Study panel member, a magician (8)
I believe the answer is:
conjuror
'a magician' is the definition.
(conjuror is a kind of magician)
'study panel member' is the wordplay.
'study' becomes 'con' (I've seen this before).
'panel member' becomes 'juror' (I've seen this before).
'con'+'juror'='CONJUROR'
(Other definitions for conjuror that I've seen before include "A sleight-of-hand entertainer" , "Prestidigitator" , "One performing tricks" , "One who might put woman in box" , "Illusionist, magician" .)
