Currently, I am an associate professor at the Institute of Computing, University of Campinas (UNICAMP) since December, 2009. I received a bachelor's degree in Computer Science from Federal University of Lavras (UFLA) in 2003. I received the Masters degree (2006) and PhD (2009) in Computer Science from the Institute of Computing, University of Campinas. Finally, I worked at the same Institute as a Postdoc fellow until December 2009.

My main research interests include problems related to Digital Forensics, Biometrics, Pattern Analysis and Machine Intelligence and Reasoning for Complex Data.

If you would like to research in one or more of the following topics, please feel free to contact me. Students are more than welcome. Furthermore, if you have one specific topic in mind and want to discuss it, I'm also open to new ideas.
