Research Expertise

Description

I have been involved in basic and translational research for all of my professional career and this interest began when I undertook my MD research work in the Sir Patrick Dunn Research Laboratory in St James's Hospital and concomitantly completed a taught MSc in Molecular Medicine. There are a number of strands to my research and these can be consolidated into four main areas. 1. Inflammatory Bowel Disease As a Gastroenterologist, IBD one of the main clinical challenges encountered and causes major morbidity to those affected. I am involved in a number of research projects and have published widely in this area over the years. Early on in my career, I had two high impact publications in Gut, the second highest impact factor GI Journal (IF 17). One related to IBD -related metabolic bone disease (osteopaenia, osteoporosis and fractures), a previously little recognised sequela of IBD and the effects of biologic therapy thereon. I have continued this research as a major theme over the past 15 years, and have had numerous publications in this area, including a 10-year follow up study, that has been presented at international meetings, and is currently in preparation for publication. This research has also produced one MD thesis, which I supervised. The second publication alluded to above, as joint first-author related to the socioeconomic impact of IBD on affected patients and bias / barriers they encounter in the insurance and life assurance market. This article, also published in Gut, gained a lot of media attention at the time, particularly in the UK where it was published and the Netherlands where the work was undertaken, as patient IBD groups highlighted the results of the study to the media, to highlight the unjustified barriers they encountered while looking for life assurance or health insurance. I have also spoken to Irish IBD patients (ISCC) about this in numerous occasions and have been an advocate on their behalf. As part of an international research group, I was involved in the Gemini trials, which looked at the efficacy of a novel biologic therapy, called Vedolizumab in Crohn's disease and Ulcerative Colitis. Both of these studies were published in the New England Journal of Medicine in 2013 and this drug is now in everyday use. I am involved in a number of other areas of research in IBD, including therapeutic drug monitoring, novel therapeutics and more recently the potential of nanotechnology for drug delivery in IBD. 2. Pancreatic Disease and Interventional Pancreatobiliary Endoscopy. I am part of the Multidisciplinary Pancreatic Research group in TUH and am involved in, and PI in a number of ongoing projects. I have a special interest / expertise in Pancreatobiliary Endoscopy and have established a national tertiary referral practice for complex pancreatic intervention, including endoscopic cyst-gastrostomy. I have an international reputation in this field and am an active member of the UK and Ireland EUS Society and the European Society for Gastrointestinal Endoscopy. As part of an international collaboration with a number of centres in the UK, I recently published on the use of a novel device for EUS-guided drainage of pancreatic fluid collections (pseudocysts / walled-off necrosis). Other areas of research I am leading In TUH in this field, include the effects of Chronic Pancreatitis (CP) on vascular risks in patients thus affected and are also investigating the undiagnosed burden of CP in at-risk populations. This work is forming the basis for a MD thesis, and the MD student is currently on the books in the College. We also lead ongoing research in pancreatic cystic lesions (PCLs), particularly the precancerous PCL called IPMN (intraductal papillary mucinous neoplasm) and one MD and one PhD student have been recruited to undertake further research in this area, in collaboration with Dr Stephen Maher, Usher Assistant Professor in the TTMI. 3. Biomarkers in GI disease: 4. Coeliac disease.
