I'm a fifth year Ph.D student in Computer Science at University of California, Santa Barbara, and a Research Assistant in the Databases, Data Mining and Bioinformatics Lab, also at UCSB. My current research is focused on dynamic graphs and my advisor is Prof. Ambuj Singh. Before I came to UCSB, I got a B.Sc and an M.Sc degree in Computer Science from Universidade Federal de Minas Gerais, in Brazil. I've also been a visiting scholar at Rensselaer Polytechnic Institute and a research intern at the IBM Thomas J. Watson Research Center and HP Labs. I was the president of the UCSB CS Department Graduate Student Council for 2015, organizing department events including the Graduate Student Workshop on Computing. Here is my CV.
