About

I am a CNRS research scientist at IRIF, Université de Paris. I received my PhD from École Normale Supérieure de Paris (ENS) in November 2017, under the supervision of David Pointcheval and Hoeteck Wee. In 2017 – 2019, I was a postdoctoral researcher at Karlsruhe Institute of Technology (KIT), in the team of Dennis Hofheinz.

My main research interests are secure multiparty computation and zero-knowledge proofs (both foundational and practical aspects), as well as the theoretical foundations of cryptography. For an up-to-date list of my publications, you can check my publication page, my dblp profile, or my Google scholar profile. All my publications become available at some point in open access format on the ePrint archive; see the list here. My PhD thesis can be found here.

Students and postdocs

I have the pleasure to advise several amazing PhD students, and I will not be accepting any new PhD requests in the next few years. However, if you are interested in doing a postdoc on topics related to secure computation next year, I will likely have one or two openings. Drop me a mail, and consider applying to the openings of the Algorithm and Complexity team of IRIF (around October 2021).
