Focussing rather on questions and their wide-ranging discussion instead of presenting results, PhD researchers pitch hypotheses and float ideas. Making use of the online setting, they invite one virtual guest of their choice from their field of question and extend the discussion to all participants. This way, they share what they are working on and actively make use of the broader knowledge of the HvdV research community. There will be two sessions each semester with two PhD researchers each session. No registration required. Moderation: Mario Rinke
