Cohn received her Ph.D. from Rockefeller University. As a student in Michel Nussenzweig’s laboratory, she used single-cell strategies to investigate latent viral infection in HIV-1 infected individuals. This research revealed important insights into the mechanisms of viral persistence and maintenance of the HIV-1 latent reservoir. As a Biohub Fellow, Cohn continued these studies by using novel strategies to investigate latent viral infection. She focused on understanding the contribution of tissue-resident cells to viral persistence, developing new isolation techniques to study rare latently infected cells, and elucidated how the virus and host cellular environment work together to maintain latency.
