I am a postdoctoral researcher at the CWI in Amsterdam, in the crypto group led by Ronald Cramer. Prior to that, I completed my PhD thesisat Inria and the Sorbonne Université in Paris, under the supervision of Nicolas Sendrier.


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).
