About me
I am currently a final-year PhD student at Sorbonne Université, ISIR (MLIA Team), under the supervision of Patrick Gallinari. My research focuses on deep learning methods for PDE solving, with a particular emphasis on operator learning and generalization for parametric PDEs and multi-physics problems. Current directions I am exploring include:
- "Decoder-only" transformer operators for PDEs
- Generative modeling for PDEs
- Learning in representation space for PDEs
- Uncertainty quantification
