Juliana Mara Pinto de Almeida

PhD student on Materials Science and Engineering.
Bachelor in Hard Science (emphasis in Physics) and Master in Materials Science and Engineering at University of São Paulo (USP), São Carlos, Brazil.

Research areas

    • Nonlinear optics
    • Glass materials
    • Femtosecond laser micromachining

Juliana has been developing research on nonlinear optical properties of glass materials. The Third-order susceptibility has been determined by Z-scan technique.
Production of metallic nanoparticles and waveguides inside glasses have also been studied.
