Assistant Professor at the Institute of Geosciences, University of São Paulo (IGc-USP). My research focus lies in the analysis of organic geochemical indicators for paleoenvironmental and paleoclimatic studies, as well as the assessment of changes in the carbon balance in rivers, lakes, and reservoirs.

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…
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…
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…
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…
The Amazon Rainforest and the Amazon River System are unique ecosystems supporting the world´s largest terrestrial and aquatic biodiversity. Those ecosystems also have an important role for the global climate system and precipitation distributionin South America. The Xingu and Tapajós Rivers are the largest clear water tributaries of the Amazon River. Both rivers stand out due to their sp…
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…
