Research interests span Sociology, Anthropology, Gender Studies, and Sexualities. Interests at the moment are focused in the area of the sociology and anthropology of religion, specifically the experiences of minority religious groups in Ireland. 

Dr O'Brien is generally interested in exploring the relationship between majority/minority cultures, whether that manifests itself through religion, ethnicity, gender, or sexuality. Key themes throughout her research are the role of tradition and memory in identity, and the intersections and conflicts of religious, ethnic, and national identities.

Ongoing current projects include: exploring Irish Mormonism in a global mileau, synthesising the study of religions in Ireland, and exploring the role of women in modern Mormonism (funded by and in conjunction with the Maxwell Institute of Brigham Young University), and the supervision of postgraduate projects in the areas of identity and culture
