About & Research Focus

I am a Professor in the Department of Technology in Civil Engineering, Computing, Automation, Telematics, and Humanities (DTECH) at the Universidade Federal de SĆ£o JoĆ£o del-Rei (UFSJ), Campus Alto Paraopeba (CAP).

I hold a Ph.D. in Electrical Engineering from the Universidade Federal de Minas Gerais (UFMG) with research conducted in collaboration with Technische UniversitƤt Dresden (TU Dresden), focusing on Information Theory applied to spoken communication. My research and teaching span Information Theory, Digital Signal and Speech Processing, Multiresolution Wavelet Filter Banks, Data & Multimedia Compression, and the development of Open Source Tools and Scientific Educational Resources.

I also serve as Section Editor and Layout Editor for Texto Livre (UFMG, Qualis CAPES A1), an open-access journal focused on language, technology, and free culture.
