ML Engineer at GCU: researching skills in Open Source Software, matching knowledge models to improve allocation of professionals to tasks.

DBEM Think Tank collaborator. Using AI for social goodness.

Advisor of the CAIR - Canyon AI Research: CAIR

My PhD under the supervision of Dr. Marco Aurelio Gerosa and Dr Igor Steinmacher at School of Informatics, Computing & Cyber Systems (NAU) from the Northern Arizona University (NAU), addressed skills to solve Open Source Software (OSS) tasks. My project aims to help new contributors to find a new task to start contributions by labeling the tasks with the skills needed to solve them. I am interested in Software Engineering, Open Source Software, AI, Machine Learning and Knowledge Modeling.


My PhD research at Universidade Federal do Estado do Rio de Janeiro (UniRio) under the supervision of Dr. Carlos Eduardo Ribeiro de Mello addressed the matching of knowledge models using networks of ontologies. We created a methodology to match the networks of ontologies without comparing all possible concepts using pattern mining in graphs. My research started under the supervision of Dr. Kate Revoredo and Dr. Fernanda Baião.

I got my Master's degree in Informatics at the Pontifical Catholic University of Rio de Janeiro (PUC-RIO) under the supervision of Dr. Marco A Casanova and Dr. Roberto de Beauclair Seixas. During the Master's I had researched about Mobile Databases. I have designed SAE-WAP a mobile application to assist the management of warfare exercises of the Brazilian Marines.
