Tamuna was born in Tbilisi, capital of Georgia, on the 12th of February 1971, daughter of Vakthang Sirbildadze and Nunu Ghurchumelia. She started her life together with her elder sister Keti. Already in nursery-school in Lermontowstreet she loved drawing and painting and impressed her teacher so much that she organised an exhibition for the six year old. In 1989, Tamuna graduated from high school in the Rustaveli-avenue. From 1989 to 1994 she studied at the state-acadamy of art in Tbilisi, where she gained a degree. After moving to Vienna in 1997, she studied until 2003 at the Academy of Fine Arts, where her teacher was Franz Graf. In 2003 she further extended her studies at the Slade School of Fine Art in London. In the meantime she had met the artist Franz West, whom she married in 2002, and with whom she collaborated on several art-projects and works until his death 2012. Her last years she lived together with Benedikt Ledebur. Always very active, she was included in a group exhibition as soon as she moved to Vienna. Over the years she made a huge body of works encompassing installative works, videos, site-specific projects and an enormous amount of paintings, which she exhibited in various exhibitions in galleries and museums all over Europe. In the last two years she not only participated in the group show Artists and Poets in the Secession in Vienna, curated by the artist Ugo Rondinone, and in the group show No Man's Land of the Rubell family collection in Miami, but also had a lot of critical acclaim for two solo-shows in New York. Her last show at Almine Rech gallery in Brussels opened shortly before her death.
