Projects

This page presents a selection of industrial and research projects I have worked on. Most were carried out at CEA-List and with its industrial partners, while others were conducted independently. They primarily focus on AI for numerical simulation and scientific computing, and also extend to other areas such as geolocation and natural language processing.

LaGSplat live demo at XR DAYS 2026

OpenXR
Gaussian Splatting

Live demo presented at XR DAYS 2026. From videos alone, LaGSplat learns a 3D scene and its physics; immersed in VR, a user can interact with it while LaGSplat simulates the physics in real time. The demo also runs in 3D in the web browser.

A scene simulated by LaGSplat. Dragging inside the video applies a force to the object, and every frame is generated in real time under that force.

LaGSplat: Physics-Governed Interactive Simulation from Monocular Video

World Models
Gaussian Splatting
PyTorch

LaGSplat infers the physics of an object from a few seconds of monocular video. A visual encoder projects each frame into a low-dimensional latent space in which a Lagrangian Neural Network learns the equations of motion, and a Gaussian Splatting decoder renders the scene in real time. LaGSplat can extrapolate in time, replay the video from different initial conditions or even apply an interactive force to the scene, even though no force data was ever seen during training. Patent filed, as sole inventor. Project carried out as part of my work at CEA-List.

Impostral

Agentic AI
FastAPI
STT / TTS

Built Impostral at the Mistral Hackathon with my team: a multiplayer Turing test. A social deduction game where Mistral agents infiltrate a group of humans and try to blend in. Can you unmask the AIs before they convince everyone that you’re the AI?
🏆 1st of our task and 🥉 3rd overall. Awarded 1000 € in Mistral credits.

European Research Programme · CEA-List · 2024–2026

ARISE

NVIDIA Omniverse
PyTorch

ARISE is a European research programme aimed at designing soft industrial robots operating in close contact with human operators. Robots are trained via reinforcement learning in a physically realistic virtual reality simulation developed by CEA. My LEBNN neural network architecture (published in JMPS 2025) is used to simulate hyperelastic components of the 3D scene in real time. Project carried out as part of my work at CEA-List.

AI for indoor geolocation - Wheere

PyTorch
ONNX
Signal Processing

Freelance data science mission dedicated to indoor geolocation under severe noise and interference. Designed and implemented a full pipeline from scratch to adress this ambitious problem, including data generation, signal preprocessing, neural network architecture and post-processing. Developed an highly specialized neural network architectures operating jointly in the time and frequency domains, combining signal processing, spectral analysis, and tailored mathematical modeling. The resulting approach reduced localization error by 70% in the most degraded scenarios.
