The 4th edition of the IDAEA Young Researchers’ Day (YRD) was held on December 14th in an onsite format. A total of 126 people attended the event, including post-docs, technicians, and principal investigators, demonstrating one year more, the complete success of the event. All the attendees could learn from the hard work carried out by the IDAEA PhDs in different dynamics: oral presentations, flash talks, and poster presentations in groups. The programme covered the participation of 41 PhD students who explained their scientific research in three different formats: 12 oral communications, 13 flash talks, and 16 posters.

The special workshop of this YRD edition was on scientific graph design, conducted by Mikel Rodríguez (Mikel Graphic Science), Illustraciencia’s academy teacher. Although theoretical, the workshop was useful for PhDs to better design graphical abstracts and figures.
