About

Hello and welcome to my home page. I am currently a PhD student at the Graduate Program in Computer Science from the Federal University of Minas Gerais. My advisor is Prof. Jussara Marques de Almeida.

My research interests are:

  • Social media
  • Online user behavior
  • Data mining
  • Information retrieval

In the past I have worked with:

  • Grid computing (Ourgrid)
  • P2P computing
  • Business driven IT management

These previous projects were mostly done at the Federal University of Campina Grande, where I did my BSc in Computer Science, and was a member of the Distributed Systems Laboratory.

Around the web you can find me on Github.
