Dr Mary Lee
Principal Research Analyst
BA, MA (English Language),
PhD (Communications)

Mary is a communication scholar who takes an interpretivist stance in her research. As a researcher in Health Professions Education (HPE), she has a special interest in investigating the role of communication in advancing or impeding interprofessional collaboration and learning. Consonant with healthcare professionals who endeavour to be collaborative in their work, Mary works to performing interdisciplinarity through her research and in the process, expanding her knowledge of qualitative research perspectives and methods. Her current projects include a phenomenological study on what doing leadership means for emerging leaders in healthcare settings and an analysis of the discourses occurring at interprofessional team meetings.

She values communication as a vehicle for change and reflexivity in one’s research, and takes a critical culture perspective to communication practice and scholarship, drawing on the Culture-Centered Approach to communication as well as the work of the Frankfurt School thinkers, Michel Foucault and scholars in Critical Discourse Analysis. Her publications can be found in Public Relations Inquiry and Public Relations Review. She has taught public relations writing and theory at the Department of Communications & New Media, National University of Singapore.
