At university, Alexander Zeldin created a production of Calderon de La Barca's Constant Prince in Cairo, working with local musicians. After graduating, he began work at the Mariinsky Opera directing the Russian premiere of Powder her Face, as well as works by Puccini and Ravel. In 2010 he was selected to helm the European Theatre Company at the Napoli Teatro Festival Italia, collaborating again with artists from the Middle East on a production of Romeo and Juliet in Arabic and Italian. In 2011, he was invited to South Korea to direct Macbeth with Yi Youn Taek's Goripae Group (Korean Critics' Choice) and in January 2012, he created a new music and dance-theatre work, "Shemehé", for the British Council-National Theatre Studio-Rustaveli, National Theatre Georgia and Black Battles with Dogs at the Southwark Playhouse. In 2013, he assisted Peter Brook and Marie Helène Estienne on their revival of A Magic Flute. He has also collaborated with dancer Mélanie Lomoff on Code Unknown (Opera Estate/ Bassano Del Grappa, Mousonturm Frankfurt). Since 2011, Alexander Zeldin has formed an ensemble of actors in the UK. Their projects include Doing the Idiots (National Theatre Studio 2012 - a response to Lars Von Trier's film The Idiots), Shemehe and Beyond Caring (Yard Theatre, 2013).

His work has been recognised by a nomination to the Rolex Mentor Protege Award in 2012, for the leading young artistic voices of the future.
