About

I'm a Ph.D student in Computer Science at NYU-Polytechnic School of Engineering. I started my I started my PhD studies at the University of Utah. Due to a group transfer, I moved to NYU in Fall 2011. My advisor is Claudio Silva. My research focuses on Information Visualization, Scientific Visualization. I'm also very interested on Computational Geometry, Computational Topology and Mathematics in general.

About Me

I'm from Recife a beautiful city that is the capital of the state of Pernambuco in Brazil. There I did my high school studies at Centro Federal de Educacao Tecnologica de Pernambuco (now known as Instituto Federal de Pernambuco). During this period I used to participate in mathematics and physics competitions.

I got a Bachelor in Computer Science degree from Universidade Federal de Pernambuco (Federal University of Pernambuco, Brazil). I also got a Master's degree in Mathematics from the same university.

In 2010 I came to USA to start my PhD graduate work in Computer Science at the School of Computing at the University of Utah in the Fall of 2010. In Fall 2011, I transfered to NYU.

Research Interests

My research focuses on Information Visualization, Scientific Visualization. I'm also very interested on Computational Geometry, Computational Topology and Mathematics in general.
