Dee Mangin is currently Professor of General Practice at University of Otago, Christchurch and at McMaster University, Canada. She is Director of the Primary Care Research Group at the University of Otago, Christchurch. She previously held the David Braley Nancy Gordon Chair in Family Medicine for 10 years at McMaster University, Canada, and has been an active adviser in Canada during this time on health system improvement and operationalisation in primary care.

As well as undergraduate and postgraduate teaching, Dee’s overarching interests are the influences of science, policy and commerce on the nature of care. Her interest in research is as a lever for advocacy, to support and improve health care for patients that will best enable a life worth living, on their terms.

Dee has wide clinical research experience in primary care, including observational and interventional quantitative research methods and community RCTs of innovative models of care. Topics areas include innovative systems of care (incorporation of patient priorities and preferences into care, complex interventions for older adults, extended models of primary care), rational medicine use (antidepressants, antibiotics, deprescribing trials of the reduction of single medicines as well as deprescribing multiple medicines in older adults).

Dee supported capacity building for primary care research through the development and inception of the David Braley Primary Care Research Collaborative while Associate Chair, Research at McMaster DFM and supporting capacity development for General Practice and General Practice research continues to be a strong interest. She is happy to be contacted by anyone interested in developing their primary care research role or skills.
