Research Interests

  • Rheumatology
  • Cardiovascular care for rheumatoid arthritis


Dr. Barber completed an honors degree in microbiology and immunology (2002), a medical degree (2006), and internal medicine training (2009) at Dalhousie University in Halifax, Nova Scotia. She then pursued subspecialty medical training in rheumatology at the University of Toronto (2011). She then moved to Calgary to pursue additional research training in epidemiology and graduated with a PhD in Epidemiology from the Department of Community Health Sciences at the University of Calgary in 2016.

During her PhD she was supported by continuous funding from Alberta Innovates Health Solutions and she was also awarded a prestigious Vanier Canada Graduate Scholarship. Her PhD research was also supported by CIHR funding. For her PhD thesis she developed the first set of quality indicators (QIs) for cardiovascular care for rheumatoid arthritis.

Dr. Barber has developed nationally recognized expertise in quality measure development and over the last 5 years has been working extensively with the Arthritis Alliance of Canada to develop a framework for evaluating models of care for inflammatory arthritis (see key publications below).

In October 2015, Dr. Barber was hired as an assistant professor in the Department of Medicine, Cumming School of Medicine at the University of Calgary. She is also affiliated with the O’Brien Institute for Public Health and the McCaig Institute for Bone and Joint Health.
