Hey! I'm PhD student at ULiège, under the supervision of Prof. Gilles Louppe. My main interest are neural emulation and solutions of XDEs, and I'm currently exploring the potential of diffusion models to solve forward and inverse PDE problems. Previously, I worked as an AI researcher at appliedAI, a Munich based AI consultancy. I did a master's degree in Mathematics at the Technical University of Munich (TUM) and a bachelor's degree in Physics at the University of Leipzig. |

Gérôme Andry, Sacha Lewin, François Rozet, Omer Rochman Sharabi, Victor Mangeleer, Matthias Pirlet, Elise Faulx, Marilaure Grégoire, and Gilles Louppe (2025) project page / arXiv Appa is a large weather model (1.5B) composed of an autoencoder and a latent diffusion model. After unsupervised training, it can assimilate any kind of non-linear observations to generate plausible trajectories, in tasks such as reanalysis or forecasting. We demonstrate its strong and promising results and flexibility. |

Omer Rochman Sharabi*, Sacha Lewin*, Gilles Louppe (2024) project page / code / arXiv TMLR, 02/2025 NeuralMPM can emulate point-cloud fluid systems that include multiple materials, each with their specific properties, at over 1000 FPS, vs 15 for the original simulator. It only needs trajectories of positions and velocities to learn, bypassing the tricky tuning of a simulator. |
