The DIMEC PhD Programs are pleased to present the fourth edition of the Learn & Share event, an important opportunity for PhD students to present and discuss the progress of their research projects. The presentation of research results, in the form of posters for second-year PhD students and oral presentations for third-year students, in addition to being preparatory for the PhD student's admission to the next year, is an opportunity to promote new collaborations and synergies, which are essential to enrich each PhD student's journey. The best posters will be awarded in recognition of the commitment of our young researchers. On the opening day, we will have the honor of hosting two exceptional speakers of international standing, who will be of great inspiration to all PhD students and participants.
