Gălățanu took up fencing at CSM Iași under the coaching of Iulian Bițucă. He joined the national team after the 2012 Summer Olympics, when three of its four members retired from sport. His first competition with the team was the Madrid World Cup, where Romania earned a bronze medal. In the 2013 European Championships in Zagreb he reached the quarter-finals, where he was defeated by his captain Tiberiu Dolniceanu. In the team event, Romania were overcome by Italy in the semi-finals, then by Ukraine in the small final, and finished 4th.
