Dr. Marques obtained his Ph.D. in 2002 from the Department of Microbiology at Universidade Federal de Minas Gerais working on the characterization of wild poxviruses. After obtaining his Ph.D. he joined the laboratory of Bryan Williams at the Cleveland Clinic in the state of Ohio, USA in 2002 where he studied nucleic acid sensing mechanisms. In 2006, his interest in the area of RNA interference led him to move on to a new position in the laboratory of Richard Carthew where he developed Drosophila melanogaster models to study antiviral defense. Dr. Marques returned to Brazil in 2010 to join the Department of Biochemistry and Immunology at Universidade Federal de Minas Gerais. He has extensive experience in diverse areas of research such as virology, immunology, bioinformatics and genetics. Since his return, he has dedicated a lot of his time to research on the development of novel approaches to the fight transmission of arboviruses by mosquitoes such as Dengue virus. He has also pursued ways to contribute to the improvement of Brazilian science by getting involved with science policy and public outreach.
