Invited Talks

Talks of the GPSD 2021 are organised in 14 sections. During the conference week there will be sessions consisting of

  • live invited talks of 20 minutes,

  • live discussions of contributed prerecorded videos (availabe before and during the conference on a separate YouTube channel).

Researchers of all levels are very welcome to participate in the discussions with or without own contributions! If you have never contributed a prerecorded talk to a conference, check out the suggestions collected here.
