  • continuum-fracture method, a combination of 3D and discrete fractures
  • coupled processes in fractured rocks
  • stochastic simulations:
    • multilevel Monte Carlo method
    • Bayes inversion
  • deep neural networks as simulation surrogates
  • applications:
    • deep underground repositories of radioactive waste
    • enhanced geothermal systems
