Oscar received the M.Sc. degree in mathematical engineering from the Technical University of Denmark, Lyngby, in 2011 and started immediately at TICRA as an industrial Ph.D. student. Oscar’s Ph.D. project was entitled “Algorithms for Electromagnetic Scattering Analysis of Electrically Large Structures” and focused on implementing the Multi-Level Fast Multipole Method (MLFMM), for use with TICRAs Method of Moments solver, as well as accelerated evaluation of fields from surface current densities. Oscar received the Ph.D. degree in 2015 and is now with TICRA where he is working on software development for TICRA's main software packages.
