Short profile and CV
Short profile	Dr. Berionni studied chemistry at the University of Paris-Sud and Versailles. He received in 2010 his PhD from the University of Versailles (Lavoisier Institute) for his research on physical organic and supramolecular chemistry under the supervision of Prof. F. Terrier and R. Goumont. In 2010 he moved to the Ludwig Maximilian University of Munich as a Humboldt postdoctoral fellow under the guidance of Prof. Herbert Mayr and Prof. P. Knochel. His post-doctoral, and independant research on organometallic and organoboron chemistry has been supported by the Alexander-von-humbolt and the DAAD Foundations. He was awarded in 2014 the Post-Doctoral prize of the Römer fundation at the Faculty of Chemistry and Pharmacy of LMU Munich.
