PhD Alumni/ae Club

We intend to connect Alumni/ae with each other and with current members of the VDSEE, the Faculty of Life Sciences and the University of Vienna and create mutually beneficial relationships.

We aim to establish an Alumni/ae programme in the future! If you want to be included in the VDSEE Alumni/ae Club, please send an email to docschool.vdsee@univie.ac.at

You can also join the general Alumni/ae network from the University of Vienna. Further information can be found here.
