I build AI methods and systems for scientific discovery and engineering.

My work spans computer vision, machine learning, tensor methods, and neural operators. At NVIDIA Research, I lead the AI-Aided Engineering group, developing methods and open-source systems for simulation, prediction, and design.

About

Why this work.

I develop AI methods and systems that help engineers and scientists accelerate simulation, prediction, and design. The aim is to preserve the structure of physical problems, their geometry, conditions, and regimes—while making computation fast enough to change how ideas are explored.

Today I lead the AI-Aided Engineering group at NVIDIA Research, where we advance Physics AI across engineering, weather, and materials. Open source is central to that work: I created and lead TensorLy and NeuralOperator, making advanced tensor and operator-learning methods easier to use, extend, and apply.

Before NVIDIA, I was a founding member of the Samsung AI Center in Cambridge. My academic training spans mathematics, computer science, and AI. I earned a French engineering degree (Diplôme d’Ingénieur) in mathematics, computer science and finance, alongside a BSc in Advanced Mathematics. I then earned an MSc in Advanced Computing with Distinction from Imperial College London, followed by a PhD in Artificial Intelligence at Imperial under the supervision of Professor Maja Pantic in the i.bug group.

Signature work

Open, tested code.

ATLAS

Industry impact

Probabilistic medium-range weather forecasting.

I led the development of ATLAS, a transformer that produces large forecast ensembles orders of magnitude faster than traditional numerical weather prediction.

Research agenda

Learning systems grounded in the physical world.

Neural operators

Learning mappings between function spaces so models can transfer across resolutions, geometries, and physical regimes.

Geometry and conditioning

Building architectures that respect irregular domains, boundary conditions, and the structure of engineering problems.

Efficient tensor learning

Using multilinear structure to make large learning systems more compact, expressive, and computationally efficient.

Design under uncertainty

Turning fast learned surrogates into useful tools for optimization, exploration, and real engineering decisions.

Research in practice

From simulation to interactive design.

The goal is not a faster benchmark in isolation. It is a model that preserves physical structure, generalizes across design changes, and becomes useful inside the engineering loop.
