Dr Watson is a Research Fellow in the Centre for Public Health, Queen's University Belfast. Her research interests primarily focus on evaluating interventions aimed at improving the oral health of older adults, particularly those dependent on care. She is also interested in exploring the impact of oral health status on dietary intake and nutritional status of older adults in large population-based cohort studies, and using data collected as part of national food consumption surveys.
