He has conceived numerous original contributions in theoretical particle physics, and is one of the originators of string theory, which continues to be a very active research area worldwide. Many concepts in high energy physics are named after him, such as the Nielsen-Olesen vortex, the Nielsen-Ninomiya no-go theorem and the Koba-Nielsen variables in string theory.

He has received the highly esteemed Humboldt prize for his scientific work, is member of the Royal Danish Academy of Sciences and Letters and the Norwegian Acadamy of Sciences and Letters. Furthermore, he has been extremely active in popularizing science at many levels.
