About me

I am an associate professor in computer science at Bordeaux University and LaBRI, member of the teams Logical foundations of computing and Synthesis.

My research interest is mainly in computational complexity and algorithms.

News

We released ParamExplorer, a framework developed with Julien Gachadoat for exploring parameter spaces in generative art algorithms. A companion paper is available here.
flashcluster, a Python package with a Rust backend implementing our (1+\(\varepsilon\))-approximation algorithm for hierarchical clustering, developed by Gabriel Bathie.
The full version of (1+\(\varepsilon\))-approximation for ultrametric embedding is now available on arXiv.

Background

Before moving to Bordeaux, I was a research engineer at Criteo (2021–2023), working on large-scale recommendation systems. Previously, I was a postdoc in the DeepSynth CNRS Momentum project (2019–2021) with Nathanaël Fijalkow, and before that, in the Approximation and Proof Complexity group with Jakob Nordström, Johan Håstad, and Per Austrin. I defended my PhD in 2018 at IRIF, University Paris Diderot, under the supervision of Sophie Laplante and Sylvain Perifel.
