Research Project: Amazon Paleoecology

I got my Bachelors in Biological sciences and education from Universidade Guarulhos, SP, Brazil in 2006. In 2012 I completed my master's degree at Sao Paulo Botanical Institute, using water chemistry and diatom ecology to identify sources of organic pollution in a water supply system in the state of São Paulo, Brazil.

Currently, I am a PhD candidate at Florida Institute of Technology and my research focuses on South American ecology and the vegetation responses to paleoclimate changes. I am trying to understand what the role of Atlantic versus Pacific influences was on the hydrological patterns of tropical South America during the last 12 thousand years, and how they affected the vegetation at different elevations. Another question addressed by my research is how agropastoralism affected the landscape. I use pollen, diatoms, geochemsty and charcoal to understand the changes of the landscape in response to climatic and anthropic forcings. I use pollen to detect changes in vegetation, diatoms and geochemistry to detect hydrological changes, and charcoal to detect fire and human landuse. My study takes place in the Amazon basin and Andean Altiplano and includes the lakes Pata in the Brazilian lowlands, Lake Llaviucu in the Ecuatorian middle elevation forest, and Lake Miski y in the Peruvian altiplano.
