Professor Wark's research interests are; airway inflammation in the context of chronic airways disease, innate immunity, the role of infection in chronic airways disease and translational clinical trial design. His group has developed expertise in identifying respiratory viruses in airway secretions and developing an in-vitro cell culture model of the airway epithelium that we use to model the effect of infection and inflammation. His research focuses upon factors that increase susceptibility to virus infection in asthma, COPD, Cystic Fibrosis and bronchiectasis. Characterising airway inflammation and innate immune responses in chronic airways disease and applying this to clinical care, as well as the development of precise individualised management strategies.
