Academic mobility has been a relevant phenomenon in Brazil, influencing the trajectory and scientific productivity of researchers. This study analyzes the relationship between academic mobility and scientific production of Brazilian PhDs, using data from the Lattes Platform processed by the LattesDataXplorer framework. The methodology involved the extraction and analysis of 381,462 CVs of PhDs, considering three groups: those who did not migrate, those who migrated nationally, and those who had international mobility. Publications in conference proceedings and journals classified by Qualis CAPES (2017-2020) were examined. The results indicate that academic migration positively impacts scientific productivity. The median number of publications in conference proceedings increased after migration, with a higher volume among those who migrated within Brazil. In journals, most publications are concentrated in higher strata of Qualis (A1 and A2), being more expressive among PhDs with international experience. It is concluded that academic mobility favors collaboration and research impact, but it is not the only determining factor of productivity. Mobility incentives, especially at the national level, can strengthen scientific networks and contribute to research excellence in Brazil.
