at Nottingham University. Her research is centred on the epidemiology of patient populations needing acute healthcare, with a focus on socioeconomic and ethnic determinants. She also leads studies in data science using electronic health record data to investigate persistent critical illness and long-term outcomes following critical care.

Dr Wan co-leads the Research and Audit methodology module for the Critical Care Medicine MSc. She is an editorial fellow for the British Journal of Anaesthesia and sits on the editorial advisory board for BMJ Open.


I lead epidemiological and data science studies aimed at identifying risk factors for acute illness and hospitalisation, development of persistent critical illness, and long-term outcomes following critical care. This research aims to better understand the interaction between acute declines in health and development of long-term illness. It seeks to identify opportunities to intervene and address determinants of long-term poor health, particularly for disadvantaged patient groups.
