I have a PhD degree in sustainability at the University of Sao Paulo (USP, Brazil), with part of the doctoral research carried out in Kartik Chandran's lab at Columbia University. I have a bachelor's and master's in the environmental field in with research exchange at Blanca Jimenez's group at the National Autonomous University of Mexico. For the last 10 years, I have been working in research projects for the development of environmental science and technology, biotechnology and sustainability.

Treatment of landfill leachate is a challenge due to its complex chemical composition and high recalcitrance and because of high costs for conventional wastewater treatment. In our study, leachate from the Quitaúna Landfill, Sao Paulo Metropolitan Region, Brazil, was treated at a laboratory scale with a horizontal subsurface flow constructed treatm...
One of the key challenges in landfill leachate treatment is removing organic matter (OM) and ammonium nitrogen (NH4 +-N) at a low cost. To evaluate the feasibility of treatment wetlands for diluted (3:10) landfill leachate treatment with OM and NH4 +-N oxidation, a lab-scale shallow subsurface horizontal flow system (HF wetland) comprised of two un...
Microbial fuel cells (MFC) generate clean energy from organic wastes. This study reports the development and application of novel lab-scale MFC with granular activated carbon-modified electrode fed with synthetic sug-arcane vinasse. Biological activity involving nitrogen in the cathode chamber was assessed as a strategy to improve cathode performan...

Industrial development and high urbanization are responsible for several environmental problems, as the effluents generated cause disturbances to the ecosystems and risks to people's health due to the release of pollutants that are not properly treated. Based on the nature of wastewater, quantitative and qualitative aspects, different types of tech...
The microbial fuel cell (MFC) is a novel technology that can generate clean energy from wastes. In this study, a novel double chamber MFC with low-cost electrodes was developed and assessed to convert organic matter into electricity under different temperatures (~25, 35 and 55 °C), external resistances (13 and 300 Ω) and electron acceptors (oxygen...
The deficit in environmental sanitation and the increasing demand for electricity is increasing the need to invest in both sectors. In this sense, the Microbial Fuel Cell (MFC) is presented as a promising technology to be employed in the treatment of wastewater, protecting the quality of surface and groundwater while simultaneously generating renew...
Sistemas de tratamento de esgotos, quando aplicados ao tratamento de lixiviado de aterro sanitário, não têm apresentado bons resultados. Por conta disso, faz-se necessário o desenvolvimento de alternativas para o tratamento de lixiviado. Assim, buscou-se avaliar o pós-tratamento de lixiviado de aterro sanitário por wetland construído de fluxo subsu...
A falta de redes coletoras e de estações de tratamento esgoto é um grande problema vigente em países emergentes que ainda tende a ser justificada pelo alto custo embutido nas obras de instalação e implantação das plantas de tratamento. Desta forma, este trabalho teve com objetivo avaliar comparativamente a eficiência de remoção de matéria orgânica...
A degradação de corpos d’água por despejos de esgoto bruto é um problema recorrente principalmente em países emergentes. A busca por métodos e tecnologias de tratamento que promovam o aproveitamento dos nutrientes contidos no esgoto e o reuso da água se colocam neste contexto como alternativas para a promoção da sustentabilidade e conservação das á...
O presente estudo teve por objetivo avaliar a eficiência de remoção de poluentes de esgoto doméstico através de wetlands construídos. O sistema foi implantado na Escola de Artes, Ciências e Humanidades da USP e operado em duas fases. A fase 1 foi caracterizada pela operação de unidades em escala piloto-real, pelo pós-tratamento do efluente de um Re...
This study aimed to implement and monitor 03 units of sewage treatment by constructed wetlands systems in the post-treatment of a UASB reactor. The deployment of the units occurred in the Sewage Treatment Station of School of Arts, Sciences and Humanities of University of São Paulo - EACH / USP, São Paulo, between September-October 2010. For system...
When using microbial fuel cell (two chambers), with oxidation of organic matter in the anode chamber and transportation of electrons to a cathodic electrode with DO absence and the presence of nitrate in the cathodic chamber.
Considering the absence of readily biodegradable organic matter in the cathode chamber.
