I am an infectious diseases specialist and an expert in HIV perinatal medicine who has a long-term experience with HIV-infected patients and prevention of mother-to-child transmission (PMTCT) of HIV. Currently I am conducting research on COVID-19 in collaboration with Columbia University and Fred Hutchison/CoVPN. I am a consultant of the Consulting Committee for Antiretroviral Therapy in HIV-infected Pregnant Women of the STD/AIDS National Program of the Brazilian Ministry of Health. I am a member of the IMPAACT HIV Prevention Scientific Committee. I am the Co-Chair of Protocol P1081. I am the head of the HIV perinatal program for Hospital Federal dos Servidores do Estado, a federal reference center for PMTCT in Rio de Janeiro, one of the most important centers of PMTCT in Brazil. Me and my team of investigators have a number of publications in the field, including several collaborative studies with researchers from UCLA, NICHD, Fundação Oswaldo Cruz – FIOCRUZ in Rio de Janeiro, and Federal University of Rio de Janeiro. I am a reviewer of several scientific/medical journals.
