Saulo Ribeiro de Freitas is a physicist who graduated from the Federal University of Goiás (1987) with a master's degree from the Federal University of Pernambuco (1991) and a Ph.D. from the University of São Paulo (1999). He is a Senior Researcher and Professor of Meteorology at INPE, where he leads the Division of Numerical Modeling of the Earth System. Previously, he was a Senior Researcher at NASA Goddard Space Flight Center (USA) from 2016 to 2021. He has extensive international experience, including a postdoctoral fellowship at NASA Ames Research Center (USA, 2000/2001), and programs such as Young Researcher at FAPESP (2001-2003). His research interests include atmospheric chemistry, atmospheric dynamics, numerical modeling, and weather prediction integrated with chemistry and aerosols. He is one of the main developers of the regional modeling system BRAMS and coordinated the development of operational prediction systems at CPTEC/INPE. He is the author or co-author of 138 articles in indexed journals, actively participated in international research groups, and held leadership positions at CPTEC/INPE.
