Dr Tom Fletcher

Reader in Emerging and High Consequence Infectious Diseases and Director of Global Health Trials Unit.

After completing undergraduate training at University of Leeds, Tom undertook his general duties in the Defence Medicine Services and then higher specialist training in Liverpool in Infectious Disease and General Internal Medicine. He was seconded to the department of Pandemic and Epidemic Diseases at HQ WHO for a year before the 2013-15 EVD outbreak in West Africa, during which he and colleagues from the WHO clinical team led a step change in Ebola case management. For his Ph.D. he undertook a Wellcome Trust fellowship investigating the interaction of immune response, viral load and clinical course in a cohort of patients with Crimean-Congo Hemorrhagic Fever (CCHF) in Turkey. During the COVID-19 pandemic, he returned to HQ WHO clinical team and was deployed to South Korea before returning to support the UK NHS response.

Tom is a senior investigator within the AGILE trial platform, leading AGILE International and the laboratory pillar. He is the candidate chief investigator on 2 early phase trials of novel therapeutics in COVID-19 in the UK and South Africa.

His research at LSTM is mainly focussed on High-Consequence Infectious Diseases, where he is the Co-Director of the ACTIVE platform - ACcelerating Therapeutics and dIagnostics in Viral HaEmorrhagic fever. He has active research programmes in Turkey, Sudan and West Africa.
