She was a ministerially appointed member of the New Zealand Pharmaceutical and Therapeutic Products Advisory Committee (PHARMAC).
Her research specializations encompass rational prescribing, the impacts of science, policy, and commerce on healthcare, pharmaceutical policy, evidence-based medicine, primary care research methodologies, and patient safety. Current academic interests include multimorbidity and polypharmacy management, deprescribing interventions for older adults, innovative primary care delivery models, and enhancing generalist care value in education and health systems. Mangin has authored numerous influential publications, such as the highly cited "Feasibility study of a systematic approach for discontinuation of multiple medications in older adults: addressing polypharmacy" (2010, Archives of Internal Medicine, 856 citations), "Challenges and enablers of deprescribing: a general practitioner perspective" (2016, PLOS ONE, 251 citations), "International Group for Reducing Inappropriate Medication Use & Polypharmacy (IGRIMUP): position statement" (2018, Drugs & Aging), and "Maintenance or discontinuation of antidepressants in primary care" (2021, New England Journal of Medicine).
