Biography

Dr. Freitas graduated from UFMG, Brazil and holds a Bachelor’s degree in Physics and PhD in Materials Science Engineering. He has extensive experience with Electron Microscopy (TEM, STEM, SEM, EDS, EELS, EFTEM, Electron Diffraction). Dr. Freitas worked for the multiuser UFMG Center of Microscopy for 12+ years (2009-2021) with the day-to-day operation of the TEM and managed the TEM lab for 4 years (2017-2021).
Dr. Freitas joined Michigan Tech in January 2022 and manages the Electron Microscopy Core Lab at the Materials Characterization Fabrication Facility (MCFF), and teaches the SEM course (MSE4500) and TEM lab sessions of the TEM course (MSE5550).
