Postdoc at the International Center for Theoretical Physics – Trieste, Italy (1992) and at the Center for Lasers and Applications at IPEN / CNEN-SP (1992-1995). She has been a full researcher at the Nuclear and Energy Research Institute of the Nuclear Energy National Commission (CNEN) since 1995, where she was Manager of the Lasers and Applications Center in 2008. From 2009 to 2013 she was the Coordinator of the Professional Master Program in Lasers in Dentistry at IPEN, together with School of Dentistry- University of Sao Paulo (USP). From 2013 to 2015 she was Vice-Coordinator of the Master’s and Doctorate Program in Nuclear Technology at USP. She was principal investigatior in a number of FAPESP (CEPID Optics and Photonics) and other National projects (CNPq INCT Photonics) a member of the Medical Physics Commission of the Brazilian Society of Physics from 2008-2014. She was Vice President of the Brazilian Association of Lasers in Dentistry (ABLO) 2010-2014. Participated in the Capes-CA Engineering II Quadrennial Evaluation Committee 2013-2016. She was the creator and since 2019 is the Dean of the Professional Master Course in Radiation Technology in Health Sciences, IPEN. Since 2017, she has been appointed OSA Traveling Lecturer, a member of Education Commission from CNEN. Member of the Deliberative Council of the Brazilian Photonics Society (2021-current) and its Newsletter editor for Biophotonics (2018-2019). During 2019 she was member of the Techinical Group 9 of the Brazilian Committee for the Development of Nuclear Program. Since 2020 is member of the Committee of Photonics – Ministry of Science, Technology and Innovation (MCTI), and Brazilian representative for the IAEA Arcal RL 069 project, on training human resources in the nuclear area. Work in the following fields: Physics, Biophotonics, in the study of Optical and Spectroscopic Properties of biological tissues mainly by micro-FTIR and fluorescence, infrared thermography, aiming at the development of new diagnostic and therapeutic processes for clinical applications of lasers in dentistry and medicine. She has been dedicated to the search for biomarkers to determine the effects of ionizing radiation on biological tissues as well as to study the early diagnosis of skin and breast tumors by vibrational spectroscopy (FTIR optical biopsy).

Title: Analysis of acid resistance of enamel treated with Nd:YAG laser and fluoride in different pHs

High power lasers can be used in caries prevention to increase resistance to demineralization of tooth structure through changes in microstructure.
This study was designed to evaluate the preventive effect of treatment with Nd:YAG laser and fluoride on dental caries by analyzing the acid resistance of treated enamel subjected to different pH conditions.
