Update: As of September 2016, I'm working for Apple Inc.
I am a Ph.D. candidate in the Department of Computer Science, Brown University, advised by Rodrigo Fonseca. I hold a Master's degree in Computer Science from Brown (2011), a Master's degree in Information Science and Technology from the University of Tokyo (2009), and a B.S. degree in Computer Science from the Federal University of Minas Gerais, Brazil (2005).
I am primarily interested in Operating Systems and execution environments and how they can be better designed to fit current user needs. My research focuses on cross-layer instrumentation and profiling of an application's behavior and energy consumption as it executes through a deep-layered software stack.
I am currently working on lightweight tools to correlate measured power draw with the execution trace of mobile apps. My plan is to use correlated data to identify energy hotspots and make your smartphone battery last longer by adapting the behavior of software at runtime.
