About
Research
Sofie Brandtzæg Hårberg started as a PhD-candidate in the functional materials and materials chemistry group (FACET) at NTNU in August 2022. Her work aims to investigate the cause and mechanism of water treeing in the insulation system of subsea high voltage power cables. The research is part of the Ocean Grid project in collaboration with SINTEF Energy and Nexans, with Professor Mari-Ann Einarsrud as the main supervisor.
Background
Before starting her PhD, Sofie Brandtzæg Hårberg completed her master's degree in materials science and engineering from the Chemical Engineering and Biotechnology study program at NTNU. Her thesis was submitted in june 2022 under the supervision of Professor Kjell Wiik, and the work was on spark plasma sintering of silicon carbide.
