Currently, I am a Ph.D. Candidate with the University of São Paulo, where I am advised by Professor Anna Reali Costa. During the last year, I was a Visiting Researcher at the University of Texas at Austin, where I worked with Professor Peter Stone on my main Ph.D. research topic.
My main current research topic is Transfer Learning for Multiagent Reinforcement Learning (read more about it in my survey here, or in its shorter version here). I received the M.S. degree in Electrical Engineering from the University of São Paulo in 2015 and the B.S. degree in Computer Science from the Pontifical Catholic University of São Paulo in 2012.
Transfer Learning in Multiagent Reinforcement Learning Systems
Reinforcement Learning is a powerful and autonomous tool to train intelligent agents.
This learning is initially performed by successive interactions between agents and the environment in a trial and error manner until the agent has enough information to perform its tasks.
However, when multiple agents are present in the same environment some sort of coordination is required since the environment becomes non-stationary. Centralized approaches are usually infeasible, as the state space can be huge even for simple problems.
Thus, distributed approaches are required for many Multiagent domains.
This research aims to develop a framework to accelerate learning in Multiagent Reinforcement Learning Systems by applying Transfer Learning, which has been successfully applied in Single Agent domains but has no robust algorithm to complex Multiagent domains.
Automated Bee Species Identification through Wing Images
Bees have a huge importance to pollination, which motivated research focused on their conservation.
However, some bee species are so similar that only a few specialized taxonomists are able to make a proper discrimination.
This project studied computer vision and machine learning methods applied to bee wing images to discriminate bee species.
I'm not working on this project as a first author anymore, but I've been advising undergraduate research projects on this topic.

Music I've been playing electric guitar since I was 15 years old. Even though I'm far from claiming to be in a professional level, you can count on me if you want to have fun playing some old good heavy metal.
Horror Movies I was just a little boy when I first watched "Night of the living dead". Thereafter I cannot spend a week without watching a B movie (specially the brain-eater zombie ones).
