Dr Khoo Hwee Sing
Senior Research Analyst
BBA, MComm,
PhD (Management & Organisation)

​Hwee Sing adopts a multi- disciplinary approach in her work, and believes it is essential to bridge research and practice for better sharing, integration, and application of knowledge. This motivates her to view research through different theoretical lenses, and incorporate phenomena into research for educational and practical applications. At HOMER, she is involved in projects related to the development and improvement of curriculum and clinical rotati​ons in undergraduate and graduate medical education. This involves analysing data from all stak​​eholders in the healthcare process to provide valuable inputs for curriculum design, and for the improvement of the patient-doctor communication process.
Hwee Sing holds a PhD in Management and Organisation from the National University of Singapore, and brings to HOMER experience in conducting research on primary healthcare, leadership, as well as consulting on organisational change.

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.

Mr Lim Yong Hao
Principal Research Analyst
BSocSc (Psychology),
MSocSc (Psychology)

Yong Hao adopts a pragmatic approach in his research on HPE. This renders a variety of research methods for answering different research questions, and for drawing out the practical implications of completed research projects. In HOMER, he is involved in research and evaluation projects related to undergraduate and graduate medical education. These projects include analysing assessment data collected by the various residency programmes to better understand residency training; developing faculty evaluation tools; and evaluating the impact of training programmes.

He completed his Master of Social Sciences (Psychology) with a concentration in Quantitative Methods at National University of Singapore.
