A probabilistic white‐box model for PDE constrained inverse problems
PAMM, 2018AbstractInstead of employing deterministic solvers in a black‐box fashion, we seek to address the inherent challenges of uncertainty quantification by restating the solution of a PDE as a problem of probabilistic inference. In doing so, state variables are treated as random fields, constrained or mutually entangled by underlying physical laws.

A multilevel algorithm for inverse problems with elliptic PDE constraints
Inverse Problems, 2008We present a multilevel algorithm for the solution of a source identification problem in which the forward problem is an elliptic partial differential equation on the 2D unit box. The Hessian corresponds to a Tikhonov-regularized first-kind Fredholm equation.

Stochastic Algorithms for Inverse Problems Involving PDEs and many Measurements
SIAM Journal on Scientific Computing, 2014Inverse problems involving systems of partial differential equations (PDEs) can be very expensive to solve numerically. This is so especially when many experiments, involving different combinations of sources and receivers, are employed in order to obtain reconstructions of acceptable quality.

Inverse problems for DEs and PDEs using the collage theorem: a survey
International Journal of Applied Nonlinear Science, 2013In this paper, we present several methods based on the collage theorem and its extensions for solving inverse problems for initial value and boundary value problems. Several numerical examples show the quality of this approach and its stability. At the end we present an application to the Euler-Bernoulli beam equation with boundary measurements.

Anisotropic variational models and PDEs for inverse imaging problems
2019In this thesis we study new anisotropic variational regularisers and partial differential equations (PDEs) for solving inverse imaging problems that arise in a variety of real-world applications. Firstly, we introduce a new anisotropic higher-order total directional variation regulariser.
