  • Extending advisor’s ICLR 2025 latent-space-translation framework for subsurface forward/inverse problem to using Diffusion priors and flow matching.
  • Working on optimal-transport-based misfit functions (Wasserstein distance, unbalanced OT) as an alternative for L2 loss to mitigate cycle-skipping on Marmousi/Overthrust benchmarks.
  • Literature survey on diffusion- and flow-matching-based generative priors as regularizers for Bayesian FWI.
