Lab Leadership

Viviana Simon, M.D., Ph.D.

Professor | Simon Lab
Director | Personalized Virology Initiative

My research focuses on understanding viral-host interactions in the context of human and viral diversity. We are interested in the mode of action of known (APOBEC3 cytidine deaminases, SAMHD1) and novel retroviral restriction factors as well as the corresponding HIV, SIV and HTLV antagonists. In addition, we study the mechanisms driving HIV-1 drug resistance, the role of copy number variation within immune system genes and develop tools to study HIV latency and anti-sense transcription at the single cell level. My research has been continuously funded by NIH/NIAID since 2003. In addition to conducting basic research, I serve my community by mentoring and teaching. I am the Co-director of the Advanced Virology Class and I am active in the Microbiology graduate training area (M.D./Ph.D. Admissions committee) and in the Global Health and Emerging Pathogens Institute (Director of the Global Health and Emerging Pathogens Institute Seminar Series).
