Research Interests

Dee Mangin is a New Zealand family physician who is currently Professor and Director of the Primary Care Research Group at the University of Otago, Christchurch. She is also the David Braley Nancy Gordon Chair in Family Medicine at McMaster University, Canada.

Her interests are rational prescribing, and the influences of science, policy and commerce on the nature of care.

Expertise spans generation of clinical evidence using randomised controlled trials, the effects of pharmaceutical company promotion to consumers and physicians, effective medicine use in older age, innovative models of general practice care and effective incorporation of evidence into patient-centered practice.

She has been a member of the Pharmaceutical and Therapeutic Products Advisory Committee.
