Postdoctoral researcher at Universidade Federal Fluminense (Brazil), with a project granted by the state research foundation (FAPERJ). I am studing the nutrient and As behaviors in tidal creeks in mangrove from southeast Brazil. After almost 20 years after undergraduation, I turned to research area and I really enjoy doing it. I (re)started with a master's degree in 2016 and in these 9 years I have contributed to the application of geochemistry in reducing environmental impacts in coastal areas.
