I have a Bachelor's Degree in Oceanography from the Federal University of Pará (2013), with a Professional Master's Degree in Sustainable Use of Natural Resources in Tropical Regions by Vale Institute of Technology (2015) and a PhD in Science (2020) from the Center for Nuclear Energy in Agriculture (CENA / USP), with internship (2008) at the University of Sorbonne, France. My areas of expertise are paleobotany and paleoclimatology, with a focus on paleoenvironmental reconstruction studies and paleoclimatic inferences in the Amazon, in which I apply tools such as palynology, charred particles, stable isotopes (C, N) and Carbon-14, as well as stable isotopes of H and C in specific compounds (n-alkanes, fatty acids) preserved in lake sediments to obtain information about paleoprecipitation throughout the Late Quaternary.

After the 1990s, with increasing scientific evidence of widespread human interference in Amazonian landscapes, a new paradigm was developed for the Amazon. Before seen as a pure and untouched ecosystem, the Amazon is now considered to be home to ancient urban processes, cultural activities, among which stand out a long history of domesticating plants in sync with significant changes in th…
The integration of chronological characterization tools as C-14 dating, sedimentologic, conventional and isotopic geochemistry and palynology, is extremely important in studies on the landscape evolution and the dynamic of paleovegetation, with climate inferences. In order to enlighten paleoclimate issues in the Amazon, a sedimentary testimony of ~ 10 m depth will be collected in an activ…
Several previous studies have confirmed the importance of the D/H ratio [deuterium (2H or D) and hydrogen (H)] in compound-specific extracted from lacustrine sediments such as paleohydrological proxies. Innovative analytical methods demonstrated that the hydrogen-isotopic composition of individual lipids from aquatic and terrestrial organisms is strongly correlated with rainwater composit…
