About
Background:
The spring of 2016, I finished my masters at NTNU in Applied Physics. My thesis was titled “The Vacuum Polarisation Contribution to the Lamb Shift Using Non-Relativistic Quantum Electrodynamics”.
Research:
I started my PhD at the Department of Physics the fall of 2016. The project is titled “Multiscale Modelling of Deformations in Aluminium Alloys” and affiliated with SFI CASA - Lower Scale.
