Profile

 

Dr Kennedy undertook undergraduate medical training at University College Dublin and completed his post-graduate medical training in Gastroenterology & Hepatology in London. He completed his doctoral research with Professor Antonio Bertoletti at The Institute of Hepatology, UCL in 2006. During his doctoral research he investigated T cell responses in chronic hepatitis B and C. He was appointed as a HEFCE Clinical Senior Lecturer in Hepatology at Barts and The London SMD, QMUL in 2009 and has since progressed to Reader in Hepatology based on his research in chronic hepatotropic viral infections.

His primary research focus/interest is in Hepatitis B virus (HBV) within a translational platform. He has a special interest in liver disease in young people, specifically HBV; he set up and runs the dedicated young adult liver service at The Royal London Hospital. He is widely published in viral liver disease and his work in the field is known internationally. He has produced novel work redefining disease categorisation in HBV, the foundation for the re-evaluation of treatment candidacy in Chronic Hepatitis B (CHB). Developing these themes, an important focus of his current work is individualized treatment strategies for CHB. His research also investigates factors driving the development and progression of liver disease and cancer in CHB.

He is a member of the viral hepatitis clinical guideline committee for NICE and provides expert opinion for the United Kingdom Advisory Panel on blood-borne viruses. He is the Hepatology lead for the Gastroenterology and Hepatology Section at the Royal Society of Medicine. In addition, he is a key opinion leader in viral liver disease and a member of expert advisory panels for Gilead, Roche and BMS. He is regularly invited to chair and speak at national and international meetings and regularly reviews grant applications in addition to manuscripts for a number of journals. More recently he is the chief/principal investigator for a number of investigator-led and commercial phase 1, 2 and 3, clinical trials in HBV therapy. This clinical trial portfolio dovetails Dr Kennedy’s longstanding research interest and publication record, the ultimate goal of which is HBV cure.

PhD Supervision

Dr Kennedy supervises doctoral MD and PhD students along with BSc and MSc students as the per the Institutional programs at the Blizard Institute

Doctoral students

Dr Upkar Gill (Uppy) is a Wellcome Trust funded Clinical Research Training fellow and Honorary Registrar in Gastroenterology/Hepatology. His PhD research is co-supervised with Professor Mala Maini in collaboration with Professor Antonio Bertoletti, both of whom Dr Kennedy has a long-standing successful research partnership with. He originally started working with Dr Kennedy as an NIHR funded Academic Clinical Fellow before successfully securing his own funding with a WT fellowship. He has been involved with a number of projects spanning Dr Kennedy’s research themes but his primary research focus is investigating methods of harnessing the immune response in CHB to optimize current treatment strategies by probing NK and T cells interaction in vivo, in order to delineate optimal treatment regimes and end-points. He is an honorary research fellow at Duke-NUS Graduate Medical School, Singapore, where he has been working in Professor Antonio Bertoletti’s lab. He has published and presented work, obtaining prizes, at a number of national and international meetings.

 

Dr Navjot Hansi (Jyoti) is a Clinical Research fellow and Honorary Registrar in Gastroenterology/Hepatology. Her doctoral research is also co-supervised with Professor Mala Maini. She has been investigating the expression of inhibitory receptors on NK cells in CHB infection. The main focus being on the inhibitory receptor, LAIR, in conjunction with its ligand, collagen to determine whether the expression is involved in constraining liver fibrosis. In addition she is involved in projects to determine the role of quantitative HBsAg in non-inflammatory phases of CHB, to further delineate the use of the marker in disease progression. She has also been leading an industry sponsored project to determine management strategies in UK Hepatology centres following recent NICE guidance.

 

Dr Grace Dolman is a post-doctoral research fellow and Honorary Registrar in Gastroenterology/Hepatology. She undertook her doctoral PhD training at the NIHR Nottingham Digestive Diseases Biomedical Research Unit (www.nddcbru.org.uk), supervised by Dr Neil Guha. Her research focused on identifying tissue biomarkers to predict progression to clinical outcomes in patients with advanced fibrosis secondary to chronic hepatitis C infection. She has presented her work at international conferences and undertaken the Nottingham translational postgraduate research training programme. She is now working on Dr Kennedy’s NIHR RfPB programme, with his dedicated research nurse, Louise Payaniandy. This national research programme is centred on the use of quantitative HBsAg in disease assessment.

 

Dr Kennedy also successfully supervises BSc and MSc students on an annual basis. These students undertake small projects in relation to Dr Kennedy’s outlined research themes.
