Our Members

The following people participate in our network by contributing their time and expertise to be members of our advisory board, committees and working groups. Their guidance helps ensure that the OHTN conducts and supports the most innovative and scientifically rigorous HIV research with the potential to improve the health and well-being of people with HIV in Ontario.  We thank them for their contribution.



Janet Raboud
Dr. Janet Raboud has a PhD in biostatistics and is an Associate Professor in the Dalla Lana School of Public Health Sciences at the University of Toronto and an Affiliate Scientist in the Division of Infectious Diseases at the University Health Network. She has been involved in collaborative research in HIV for many years, both in clinical research and in epidemiology and has over 100 published papers in peer-reviewed journals. She currently holds a Career Scientist Award from the Ontario HIV Treatment Network (2005-2014) and is involved in the Ontario Cohort Study as a member of the Scientific Review Committee, Clinical Working Group and Data Working Group and is Principal Investigator or co-investigator on a number of OCS protocols.
Anita Rachlis
Dr. Rachlis is Professor, Department of Medicine, Division of Infectious Diseases, University of Toronto, ON. She has worked in HIV/AIDS care since 1983 at Sunnybrook Health Sciences Centre and has been involved in clinical research in the treatment of opportunistic infections and antiretroviral therapy. She received a Council Award in February 2002 from the College of Physicians and Surgeons of Ontario for her work in the care and treatment of HIV patients. She facilitated the development of the Canadian HIV/AIDS Primary Care Physician Mentorship Program (CHAMP) and the HIV Ontario Observational Database (HOOD) which was the forerunner of the Ontario Cohort Study (OCS). Dr. Rachlis is a member of the Board of Directors of the Ontario HIV Treatment Network (OHTN); participates in the Canadian HIV Trials Network; and serves as a scientific reviewer for granting agencies. She has been a member of the Ontario Advisory Committee on HIV/AIDS since 1991, co chair since 2009 and member of the Ministerial Advisory Council on the Federal Initiative to Address HIV/AIDS in Canada since September 2003.
Mark Ragan
Mark Ragan (1966-2010) will be dearly missed by all members of the OHTN staff. Mark contributed to the OHTN as an active member of the senior management team for two years, from 2008 to 2010. During this time, he excelled and established himself as a leader in the organization. Initially hired as Manager of the Knowledge Translation and Exchange program, he was soon promoted to Director of Operations and Administration in recognition of his talents in organizational issues and management. Mark was always one of the first in the office and the last to leave, and was instrumental in supporting all of the important work in which the OHTN engages. Mark held a high bar for excellence and innovation, and expected this from himself, and all members of his team and the OHTN staff. He was very adept at managing but also was a big picture thinker and saw what directions the OHTN needed to take to fulfill its mission and make a difference. The OHTN is deeply saddened by his passing, but will remember fondly his positive, optimistic and effective leadership style, and his spirit will continue to enrich the work of the OHTN.

Sergio Rueda
Sergio Rueda
Sergio Rueda is Associate Scientist and Director of Population Health at the Ontario HIV Treatment Network. In this role, he is providing leadership to ensure the OHTN meets its goals of supporting policy-relevant population health research and related knowledge translation strategies within the social determinants of health framework. Sergio is leading the development of a population health research program that situates labour force participation, working conditions and income security as fundamental determinants of health. This program of research uses a variety of methodologies to study the health effects of employment transitions, including longitudinal cohort studies, secondary analyses of existing datasets, and systematic reviews.


More than 50% of the OHTN Cohort Study Governance Committee is made up of people living with HIV.
