Lab Leadership

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

Professor | Simon Lab
Director | Personalized Virology Initiative

Dr. Viviana Simon’s research focuses on understanding viral-host interactions in the context of human and viral diversity. She is 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, she studies 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. Her research has been continuously funded by NIH/NIAID since 2003. In addition to conducting basic research, she serves the community by mentoring and teaching. Not only is she a member of the M.D./Ph.D. Admissions committee, but she is also Director of the Global Health and Emerging Pathogens Institute Seminar Series and since 2016, the Director of the Personalized Virology Initiative.
