I am a postdoctoral researcher at CMU working with Anupam Datta and Matt Fredrikson. I am interested in programming languages, formal verification, and computer security.
I am from Campinas, SP, Brazil. I pursued my Ph.D. studies at the University of Pennsylvania, under the supervision of Benjamin Pierce and co-advised by Cătălin Hrițcu. Prior to that, I was a student at Unicamp and at Polytechnique. I am one of the authors of Software Foundations, an introductory textbook to the Coq proof assistant. I also have a blog about Coq.
July 2018 Our paper When Good Components Go Bad (arxiv) was selected to appear at CCS 2018.
July 2018 Our newest draft, Metric Semantics for Probabilistic Relational Reasoning, is out on the arxiv.
June 2018 I will be joining the artifact evaluation committee of POPL 2019.
February 2018 A draft of our new paper on secure compilation, When Good Components Go Bad, is out on arxiv. Check also the accompanying Coq formalization on GitHub.
January 2018 Our paper The Meaning of Memory Safety (arxiv) was accepted at POST 2018.
September 2017 I served on the external review committee for PLDI 2018.
