About me

I am currently in the Department of Computer Science and Engineering at the University of California at San Diego where I work in the Security and Cryptography Group under Professor Mihir Bellare.

Before coming to UCSD, I obtained my Master's degree in Electrical Engineering and my Bachelor's degree in Communication Networks Engineering from the University of Brasília (UnB), Brazil. My advisor was Professor Anderson C. A. Nascimento.

Program Committee Member: WISA 2012, ICISC 2012

Reviewer: STOC 2011, The Computer Journal, ICITS 2012, SBSEG (2009, 2012)
