As part of his studies at the CNSMD in Lyon, he carried out in 2010, an Erasmus exchange in the prestigious Royal  Academy  from London with Duncan  McTier, who invited him the following year to come and study in his class at the  Musik  Hochschule  der  Künste  from Zürich. 

Following an audition, he was able to follow a one-year training course (praktikum) within the Basel Symphony Orchestra, under the direction of Denis Russell Davies.
