Research Project: Andes and 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 the biggest water supply system in the state of São Paulo, Brazil.

 I am a Postdoctoral researcher at Florida Institute of Technology and my main research interest is to investigate the response of tropical ecosystems to different forcings over time.  On my Ph.D. at Florida Institute of Technology my primary objective was to understand how Andean and Amazonian ecosystems changed in response to the Holocene droughts and to the increase in the use of plant cultivation and animal domestication by humans in South America. To evaluate such dynamics, I used diatom, pollen, Sporormiella, charcoal, loss-on-ignition and X-ray fluorescence (XRF) analysis as proxies to past changes in the landscapes. 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 in the Peruvian altiplano. As a Ph.D. student I was successful on the acquisition of the National Geographic Society Waitt Grant, which paid for an expedition to the Hill of Six Lakes, in the Brazilian Amazon basin. As the leader of this expedition, I worked for two years to obtain the permits from the Brazilian government and local indigenous communities to work on their territories. During this campaign, I raised cores from lakes that had never been previously visited by scientists. Besides Hill of Six Lakes, I participated in field campaigns in different tropical high and lowland regions (Brazil, Peru, Ecuador).
