After studying patterns of birds community richness across the Tropical region, my current research interests fall within the realm of studies on the evolution of social mating systems, followed by key evolutionary processes shaping biodiversity: positive interactions and sexual selection.
What is the evolutionary causation of social bonds among species and within individuals?
But why should this strategy re-evolve in a manakin species, if polygamy is so successful?

A retrospective of 2018
2018 was a year of great accomplishments and opportunities for the #HelmetedManakinProject and for myself, as a PhD candidate in the University of Brasília. Here I try to list them.
Here it comes the... rain!
Rainy season finally started, and we found around 50 nests!
The Helmeted Manakin Project at full speed!
Total count: 38 individuals of the Helmeted Manakin! And many other cool birds captured on the mist nets.

Since the early ages, I had a singular curiosity on birds. Not a conscious one: somehow, I wanted to understand their language.
A kid develops many other interests, so I have adventured myself through many paths. However, I always kept an eye on networks and natural history, especially of birds.
Today, I am an environmental consultant and PhD candidate at the University of Brasilia (BRA), under the supervision of Dr. Regina Macedo at the dynamic Lab of Animal Behavior. I am excited to dive in the incredible universe of animal behavior, and investigate the mechanisms driving the evolution of species.
I am also very interested in social networks, and the evolution of sociality; natural and anthropogenic processes driving diversity and biogeographic patterns. I am an admirer of A. R. Wallace's studies, and I am fascinated about culture - an enthusiastic violinist and cinephile.
