Dr James Stewart is stood in his lab looking into the camera

James Stewart

James Stewart holds the Chair of Molecular Virology at the University of Liverpool where he is also Head of the Department of Infection Biology and Microbiomes. He is an expert virologist with over 25 years experience in establishing and using mouse and small animal models of virus infection, molecular biology and immunology. The early part of his career was spent studying pathogenesis, with a particular focus on the herpesvirus family. he developed murine gammaherpesvirus in mice as a model for studying authentic host-virus interactions, exploiting the power of virus reverse genetics and KO mouse technology. More recently he has moved to focus on pathogens such as SARS-CoV-2. influenza A, respiratory syncytial virus and human rhinovirus. He has developed an integrative toolkit and pathway with which to do this. He uses conventional and molecular techniques to analyse the course of virus infection combined with big data techniques and informatics to relate the function of viral determinants with host defence responses. While still studying pathogenesis, the COVID epidemic has changed his focus, and a large part of his research is developing novel therapeutics and interventions for SARS-CoV-2 and other respiratory pathogens. He is currently leading small animal preclinical models of COVID-19 at the University of Liverpool. Prof Stewart has published over 120 peer-review manuscripts (h = 45). He leads and co-leads large multicentre research grants. Research funding has been secured from UK Biotechnology and Biological Sciences Research Council (BBSRC), the Medical Research Council (MRC), Innovate UK, UK Ministry of Defence, The Wellcome Trust, National Institutes for Health (NIH), and pharmaceutical companies. He has supervised >30 graduate students and mentored 20 PDRAs. He regularly sits on National and International funding award panels and is an academic editor for PLoS ONE. He is a member of the WHO COVID-19 animal models group. He Chairs the University Animal Welfare and Ethical Review Body.
