I hold a Ph.D. in Ecology from the Federal University of Juiz de Fora, Brazil, and currently serve as a postdoctoral researcher at the Ecology department of Radboud University. My academic and professional background centers around Limnology, aquatic and sedimentary biogeochemistry, greenhouse gas emissions, climate change effects, and environmental impact assessments. My expertise extends to applied science, where I explore scientific tools geared towards mitigating anthropogenic impacts on freshwater environments. I am particularly passionate about efforts aimed at reducing greenhouse gas emissions originating from aquatic environments and sludge depots and enhancing carbon storage in lakes. My work reflects a commitment to the practical application of scientific knowledge to address contemporary environmental challenges, with a specific focus on the sustainable management of aquatic ecosystems.

Projecten

2021 - 2025 “Decreasing greenhouse gas emissions from surface waters by climate-smart water management (DIGS)” In this project, we aim to quantify greenhouse gas (GHG) emissions and carbon burial in different types of shallow inland waters in the Netherlands. In addition, we will also identify the environmental drivers responsible for these emissions and carbon storage in order to produce (heat) maps with national greenhouse gas emissions. These pieces of knowledge will be further used to develop robust mitigation strategies to reduce GHG emissions and maximize carbon storage in aquatic environments. My role in the project is mainly related to fieldwork activities and laboratory experiments related to the production and emission of CO2, CH4, and N2O, as well as processes linked to carbon burial in the sediments of these aquatic environments.
2014 - 2020 "Towards a new understanding of carbon processing in freshwaters: methane emission hot spots and carbon burial in tropical reservoirs (HYDROCARB)" HYDROCARB investigates the carbon and greenhouse gas balance of tropical hydropower reservoirs. Financed through the European Research Council (2014-2020), it is a joint research project of Limnology program at Uppsala Univeristy (SWE) and the Aquatic Ecology Laboratory at the Federal University of Juiz de Fora (BRA). Even though the financing period has ended, the team is still active and productive. HYDROCARB creates new understanding of reservoir carbon cycling by studying 1) CO2 and CH4 emission at high spatial resolution, and across temporal scales. Carbon burial in reservoir sediments 2) The sources of organic matter that fuel CH4 production in sediments. The aim is to establish new carbon and greenhouse gas budgets of tropical reservoirs, and to make the new knowledge available to both scientists and stakeholders. Meer informatie
2022 - 2023 "Quantification and mitigation of GHG emissions from dredged sediments: from in situ assessments to laboratory assays" In this project, we intend to quantify CO2, CH4, and N2O emissions from sediments (also known as sludge) dredged from agricultural ditches in the southeast of the Netherlands, which were left to dry under atmospheric conditions. The project consists of the in-situ monitoring of these climatically-important gases, as well as other environmental variables, throughout the entire cycle of drying. In addition, we investigate the role of environmental events (eg emergence of vegetation over the drying sludge and periods of rain) on GHG dynamics. Ultimately, we also study techniques that can mitigate GHG emissions from outdoor drying sludge (such as the addition of chemicals and keeping the sludge inundated) in order to reduce the climate impacts of dredging.
