Yannis Michas was born in 1938 in Athens. He initially studied at the studio of K. Eliades (1955-1958) and continued his studies at the École des Metiers d'Art in Paris (1958-1962). He was a member of the Chamber of Fine Arts of Greece, the group "Processes-Systems", the Association of Contemporary Art and Société Européene de Cullture.
In both his painting and sculpture, influences from geometric abstraction and constructivism are evident from his early works from 1965-1970. In the 1970s he began to create reliefs and wall compositions, and in the 1990s he returned to painting mainly in oil. He passed away in 2008.
