Bridging between actors involved in AI and data governance, this workshop gathers a multidisciplinary group of academics, policy makers, and practitioners - with a special emphasis on early-career researchers. Participants will exchange ideas and knowledge on the challenges related to trustworthy use and development of AI, AI regulations, data protection, and public sector digital transformation. The workshop is structured as follows: opening (5 minutes); short presentations of 5 promising early-career researchers from the fields of trustworthy AI, data privacy, and public sector digital transformation across different disciplines including law, ethics, and computer science (15 minutes); world-café discussions, where participants will join each researcher at their respective table to discuss their research and explore practical implications and policy challenges in agreeing efficient but consistent AI governance mechanisms (45 minutes); conclusion with reflection on the discussions and lessons learned (10 minutes).
