When prepostion and the infinite article can be omitted?

I read a sentence yesterday .
Cambridge university , earth scientist ,Sebastian Breitenbach is a co-author of the study.
My question is
(1) Cambridge university ,why the propostion at is omitted
(2) earth scientist ,why the indefinite article an is omitted.

Pay attention to the use of commas. There should be no space before a comma. The sentence should be: Cambridge University earth scientist Sebastian Breitenbach is a co-author of the study.
