Short CV

Current Research

My PhD subject is related to Worst-Case Execution Time (WCET) and Verified Compilation. This research is at the intersection of the fields of formal verification (more specifically, mechanical verification with the help of a proof assistant) and static WCET estimation. There are two directions to this research:

  • To formally verify state-of-the-art WCET estimation techniques, proving their soundness;
  • To benefit from the semantics and the framework of a formally verified compiler (namely, the CompCert project) to produce formally verified WCET estimation techniques.

There is a strong concern about the correctness of the obtained results. The analyses are proven correct with respect to the semantics of the compiler’s intermediate representations using the Coq proof assistant.

  • PhD Research
    • The formal development results related to my thesis are available online. This page includes links to the Coq proof scripts.

Past Research

I’ve done a bit of research (or research-related work) on a few different subjects:

  • Document (image) structure analysis: during my Masters’ internship, I worked on a high-level grammar-based formalism to “parse” structured images of documents (such as handwritten letters, tabular forms, musical scores, etc), the DMOS method.
  • Graph visualization techniques: during a short visit at NICTA Canberra, Australia, I participated in the improvement of an interface to visualize large dynamic constraint graphs.
  • Information visualization: during my undergraduate studies in Computer Engineering at UNICAMP, I did some development related to how to best present numeric/qualitative information using colors, shapes, sizes, etc.
