The paper was published in the Quarterly Review of Biophysics[0] (this accepted version is materially different from the original link posted here).
Only thing I could find about Birger Sorensen's was his Linkedin page [1a] and the Immunor page where he's listed as the Chairman [1b].
Angus Dagleish looks legit, although it's notable that he did stand for Parliament in 2016 as a UKIP candidate, according to Wikipedia[2].
Can't find any primary sources for Andreas Susrud.
