Universidade de São Paulo (USP). Instituto de Geociências (IGC) (Institutional affiliation from the last research proposal) Birthplace: Brazil
Assistant Professor at the Institute of Geosciences (IGc), University of São Paulo (USP), with a background in Geology, a PhD in Geosciences (Geochemistry and Geotectonics), and postdoctoral training at the School of Arts, Sciences and Humanities (EACH), University of São Paulo. He also carried out a research stay abroad at the University of Bremen (Germany). His research focuses on organic geochemistry, sedimentology, and paleoclimatology, with emphasis on reconstructing paleoenvironmental and paleoclimatic changes in tropical fluvial systems, particularly within the Amazon Basin. He is the principal investigator of FAPESP Project #2022/06440-1, which investigates carbon dynamics and natural CH#8324; emissions in Amazonian wetlands, and he coordinates the Organic Geochemistry Laboratory at IGc-USP (LAGO-USP). He leads and collaborates on national and international multiproxy research projects, supervises undergraduate and graduate students, and serves as a reviewer for international scientific journals.

This proposal aims to strengthen the training of highly qualified professionals to meet national strategic demands in the oil and gas sector, as well as environmental challenges and essential inputs for the energy transition toward a low-carbon economy. It updates the scope of PRH 43.1, Human Resource Training Program in Petroleum Geology, selected under Public Call No. 01/2018/PRH-ANP. T…
The 2.5-fold increase in atmospheric concentrations of methane (CH4) is thought to have been responsible for up to 0.5°C of anthropogenic global warming. In 2007, CH4 concentrations resumed rising at expressive rates after almost a decade of near-zero growth. The mechanisms behind this erratic behavior remain unclear. Still, several lines of evidence suggest that wetland areas, which acco…
Este projeto de treinamento técnico tem como objetivo oferecer uma oportunidade de capacitação de 24 meses para uma bolsista no Laboratório de Geoquímica Orgânica do Instituto de Geociências da Universidade de São Paulo (LAGO-USP). A bolsista participará de atividades voltadas para a extração de lipídios, preparação de amostras e análises por cromatografia gasosa, com ênfase especial no p…
Deciphering hydroclimatic imbalances in the Lower Amazon River Basin is challenging. Speleothem records show a consistent increase in precipitation over western Amazonia from the mid- to late Holocene, but other parts of the basin appear to have responded differently. Previous literature has regarded the contrasting difference in Amazonian precipitation as a dipole response to orbital-sca…
The aim of this project is to investigate the sedimentation of microplastics (MPs) in coastal regions influenced by the Amazon River sediment plume and to analyze the temporal variation in the deposition of these microparticles. Since the onset of mass plastic production in the 20th century, millions of tons of plastic waste have accumulated annually in the oceans, posing significant risk…
Freshwater wetlands are the single largest natural source of methane (CH4) to the atmosphere. Amazonian floodplains alone correspond to roughly one-fourth of global wetland emissions, but its impact to abrupt variations in the global CH4 budget remain under-explored. The abundance and relative concentration of soil-sourced bacteriohopanepolyols (BHPs) in sediment records has been successf…
Archives like marine sediment cores register environmental conditions through proxies in an indirect way. Thus, the appropriate reconstruction of paleoenvironmental changes rely on understanding the relationship between the aimed original environmental signal and the analyzed proxy. Here we will (i) determine how environmental signals are recorded in modern fluvial sediments, and (ii) ass…

Changes in Amazonian hydrology and vegetation have significant impacts on the global geochemical and hydrological cycles. In particular, the vast Amazon floodplains act as major sources of atmospheric methane (CH¿), meaning that changes in their extent can significantly affect the global CH4 budget. This internship proposal aims to analyze two marine sediment cores collected offshore the …
The Amazon Basin, has become an increasingly important focus for paleoclimate reconstructions aimed at improving our understanding of long-term climate variability and its relevance to ongoing climate change. Organic molecular proxies have proven to be valuable tools for retrieving information about past climate oscillations. Among the various terrestrial climate archives, speleothems sta…
Concerns about human-induced climate change have promoted efforts to understand how tropical ecosystems were affected by climate oscillations in the past. To date, a significant part of the available information has been obtained by analyzing organic molecular proxies in marine sediments. An appropriate interpretation of these proxies, however, depends on the understanding of how organic …
The Xingu River is a large clearwater tributary in the eastern Amazon with unique biodiversity and socioeconomic importance. Anthropogenic impacts such as deforestation and hydropower dams building can promote shifts in hydroclimate and sedimentation, affecting ecosystems and carbon cycling. Severe climatic changes are expected to affect the eastern Amazon during the next decades. However…
