Behavioural Informatics Group

I'm currently working together with researchers from the Behavioural Informatics Group, a research group from Vrije Universiteit Amsterdam (VU), while developing my PhD thesis. This group focus on using Computer Science to understand (and provide improvements for) human processes. Mainly, I'm doing research about people coping with stress together on social networks and the role that artifical friends could play within this type of scenario. This will be the topic of my thesis.


IMPACT stands for Impact of Cultural Aspects in the Management of Emergencies in Public Transport. In this project, funded by the EU, we used dynamic computational models to investigate the essential role played by cultural factors in managing safety and security issues related to emergencies in public transport systems.

VU Amsterdam & RU Nijmegen

Since August 2015 I am a PhD candidade in Computer Science at VU*. From February 2018 I started to be considered as a PhD student at RU* as well, after a joint doctorate supervision agreement between both universities. I'm planning to defend my PhD thesis until the summer of 2019 and my supervisors are Prof. Dr. Jan Treur and Prof. Dr. Tibor Bosse.

Federal University of Campina Grande

I received my titles of B.Sc. and M.Sc. in Computer Science from the Federal University of Campina Grande in 2012 and 2015, respectively. During my Master's degree studies, I was supervised by Dr. Nazareno Andrade and my thesis was evaluated by him, D.Sc. Carla Berkenbrock and Dr. João Brunet.

Distributed Systems Lab

During my Master's degree studies, I was a member of the Distributed Systems Lab from the Department of Computer Science at the Federal University of Campina Grande. Using the infrastructure of this lab, I performed all the experiments that gave me the data I used for writing my thesis. Such a work is about Computer Supported Cooperative Work (CSCW) and addresses the use of social networks in social Q&A sites.

E.life Group

From October 2013 until November 2014 I worked as software engineer at the E.life Group. I collaborated with the development of the Buzzmonitor - a web-based low cost software to collect and classify data from social media and to interact with users. In this job I could work in a project using big data from social networks by developing a system on the cloud with lots of functionalities for so many different clients around the world. During this experience I realized that would be great to work with social networks and artificial intelligence.

Campina Tec

During my work at Campina Tec, from October 2011 until July 2012, I worked as software engineer in the development of web-based softwares on demand that aim to improve industrial automation by managing sales and production. During this job I put my hands on systems using huge databases. Besides that I could learn how to better argue with real clients.

Department of Technology at Ministério Público da Paraíba

In 2011, from March to October, I worked as an intern at MPPB (Paraíba state's public agency for law enforcement). I paticipated in the development of a web-based low cost software that aims to help prosecutors from the city of Campina Grande in managing cases of unknown paternity via CRUD of these lawsuits on cloud. Since it was my first job experience, everything I did there was really important to show me how things happen in a real work environment.

Research focus

My current research is in the line of human-aware agents supporting people, often dealing with their social networks. My research interests are: human-aware computing, ambient intelligence, pervasive computing, ubiquitous computing, social networks, CSCW and computer-human interaction. Here you can briefly check my last publications.
