Problematic posers for university academic (9)
I believe the answer is:
professor
'university academic' is the definition.
(I've seen this before)
'problematic posers for' is the wordplay.
'problematic' is an anagram indicator.
'posers'+'for'='posersfor'
'posersfor' is an anagram of 'PROFESSOR'.
(Other definitions for professor that I've seen before include "Head of university department" , "Leading academic" , "chairman?" , "Senior member of college faculty" , "Member of an academic faculty" .)
