Jean-Daniel Julien received his master’s degree in physics at the École Normale Supérieure de Lyon (ENS Lyon, France) in 2012. As a Ph.D. student, he worked on the mechanics and growth of plant morphogenesis, using computational approaches, in the Physics laboratory and the Plants Reproduction and Development laboratory of the ENS Lyon. In 2015 he was a graduate fellow at the Kavli Institute for Theoretical Physics (Santa Barbara, United States). His domains of interest are continuum mechanics, non-linear physics, statistical mechanics, and scientific programming. He joined the group in January 2016. Jean-Daniel then joined the Institute for Fluid Mechanics in Toulouse.
