I am a PhD candidate in the Computer Science Division of the University of California, Berkeley. I work with professor Ion Stoica on tracing the execution of widely distributed applications for troubleshooting and performance debugging. I also work on networking problems for wireless sensor networks.

Broadly, I am interested in understanding the behavior of systems with many components for enabling new functionality, and making sure they work as they should. I am also interested in the impact that telecommunications and computing may have on development. I am part of the RADLab, Berkeley's Reliable Adaptive Distributed Systems Laboratory.

I obtained my Master's and B.S. degrees in Computer Science from the Universidade Federal de Minas Gerais, Brazil, working with prof. Virgilio Almeida.

personal

I am originally from the city of Belo Horizonte, Brazil.

I have the most wonderful wife, Paula, the love of my life. We got married in June of 2002, and moved to Berkeley in August of the same year.

I also enjoy playing tennis and photography.
