You should not call women profs Madame or Hanim or Mrs or Ms; nor call male profs as Mr or Bey. The correct form of addressing is Prof. X (Hi Prof. Berrin) or X. hoca (Hi Berrin hoca) in Turkey.

I recently learned that some Asian students are taught to call profs as Ms. but in general this is frowned upon in Turkey or US…

Have a good semester.
