Gilles Puy

Research scientist at valeo.ai

I am a Senior Research Scientist at valeo.ai and part of the astra-vision team at Inria. My work focuses on annotation-efficient learning (self-supervised learning, unsupervised learning, etc.), multimodal learning, and 3D vision.

Before joining valeo.ai, I was a researcher at Technicolor/Interdigital R&I (2016-2019), and a postdoc at Inria (2014-2016). I obtained my PhD from EPFL in 2014. I obtained my M.Sc. in Electrical and Electronics Engineering from EPFL and the Engineering Diploma from Supélec in 2009.

Note: In September 2025, we discovered that our RangeViT paper was being cited in a substantial number of likely LLM-generated papers, most of which were uploaded to ResearchGate over a very short period of time. Following our report, ResearchGate investigated the issue and removed approximately 200 such papers. However, these papers remain indexed on Google Scholar as of now.
