I am an archaeologist working on Amazonian indigenous archaeology. My research area is southwestern Amazon during Middle and Late Holocene periods, and I am specialized in archaeobotany - macro remains (seeds and fruits) e micro remains (starch grains). I have experience working on shellmounds, geoglyphs and open air sites with Amazonian Dark Earths. I also work with indigenous groups and their plant biotechnology and food production systems at the Purus river.
