Graham Francis Hassell Medley OBE (born 1961) is professor of infectious disease modelling at the London School of Hygiene & Tropical Medicine (LSHTM) and the director of the Centre for the Mathematical Modelling of Infectious Diseases there.^[1][2]

Medley was educated at Churcher's College and the University of York.

Medley's research is centred around the transmission dynamics of infectious diseases, and he has published on this for a range of different pathogens and hosts. He has a particular interest in the application of mathematical models to the development of policy, especially the interaction of disease transmission with societal and political processes.^[1]

He is one of the 23 attendees of the Scientific Advisory Group for Emergencies (Sage), advising the United Kingdom government on the COVID-19 pandemic, and is chair of the SPI-M modelling sub-committee.^[3] He also sits on the expert group of the UK's Infected Blood Inquiry, established to investigate how infected blood (and blood products) were used in treatment, in particular since 1970.^[4]

Since 2014, he has been a member of the Science board of reviewing editors.^[5]

Medley was appointed Officer of the Order of the British Empire (OBE) in the 2020 Birthday Honours for services to the COVID-19 response.^[6]
