Research Interests

Description Of Research Interests

My two major research themes are Inflammatory Bowel Diseases (IBD) and the Stomach. Regarding IBD, my interests are around Quality of Life for patients with IBD including fatigue, psychological effects and non-inflammatory GI symptoms as well as post-operative prophylaxis of Crohn's disease. Regarding the stomach my themes are Helicobacter pylori infection, treatment, antibiotic resistance rates and eradication as a means of prevention of stomach cancer. In addition, upper Upper Gastrointestinal Tract Bleeding is a further focus. I also have done some research on the GI complications of cancer therapies.
