As an accomplished physician-scientist specializing in infectious diseases, I bring extensive expertise in clinical trials, communicable disease surveillance, and public health emergencies. I hold an MD from the Federal University of Bahia and a PhD from São Paulo University. My career is marked by significant contributions to the epidemiology and vaccinology in tuberculosis, arboviruses, and COVID-19.

I am an Associate Professor at the Federal University of Mato Grosso do Sul and Yale School of Public Health. Additionally, I am a Researcher at the Oswaldo Cruz Foundation, Mato Grosso do Sul. I have held numerous leadership positions, including President of Rede-TB, President of the Brazilian Society of Tropical Medicine, and Director of the Department of Immunizations and Communicable Diseases at the Ministry of Health.

With over five years of experience in leading vaccine trials, I have been involved in clinical studies for vaccines targeting COVID-19, dengue, tuberculosis, and chikungunya. My research is funded by NIH and Brazilian agencies such as CNPq and CAPES. I have published extensively in high-impact journals and participate in several technical advisory boards, including the Technical Advisory Chamber for Public Health Emergencies, the Technical Advisory Chamber for Surveillance, Prevention, and Control of Respiratory Viruses, and the Technical Advisory Chamber for Immunizations at the Ministry of Health of Brazil.

My work is characterized by a comprehensive approach that combines epidemiology, clinical trials, and programmatic data analysis. I am committed to scientific dissemination and actively participate in initiatives to provide innovation and accurate public health information to the public.
