Can we say, ‘He is a faculty at Osmania University’?

The word ‘faculty’ is normally used to refer to all the teachers in a particular department or university. In this sense, it is like the word ‘staff’. Just as you cannot say ‘He is a staff’, you cannot say, ‘He is a faculty’. If you wish to refer to a particular individual, then you have to say, ‘He is a member of the faculty’ or ‘He is a faculty member.’
