Dr. Marianne Mureithi serves as the Chair of the Department of Medical Microbiology & Immunology at the Faculty of Health Sciences, University of Nairobi, Kenya, and as Team Leader at the Kenya AIDS Vaccine Initiative - Institute of Clinical Research (KAVI-ICR). She is also a co-investigator in the ADVANCE program under the International AIDS Vaccine Initiative (IAVI). Her educational background includes degrees from the University of Essex and the University of Bristol, as well as a post-doctoral fellowship from the Ragon Institute of MGH, MIT, and Harvard, USA, and the University of KwaZulu-Natal, SA. Driven by the dream of a world without AIDS, Her research focuses on characterizing the early stages of HIV infection, studying the phenotype of target cells in mucosal tissues, and investigating the establishment of mucosal viral reservoirs, particularly in the female genital tract. She also analyzes biological markers and metabolomics in early HIV infection to support vaccine design and treatment development.

Dr. Mureithi is also actively involved as a lead in the Kenya Research and Training Centre's priority area of Strengthening and Increasing Access to a Network of Facilities and Resources. She is also part of the leadership of the Women's Health Project in Mombasa, which is a collaborative initiative between the University of Nairobi and the University of Washington.
