Dr Gavin Barlow


Senior Clinical Lecturer in Infection

Role at Hull York Medical School

Gavin Barlow is a Senior Clinical Lecturer at Hull York Medical School at the University of York and an Honorary Consultant in Infection at Hull University Teaching Hospitals NHS Trust. He is also the phase III (final year) academic lead for Medicine at Hull York Medical School.


Gavin qualified in medicine at Leicester University, UK in 1993 and trained in infectious diseases and general internal medicine in Leeds, Sheffield and Dundee, including a two-year research training fellowship at the University of Dundee. He commenced as Senior Clinical Lecturer at HYMS and the University of York, UK on 1st August 2019, having previously been a full-time Consultant Physician in Infection at Hull University Teaching Hospitals (HUTH) since November 2004. Between 2005 and 2018, he led a successful antimicrobial stewardship programme at HUTH that benchmarks well nationally. He was the British Society for Antimicrobial Chemotherapy (BSAC) Officer for Stewardship and Surveillance 2016-2019 and is the inaugural research editor of JAC Antimicrobial Resistance.

GB’s main clinical interests are orthopaedic infection, outpatient parenteral antibiotic therapy (OPAT), and the management of complex bacterial and healthcare-associated infections. GB was awarded Fellowship of the Royal College of Physicians, London in 2009. He has more than 80 publications, is a co-editor of the infection chapter in Clinical Medicine, Kumar & Clark, was a chapter editor for BSAC’s e-book Antimicrobial Stewardship: From Principles to Practice and co-lead of week 2 of the massive open on-line course (MOOC) in antibiotic stewardship. He was also a member of the implementation sub-group for the most recent version of Start Smart Then Focus.


Gavin is a member of the Experimental Medicine and Biomedicine research group.

Research interests are broad, but predominantly focus on the epidemiology and clinical care of severe infections, common in the NHS (see publications). Ongoing research includes projects that focus on: the effects of combination antibiotic therapy, including beta-lactam combinations, on antibiotic resistant bacteria; an assessment of the impact of a dedicated Clostridium difficile infection ward on patient outcomes; a systematic review of systematic reviews about the impact of procalcitonin on antibiotic prescribing; an evaluation of Tedizolid in clinical practice; and the impact of OPAT on the gut microbiota. Working cross-site between the University of York and HUTH provides considerable opportunities for clinically focused, inter-disciplinary translational infection research.
