My research is focused on 2 main questions: 1. What are the molecular factors that drive and maintain the abnormal mucosal inflammation in Crohn’s disease (CD) and Ulcerative Colitis (UC)? 2. How do we translate this understanding to develop new, and to improve current, medical treatments?
Crohn’s disease (CD) and ulcerative colitis (UC) are common chronic inflammatory bowel diseases (IBD) with significant impact on morbidity, mortality and socio-economic costs. The global prevalence is increasing sharply with projected global disease burden of 20-30 million IBD cases by 2025. Present best therapies are based on the narrow principle of inhibiting downstream inflammatory pathways (eg, cytokines and inflammatory cell migration). Complete mucosal healing (total resolution of inflammation and restoration of full mucosal restitution) however, is achieved only in 50% in our best treatment. My work is focused on identifying and developing novel therapeutic approaches in IBD.
My overarching research aim is to translate new knowledge of immune and inflammatory mucosal mechanisms into new therapeutic approaches in IBD. I work very closely with dedicated IBD clinicians, biologists, immunologists and drug development teams with a strong focus on direct studies on human IBD along with in vivo colitis work. Major mechanistic themes are:
- Gut derived mucosal damage-associated molecular patterns (DAMPs)
- Mitochondrial dysfunction and ROS-signalling
- Metabolic programing of the mucosal immune response
I trained in Medicine in Glasgow (MBChB 1997 and MRCP 2000), and moved to Edinburgh to undertake my PhD with Jack Satsangi (2000-2003). I completed my specialty training in gastroenterology and internal medicine in Edinburgh (2003-2008) and was awarded an MRC Clinician Scientist Fellowship award (2009-2015). During this time, I trained under Balfour Sartor in University of North Carolina, Chapel Hill, USA (2009-2010) focusing on mucosal immunology in IBD, and moved to the MRC Centre for Inflammation Research in 2011 to establish my laboratory here.
I continue to care for individuals with IBD at the Western General Hospital and I lead the Edinburgh IBD Science Group (@Edin_IBDScience), a multidisciplinary group of researchers and scientists in Edinburgh with an aim to translate our scientific work into new treatments in IBD.
