My research at the school included data science on the MAP-CLD project, looking at the care and outcomes of patients with chronic liver disease who are admitted to hospital as an emergency. Earlier work in sub-Saharan Africa combined epidemiological and economic approaches to evaluate access to and quality of care, often working closely with clinicians, NGOs and governments. This included evaluations of complex interventions and development of new data collection methods, including standardised patients, in which I have particular expertise.
