Incidentally if you are interested in doing a PhD the University of oslo has 64 open phd and postdoc positions currently. PhDs will get a competitive salary (typically something like 50-55k USD/year, this is much higher than anything in USA for example), free healthcare, pension, in the first year you qualify for cheap student housing if you have moved from abroad, and tbh, Norway is kind of nice to live in in my opinion as long as you pick up a winter sport and don't mind the darkness.
