Guðjón Ketilsson studied Fine Art at the Academy of Icelandic Art and at Nova Scotia College of Art and Design, Canada.
He mainly works with drawing and sculpture, mostly from wood.
The human body is central to his works, its absence and/or its very presence. His study of the human condition is through its primary vehicle, the body. He explores time, memory and history through details of our everyday connection to our own bodies, from our clothing and hairdo´s, to shoes that change and adjust to the size, temperature and movement of the body.

Ketilsson has had over thirty solo-shows and has participated in numerous group-shows in Iceland and internationally, such as in the Nordic countries, The Netherlands, Spain, USA, Canada, China and Australia.
His works can be found in the collections of the major Icelandic art museums and some abroad, as well as in private collections.

He has participated in various international residencies and has been selected for numerous competitions of art in public spaces.
Ketilsson received the DV-Cultural Prize in 2000 and the Einar Jónsson Art Museum Award in 2001, in Iceland.
