Dr. Celum's research currently focuses on clinical trials of biomedical HIV prevention and combination HIV prevention strategies with the objective to find effective strategies to reduce HIV acquisition and transmission.
Dr. Celum's recently completed international, multi-center HIV prevention trials include genital herpes suppression for prevention of HIV acquisition among heterosexual women in Africa and men who have sex with men in the Americas (HPTN 039) and among HIV infected persons in African serodiscordant couples to reduce HIV transmission and disease progression (Partners in Prevention).
Dr. Celum is the Principal Investigator of a phase 3 randomized, placebo-controlled trial of pre-exposure antiretroviral prophylaxis, of oral tenofovir and Truvada for prevention of HIV acquisition in serodiscordant couples in Kenya and Uganda. She is a co-investigator in the NIH-funded Microbicides Trials Network. Dr. Celum is PI of a NIH grant on combination HIV prevention strategies for the heterosexual HIV epidemic in Africa. Most of her research is conducted through international collaborations, including with colleagues and sites in Peru, Kenya, and Uganda. She has many collaborators; among them, Drs. McElrath, Marrazzo, Corey, Wald, Lingappa, Baeten and Holmes.
