I am Lead of the Cancer Epidemiology Research Group at the Centre for Public Health at Queen's University Belfast. I am Deputy Director of the Northern Ireland Cancer Registry. 

My research mostly focuses on the epidemiology and early detection of gastrointestinal cancers and conditions, including pre-malignant conditions. I have particular interests in:  

• Barrett's oesophagus and oesophageal adenocarcinoma (major ongoing studies include: PI of the Northern Ireland Barrett's oesophagus register; OCCAMS consortium sub-study investigator)
• Colorectal polyps and colorectal cancer (major ongoing studies include: NI Biobank Epi700 cohort; NI Bowel Cancer Screening pathology data analysis; Early-onset colorectal cancer studies). 
• Modifiable risk factors, such as smoking, alcohol and nutrition, in cancer risk and progression
• Gastrointestinal pathology diagnosis trends and concordance (member of the International Barrett's Pathology Working Group)

I have expertise in molecular epidemiology (incuding molecular pathology epidemiology) studies, statistical analysis of population-based disease registers and real world evidence, and systematic reviews of lifestyle factors and biomarkers in cancer risk and progression.

I place considerable emphasis on interdisciplinary research, and am affiliated to the Patrick G. Johnston Centre for Cancer Research at Queen's University Belfast.  I have previously spent time conducting research at Vanderbilt University, Nashville, TN, USA, Ulster University, and at the MRC-Human Nutrition Research centre in Cambridge, England. Since 2018, I am a Visiting Scientist with the Fitzgerald Lab at the Early Cancer Institute (formerly MRC Cancer Unit) at the University of Cambridge, to further enhance interdisciplinary research efforts in oesophageal cancer as part of a Cancer Research UK funded Career Establishment Award.
