Dr. Cohn performs research in two important and emerging areas of global health: health system strengthening and global health policy, focusing on implementation science and access to medications and the introduction of innovative health products and models of care. Dr. Cohn served as the principal investigator for several multi-national implementation projects with embedded operational research. These projects included a $63 million USD grant from UNITAID rolling out point-of-care early infant diagnostic technologies (POC EID) across 9 countries. She served as the PI on a concomitant randomized stepped-wedge trial documenting the impact of POC EID on EID results being received by caregivers and subsequent antiretroviral therapy initiation in HIV-infected infants. Dr. Cohn was also the co-investigator on a cost-effectiveness project examining POC EID use in sub-Saharan Africa. Dr. Cohn was also the PI on a $38 million USD grant from Unitaid for a ten-country project focused on improving prevention, diagnosis, treatment and care for pediatric TB, including through the introduction of innovative diagnostics and treatment formulations. This project includes two randomized controlled trials, observational cohorts, cost-effectiveness research and qualitative assessments. Although the project and studies are on-going, this work has led to several abstracts and two peer reviewed manuscripts. I am also a co-investigator on several other studies including an CDC-funded observational study looking at the impact of implementation of a comprehensive care program for people living with advanced HIV, and Unitaid-funded study of the uptake and impact of new pediatric anti-retroviral formulations, a CDC-funded study of use of raltegravir granules for neonates in Zimbabwe, and a Bloomberg Philanthropies-funded quasi-experimental study of a public health approach to the provision of hypertension care.
