Dr Stephen Aston

Wellcome Trust Clinical PhD Fellow

Areas of interest

Management of pneumonia in low-resource settings; respiratory infection in HIV-infected adults


Stephen completed undergraduate and core medical training in Birmingham. Having spent a year in Oxford working on phase 1 clinical vaccine trials he took up a clinical research fellow position at Liverpool School of Tropical Medicine and was initially involved in large collaborative project investigating the pathophysiology of severe pandemic influenza. He started specialist registrar training in infectious diseases and general internal medicine in 2010 and in 2012 secured a Wellcome Trust Clinical PhD Training Fellowship to study pneumonia in Malawian adults.


His mains research interests are the diagnosis and management of severe respiratory tract infection in low-resource settings, particularly in HIV-infected adults. In his current PhD project he is recruiting a large prospective cohort of adults hospitalised with pneumonia in Malawi with the aim of identifying factors predictive of adverse outcome that may then inform patient triage and early management strategies.
