In 2004 he became the Bolshoi's artistic director.

In 2009 he joined New York's American Ballet Theatre as artist-in-residence. Ratmansky is known for his extreme musicality, his use of the classical vocabulary of steps and movements, his revival of story ballet, and his creation of a renewed modernist ballet.
