About Me

I am a postdoctoral scholar in Computer Science at the Stanford University, working with Professor Alex Aiken on scalable task-based programming systems.

I received my Ph.D. in Computer Science from the University of Illinois at Urbana-Champaign in 2020, advised by Professors David Padua and William Gropp. During the Ph.D., I developed Locus, a new system, and a language for optimizing complex, long-lived applications for different platforms. It can ameliorate the difficulty of optimizing applications using a methodology based on optimization programming and automated empirical search. The Locus language allows the definition of a search space combined with the programming of optimization sequences separated from the application’s reference code. Based on a Locus program, the system automatically selects, generates, and executes candidate implementations to find the one with the best performance. I was also part of the XPACC project.

During the summer of 2017, I headed off to Seattle, where I joined the Programming Systems and Applications Research Group at Nvidia Research. At Nvidia, I worked on a code optimizer for deep neural networks.

In 2015, I spent the summer at the Lawrence Livermore National Laboratory. My research mostly focused on understanding how to use machine learning to explore the space of code optimizations efficiently.

I have also spent some good years researching and developing parallel geophysical algorithms at Petrobras. I have been part of the Geophysical Technology research group and, in 2009, helped to successfully deploy in production one of the first heterogeneous clusters with GPUs for seismic processing.

All the journey started off at UFMG in Brazil, where I have received my BSc and MSc in Computer Science advised by Professor Wagner Meira. There, I have had the opportunity to join the Speed Lab and develop efficient parallel runtime systems for data mining algorithms, also mentored by Professors Dorgival Guedes, Renato Ferreira.
