Short Bio

Since August 2025, I am the Models team lead at Karavela.ai, a startup building a foundation model of the brain. Using next-gen magnetic resonance, Karavela is collecting the largest dataset of the human brain’s dynamics to enhance clinical trials with AI and crack brain decoding.

I work at the intersection of applied mathematics, signal processing and machine learning, with a focus on making scalable methods for neuroscience modalities (MEG, EEG, fMRI).

From November 2022 until July 2025, I was a postdoctoral researcher at Inria Saclay in the Mind team, supervised by Bertrand Thirion, Alexandre Gramfort and Rémi Flamary.

From October 2019 until October 2022, I did my PhD at the SONDRA laboratory at CentraleSupélec, University of Paris-Saclay. My supervisors were Jean-Philippe Ovarlez, Guillaume Ginolhac, Chengfang Ren, and Arnaud Breloy.

I previously graduated from the University of Technology of Compiègne with a major in Computer Science and a minor in Mathematical modeling.

In parallel, I have been a part-time lecturer at École Polytechnique, CentraleSupélec and University Paris-Saclay, teaching graduate-level applied mathematics, including optimization, digital signal processing and machine learning.
