Currently, I am an adjunct professor in the Department of Physics at PUC-Rio. My research activities focus on Scientific Instrumentation with emphasis on: Scanning Magnetic Microscopy; magnetometry at room and low temperatures; Fabrication of magnetic nanoparticles and construction of theoretical models. All these areas aim at the development and improvement of instruments for measuring magnetic fields generated by a variety of materials such as: magnetic nanoparticles linked to biological agents; Magnetic minerals present in terrestrial and extraterrestrial rocks; Steel components containing fissures and corrosion that are part of the infrastructure of various industries. I have also worked on the construction of magnetic scanning microscopes based on magnetic tunnel junction (TMR) sensors and on the construction of Hall effect magnetometers operating at low temperatures, as well as on the development of control programs using LabVIEW and MATLAB languages.
