I am a Ph.D. student in computer science at Columbia University, working with Asaf Cidon and Roxana Geambasu. I did my undergrad in mathematics and computer science at Ecole Polytechnique, in France.
I am researching security and privacy, with a focus on differential privacy, applied cryptography and distributed systems. I enjoy solving socially meaningful problems by building practical systems that rely on sound theoretical foundations. Lately, I have been working on systems for differential privacy, applied to privacy-preserving machine learning and analytics. I enjoy contributing to open-source projects.
Feel free to contact me at pierre@cs.columbia.edu. Here is my PGP public key. I’m also on Matrix and Signal. My name is pronounced [pjɛʁ to.lo.ɲa], which sounds like “pee-air to-lo-nee-ah”.
