Andy undertook undergraduate training in Glasgow before moving to Edinburgh to start his training in Anaesthesia and Intensive Care. Whilst in Edinburgh he developed an interest in ICU-acquired infections, and studied for a PhD in critical care immunology and its impact on nosocomial infections supervised by Professors John Simpson and Timothy Walsh. He moved to Cambridge to complete his post-graduate training in Anaesthesia and ICM and to undertake post-doctoral research with Professor Edwin Chilvers. He has developed a number of diagnostics for nosocomial infection, including the host response test recently evaluated in the VAP-RAPID trial, and several pathogen-focussed molecular diagnostic platforms. He is currently a Wellcome Trust Clinical Research Career Development fellow at the University of Cambridge and Consultant in Intensive Care Medicine in the John V Farman Intensive Care Unit, Addenbrooke’s Hospital. He is the incoming deputy chair of the ESICM infection section.
