Sc.D. from Federal University of São Paulo, PhD from the University of São Paulo (1994), was ryugasei during the doctor course at Nara University of Education and Visitante Professor at Paris Lodron University of Salzburg (2024). She is currently a research professor at the Federal University of Sao Paulo, Santos. Initiated the research area in Optically Stimulated Luminescence (OSL) in Brazil, in 1995, dating sediments from Amazon river and its tributaries. She has experience in OSL and thermoluminescence (TL) of crystals applied to geochronology and environmental dosimetry. The research main lines are: 1) Interdisciplinary studies with geoscientists in the field of paleoenvironmental changes that occur during the Quaternary 2) improving the methodology of dating (marine terraces, aeolian, colluvium, fluvial sediments, archeological soil, etc ... by luminescence of crystals, 3) Implementation of a single grains dating methodology 4) studies of point defects and their kinetics in the luminescence emission and 5) synthesis and morphological characterization and luminescence of crystalline ceramic composites nanoestuturados for dosimetry of ionizing radiation. Member of the Condensed Matter Advisory Board of Cambridge Publisher Scholars Publishing and coordinates Fapesp Themed Project (2024-2029) in the area of #8203;#8203;Geochronology by applying OSL and TL dating.

Studies on the Quaternary fluvial dynamics in the Rio Negro Basin are still scarce, despite this river harboring the two largest fluvial archipelagos in the world, the Anavilhanas and the Mariuá. The Mariuá archipelago has few studies and keeps records of the main sedimentary, climatic and tectonic processes, which influenced the evolution history of this river in the last thousands of ye…

The present project intends to study the Mariuá Archipelago, considered the largest on the planet, which is located in the middle stretch of the Rio Negro, Amazon. It has more than 1,400 islands, whose deposits can keep records of the main sedimentary, climatic and tectonic processes that influenced the evolution stages of the Rio Negro Basin. This archipelago is considered a priority reg…

This project aims to date and characterize the chemical and mineralogical composition of 120 samples of the ceramic artifacts of two pre-colonial archaeological sites: Santa Paula and Teotônio, located in the Teotônio Waterfall, southwest of the Amazon. The approach will be through four analytical methods: activation analysis with instrumental neutrons (INAA), X-ray (XRD), thermoluminesce…
Pure lead borate vitreous matrices and doped with silver will be sintered, aiming at their application in the dosimetry of ionizing radiation. After the synthesis, the samples will be characterized with several techniques: the morphological characterization will be done with SEM to determine the size of nanoparticles or silver agglomerates, EDS to verify if there are impurities originatin…
The present work aims to study quartz crystals taken from sediments of the Archipelago of Mariuá, AM, using the techniques of XRD and TL. The results will be correlated with studies of geochronology and sediment provenance. For this, around 20 samples will be collected from river terraces of the middle Rio Negro, which covers the archipelago, as well as sediments from aeolian dunes found …
Thermoluminescence (TL) ionizing radiation dosimetry has been used since 1940 due to the pioneering study of Garlick & Gibson (1948). Since then, research has been carried out in the area, and currently researchers suggest the use Optically Stimulated Luminescence (OSL) of Alumina for dosimetry. The relevance of this branch is because detector materials are used to monitor doses received …
The luminescent signal of pure and silver-doped sodium borate glass matrices will be studied, aiming for its application in the dosimetry of ionizing radiation. Furthermore, the investigation of the formation of nanostructures in the matrix will be carried out using different heat treatment protocols, varying time and duration. The study of its luminescent response in relation to dose wil…
Ionizing radiation dosimetry by Thermoluminescence (TL) has been used since 1940, and currently, researchers suggest the use of Optically Stimulated Luminescence (OSL). Luminescent dosimeters are used to monitor doses received by laborers working in environments equipped with sources/devices that emit radiation, in addition to patients. Thus, such monitoring is essential to ensure people'…
