Research Internships

2019 Internship

In 2019, I did an internship at IRISA, about formal verification of just-in-time compilation. This work was supervised by Sandrine Blazy and David Pichardie. Internship Report.

2018 Internship

In 2018, I did an internship at Princeton University, about verifying a B+Trees Library using VST. This work was supervised by Andrew Appel and part of the DeepSpecDB project. Internship Report.

2017 Winter Internship

In Winter 2017, I did an internship in the University Federico II in Naples, about Changing Observation in Epistemic Temporal Logics. This internship was supervised by Aniello Murano, Bastien Maubert and Sasha Rubin. Internship Report.

2017 Summer Internship

In Summer 2017, I did an internship with the Software Foundations Laboratory in Seoul National University, about implementing integer-pointer cast semantics in CompCert. This internship was supervised by Chung-Kil Hur. Internship Report.

2016 Internship

In 2016, I did an internship in the CELTIQUE team (IRISA Rennes), on high level Worst Case Execution Time (WCET) estimation using Abstract Interpretation and Constraint Programming. This internship was supervised by Charlotte Truchet and David Cachera. Internship report (in French).
