Yiorgis is merely interested in the dynamics of change. He chooses to photograph the human-altered landscape not only because it illustrates the rapid socio-political changes that have been punctuating the landscape and habitat in the past years, but also because this type of representation as a genre coincides with a significant change in the photographic imagery itself.
He studied photography at the Technological Institute of Athens and architecture at the Aristotle University of Thessaloniki, Greece. He subsequently pursued a graduate degree at Goldsmith's College, University of London, and completed his Ph.D. at the School of Art and Design of the University of Derby, UK. Yiorgis's photographic work has been published in a number of books on landscape and architectural photography. He was also a lecturer in photography at the School of Architecture, University of Thessaly from 2008 to 2011.
In addition to his academic work, he exhibits his work in solo and group art exhibitions in Greece and abroad. His research interests include the process of beautification of landscape in contemporary photography, the construction of identity through lived-in space. In 2008, supported by a Fulbright scholarship, he travelled the US by car from East to West and back focusing on the American landscape and how its visitor-user perceives it. He recently participated in the Venice Biennale of Architecture with large scale works of the city of Athens and since 2007, Yiorgis is the official photographer of the construction of the Stavros Niarchos foundation Cultural Center.
