Professor Patrick Kennedy

Professor Kennedy was promoted to the position of Professor of Translational Hepatology in August 2019. In his time at Queen Mary University of London, he has delivered world leading translational research in chronic hepatitis B (CHB) virus. He established a highly successful young adult CHB clinic, which is now a flagship service for Barts Health, distinguished by innovation and scientific excellence. This led to the publication of seminal work on the management of CHB in young people, (Kennedy et al., Gastroenterology 2012, Mason et al., Gastroenterology 2016, Le Bert et al., Gastroenterology 2020).

Furthermore, this research has provided the impetus to consider earlier therapeutic intervention as a strategy to prevent the development of chronic liver disease and liver cancer (Gastroenterology papers, IF>20, having >100 citations each), which has formed the basis of a change in national (NICE) and international clinical practice guidelines for CHB (EASL 2017). Professor Kennedy is now investigating novel viral markers and immune aspects of emerging treatment strategies and developing less invasive liver sampling in the setting of novel therapeutic approaches (Gill et al., PloS Pathog. 2016, Gill et al., Gut 2018).

Community Advisory Board

The SHARE Collaborative Community Advisory Board will provide a platform to ensure meaningful inclusion and authentic co-production of the research agenda with the local community, with board members being remunerated for their time and expertise. The board will inform every stage of the research process, from comment and advising on research topics, considering the direction, volume, diversity and applicability of proposals for research as well as  acting as local champions. The board will provide advice on recruitment of research participants as well as the dissemination of findings. SHARE will train and employ peer researchers and aim to have a community co-author on research publications. We believe this approach will ensure our research remains relevant to the community in which it is conducted and reflective of Queen Mary and Barts Health values.
