Dr Moriarty's research has focused on the development of social roles, particularly within organisations, and the outworkings this has for individuals’ mental health and wellbeing.

This research includes ongoing mixed methods research on wellbeing and career perceptions among older workers; on social care staff wellbeing, role clarity and role ambiguity; analysis of wellbeing among informal caregivers and volunteers (see publications in American Journal of Public Health; Age and Ageing and International Journal of Epidemiology).

The research aims to improve people’s wellbeing by developing a knowledge base and appropriate interventions to target causes of mental ill-health at work, such as burnout and lack of role-appropriate training.
