This first annual Doctoral Students' Day was organised on 05 April 2023 to give young MIO researchers the opportunity to present their research work.
It is also an ideal opportunity to bring together the unit's staff (scientific and administrative) in a studious and convivial atmosphere.
A warm thank you to everyone who got involved, especially the doctoral students Emma, Hélène, Lauralie, Laurina, Marie and Marine.
After an introductory speech by Gérald Grégori, Deputy Director of the MIO, the morning was given over to presentations of the subjects of our doctoral students' theses.
The afternoon was devoted to poster presentations and informal scientific discussions.
