Melicent Peck is a board-certified infectious diseases physician. She completed her MD/PhD training and internal medicine residency at Stanford University, infectious diseases fellowship at UCSF, and the Advanced Training in Clinical Trials certificate at UCSF. Her fellowship research focused on HIV immunopathogenesis, specifically targeting extreme phenotypes in HIV infection with a goal to develop novel approaches to HIV cure. She is currently involved in the clinical development of novel antibacterial and antiviral therapeutics. She is an attending physician at the UCSF Infectious Diseases Clinic. I am interested in HIV/AIDS research with particular interest in HIV immunopathogenesis and the development of novel therapeutics that target HIV and chronic immune activation. I have a long-standing interest in host-pathogen interactions, and I am currently studying the immunophenotypic characteristics of viremic non-progressors, a rare group of ART-naïve HIV-infected individuals that maintain normal CD4+ T cell counts in the presence of high-level viremia.
