My research interests include ore mineralogy, crystallographic texture analysis using EBSD (Electron Backscatter Diffraction), and automated mineralogical characterization using QEMSCAN and MLA. Currently, I am an Assistant Professor at the University of Brasília, where I teach Crystallography at the undergraduate level and Analytical Techniques for Minerals and Rocks at the graduate level in Geology. I also serve as the Extension Coordinator of the Institute of Geosciences, leading outreach initiatives focused on the dissemination and popularization of Science.
In addition, I am currently pursuing an MBA in Green Hydrogen and Energy Transition, and I am involved in projects that promote collaboration between the university and the industrial sector, fostering the integration of scientific knowledge with technological and sustainable development.

FUTURE PROJECTS

Phase transformation processes of iron oxides

I am seeking collaborators for a research project focused on the phase transformation processes of iron oxides. The study aims to investigate the structural, chemical, and textural evolution of iron oxides under varying physicochemical conditions, combining experimental methods with advanced microscopy and mineralogical analysis. The project seeks to better understand transformation pathways between hematite, goethite, and related phases, with implications for mineral exploration, environmental processes, and materials science.
