This 'Masterpflichtseminar' is addressed specifically to master students, who intend to obtain the mantadory 'MVSem' certificate required for master studies. It is organised as a journal club, where every topic usually consists of a seminar talk by the student presenting one or more recent research papers. An additional written report of the presentation is required.

This seminar may be held in an online modus (Zoom) dependent on the Covid-19 situation. All registered students will be informed about the access data.
