About me

I began my graduate studies at the Federal University of Paraíba, Brazil, where I completed both a Master's (2011) and a Ph.D. (2014) in Physics. In 2018, I completed a postdoctoral position at the State University of New York (USA). My research has primarily focused on mechanical wave propagation in granular crystals. Since 2014, I have been a professor at the Federal University of Pará (UFPA), Brazil. In 2023, I took part in the foundation of the Physics Faculty at UFPA, Tucuruí Campus, an initiative that has strengthened physics education and research in the Brazilian Amazon region. Currently, I am visiting Graz University of Technology (Austria) as a postdoctoral researcher.

Research Focus

My research at TU Graz focuses on the simulation of multiphase flow systems involving air–dust–grain–droplet interactions, using open-source software (LIGGGHTS and OpenFOAM). In many granular material handling scenarios, dust is generated during processes such as transportation and storage. This issue presents significant environmental, health, and economic challenges. Relevant applications include the mining industry and the recycling of electric vehicle batteries. Dust is released from granular materials during collisions and interactions with air, and its dispersion can be mitigated by controlling the moisture content through spray application.
