I am a Ph.D. student in computer science at Columbia University, working with Asaf Cidon, Roxana Geambasu and Mathias Lécuyer.
My research is about privacy-preserving systems, at the intersection of differential privacy, applied cryptography and distributed systems. In particular, I’ve been working on infrastructure systems for differential privacy, such as privacy budget schedulers, protocols for privacy-preserving distributed analytics or large-scale private training of language models.
More generally, I enjoy solving socially meaningful problems by building practical systems that rely on sound theoretical foundations. I also like contributing to open-source projects.
A bit more about me: I did my undergrad in mathematics and computer science at Ecole Polytechnique, in France. My name is pronounced [pjɛʁ to.lo.ɲa]. Feel free to contact me at [email protected].
