Nora Lüthen defended her PhD thesis

Today, Nora Lüthen successfully defended her PhD thesis entitled “Sparse spectral surrogate models for deterministic and stochastic computer simulations”. [Slides]

In her work, Nora compared and further developed techniques for sparse polynomial chaos expansions (optimal experimental designs, solvers, adaptivity strategies) [external page 1,external page 2]. She further investigated Poincaré chaos expansions for applications to global sensitivity analysis [external page 3]. Finally, she developed a trajectory-based emulator for stochastic simulators [external page 4].
