News: Design Miami co-founder Ambra Medda has started a new role as global creative director for the 20/21 Design department at Christie's auction house.

London-based Christie's announced Medda's appointment as the head of its specialist department dedicated to 20th and 21st century furniture, lighting, ceramics and sculpture pieces.

Medda's appointment is the latest in a flurry of management changes at the auction house, which named Patricia Barbizet as its new CEO in December.

Medda is the co-founder and creative director of L'ArcoBaleno, an online retail brand that offers contemporary collectible design alongside industry reports, which launched in 2013.

She co-founded Design Miami – the annual limited-edition fair that coincides with Art Basel – with developer Craig Robbins in 2005 before leaving her role as director five years later.

"Ambra brings this extensive experience and her strong partnerships with the world's most respected cultural organisations, educational institutions, brands and designers to her new role at Christie's," said a statement from Christie's.

The Greece-born curator has previously independently organised shows for contemporary art collective Stareleene, and has co-curated a group exhibition for the Lower East Side Girl's Club.

Christie's holds 20/21 Design sales twice annually in New York, Paris and London. It's last New York sale on 9 December, which included a collection of rare Art Deco furniture as well as pieces by Marc Newson and Ron Arad, raised over £4.6 million.
