Dr. Barnabe’s research program, ‘Arthritis Care for Indigenous Populations’, has contributed knowledge on the epidemiology of arthritis and contemporary outcomes of inflammatory arthritis conditions for Indigenous people. In response to the identified accentuated disease burden, she co-develops promising health services interventions to bridge the care gaps that exist, and leads delivery of curricular initiatives for rheumatology practitioners to support the provision of culturally safe arthritis care environments. Dr. Barnabe is also conducting research to reduce and resolve arthritis outcome inequities by improving guideline development and their implementation. She is collaborating with partners in primary care, rheumatology, and patients to improve access to ambulatory care services for arthritis concerns to reduce avoidable acute care use.

Dr. Barnabe has received several national awards, including a CIHR Canada Research Chair in Rheumatoid Arthritis and Autoimmune Diseases (Tier 2, 2018-2023), the CIHR Killam Emerging Research Leader Award (2018) and is a member of the College of New Scholars, Artists and Scientists of the Royal Society of Canada (2018).
