About our team

We strongly believe in doing research with the communities who are affected.

Our research program focuses on the management of chronic diseases, patient-reported outcome measures, shared decision making, as well as the synthesis and application of evidence-based knowledge in clinical practice.

Dr. Karine Toupin April

Dr. Karine Toupin April is the principal investigator and her career journey was inspired through personal experiences with chronic disease as a child. She trained as an occupational therapist and continued with a Master’s degree in rehabilitation and a PhD in public health and epidemiology. She met patient partners early in her training through the Canadian Arthritis Network instilling an inclusive and collaborative way of doing research. Our team is made of research staff, a patient and family advisory committee, collaborators, and partners.

Alexandra Sirois

Alex Sirois first developed JIA at the age 7. It took 3 years, and a referral to Sick Kids in Toronto, before she was properly diagnosed. Living with JIA has shaped how she views health care, as she gains a fuller understanding of the enormous gaps that her and others with inflammatory arthritis (IA) face, the stigma of living with IA, and the limited information on how to live a full, meaningful life. This drives Alex to help change the face of arthritis and improve the quality of life of individuals with IA. Alex has seen firsthand that the more she gives to the arthritis community, the easier it was to accept and embrace who she is and thrive. She holds a Bachelor of Physical Education from Laurentian University, and a Master of Science from McGill University. Alex works full-time in Public Health, part-time as a research assistant and is an active patient partner in research. She enjoys exercising, cooking, and traveling (food touring).

Naomi Abrahams

Naomi Abrahams is a PhD student and student-researcher in the School of Social Work at the University of Ottawa, Canada. She holds a bachelor’s degree in Child, Youth and Family Studies (2019) from the University of Guelph as well as a Master of Social Work (2021) from the University of Ottawa. Her research interests include children’s rights, domestic violence and knowledge-based injustices. Being a patient partner enables her to utilize her knowledge and experience, as both a researcher and respondent, to participate in research promotion that values lived experience.
