Oscar’s Ph.D. is concerned with large-scale computational electromagnetics, focusing on topics such as the Fast Multipole Method and efficient solution of the MoM scattering problem by iterative methods and preconditioning. His Master’s Thesis from the Technical University of Denmark was on inverse problems, specifically source reconstruction, using iterative methods.
