Research Focus

My Global Implementation Research program is focused on point-of-care diagnostics for HIV and associated co-infections (hepatitis C, hepatitis B, HPV, bacterial STIs) and COVID-19. My research aims to inform domestic and global policies on point-of-care diagnostics for HIV/STBBI, particularly as it relates to digital health innovations that expand access, linkage and retention, as well as managing the trajectory of care for patients living with these conditions. My work has been featured in the Changemakers section of the Economist twice and in Maclean’s, The Globe and Mail, Montreal Gazette, Times Now, Times, CTV, CBC, La Presse, Radio Canada, BBC and Al Jazeera, among other media. I was featured in the list of Canadian Women in Global Health in 2018 and in 2020. Working in the field of diagnostics for the past 15 years, I have experience with research initiatives in four countries and health systems: the United States, Canada, South Africa and India.
