PhD - Research Scientist

What if, in your next adventure, you were surrounded by people who, like you, look for an unlimited playground to explore, share, and test, would you care to hear more? You've opened the right door! As an R&D team, making sure your ideas are heard and encouraged is what we strive to do!

What You'll Do:

You will be conducting a 3-year PhD in the Criteo AI Lab with an academic supervision at Inria. You will explore foundations of generative AI as we aim to study and improve generative models – GANs, diffusion / flow matching, consistency models – at the intersection of theory and practice. In particuar, we are interested in studying generative models with few-steps inference processes, as tu reduce the inference cost of state-of-the-art models. Key responsibilities include:

• study, create and implement state-of-the-art generative models for image generation,
• develop robust evaluation protocols for comprehensive experiments,
• explore advanced mathematical tools (including differential equations, gradient flows, and deep learning theory),
• engage in exploratory research with significant autonomy,
• publishing scientific papers at top-tier journals and conferences.

Who You Are:

• You have completed a Msc degree in a quantitative field (Engineering, Mathematics, Statistics, Computer Science).
• Strong background in machine / deep learning and mathematics, with knowledge of computer vision and image processing.
• Familiarity with generative models, such as GANs, diffusion and consistency models, and deep learning architectures, such as CNNs and transformers.
• Proficiency in programming languages like Python and experience with deep learning frameworks (PyTorch and / or JAX).
• Appetency for theoretical and applied scientific research.
• Good communication skills in English.
