Ph.D. in Materials Science and Engineering (2019) and Materials Science and Engineering (2015) - University of São Paulo (USP), São Carlos, Brazil.
2012 - Bachelor in Physics - São Paulo State University (UNESP), Rio Claro, Brazil.

Research areas

    • Femtosecond laser micromachining
    • Nonlinear optics
    • Special glasses

Her research is in the areas of optics and photonics applied to materials. Her research interests include the study of optical nonlinearities and femtosecond laser microfabrication in special glasses. In her doctorate supervised by Prof. Dr. Cleber R Mendonça, the interest was to investigate third-order nonlinearities and the production of optical waveguides in borate glasses that are little explored as a nonlinear optical material. In addition, the influence of rare earth ions on the third-order nonlinear optical response and also on the results obtained from waveguides coupled with different wavelengths was analyzed.
