The annual DocDay VT 2021

is a mini conference type event, intended to provide a forum for the PhD's to present their research and / or research proposals in order to get a feedback from fellow colleagues and expand their connection network with other PhDs, PostDocs and Professors active in our Doctoral School.

In accordance with the "Curriculum for the Doctoral Programme in Technical or Natural Sciences" in the version of 2019, and is in force since October 2020, all PhDs are required to present their research proposal and their work schedule publicly in the first year of their PhD studies. This public presentation is scheduled during the DocDay VT.

It is strongly advisable the PhDs participate in this event and their participation is active (i.e. submission of an abstract for oral or poster presentation). It will allow them to gain credits for their PhD studies, as a presentation will count for the completition of the course 669.007 "DissertantInnenseminar / PhD student's seminar", which is a compulsory course in our doctoral programmes.
