 The Juelich Challenges is a JULAIN initiative for 2 years now. It is recognized by our board of directors, and the hackathon was even announced in the institute’s directors meeting with a request to spread the word and to encourage young researchers to participate. Thus, don't hesitate to ask your working group leaders to participate in the hackathon for these 4 days.
