Since October 2020, I work at the CWI in Amsterdam, in the crypto group led by Ronald Cramer. Before that, I was a PhD student at Inria in Paris, in the project-team COSMIQ (formerly SECRET), under the supervision of Nicolas Sendrier, with a grant from the Sorbonne Université.


My primary research interest is the design and analysis of code-based post-quantum cryptosystems, that is cryptosystems resistant to attacks using quantum computers. I have been working on the security analysis of code-based cryptosystems proposed in response to the call for post-quantum cryptography standardization issued by the National Institute of Standards and Technologies (NIST).
