P.D. meaning in International ?

Privatdozent (for men) or Privatdozentin (for women), abbreviated PD, P.D. or Priv.-Doz., is an academic title conferred at some European universities, especially in German-speaking countries, to someone who holds certain formal qualifications that denote an ability (facultas docendi) and permission to teach (venia legendi) a designated subject at the highest level. To be granted the title Priv.-Doz. by a university, a recipient has to fulfill the criteria set by the university which usually require excellence in research, teaching, and further education. In its current usage, the title indicates that the holder has completed her/his habilitation and is therefore granted permission to teach and examine students independently without having a professorship.
