Γεννήθηκε το 1948 στην Αθήνα, όπου και σπούδασε στην Ανωτάτη Σχολή Καλών Τεχνών. Έχει επιρροές από το Παρίσι  στο οποίο έζησε  από το 1978 ως το 1992. Οι συνθέσεις του έχουν κάτι το μνημειώδες,  όχι μόνο γιατί πολλές φορές είναι μεγάλων διαστάσεων  αλλά και για τον τρόπο που τις αποδίδει. Είτε καταπιάνεται  με θέματα της καθημερινότητας είτε εμπνέεται  από περασμένα βιώματα. Η ζωγραφική του, που αναπτύσσεται  σε ένα χώρο με ιδιάζουσα  ατμόσφαιρα, είναι αφηγηματική.

Born 1948 in Athens. Studied at the Athens School of Fine Arts under Nikolaou and Moralis. Has held more than 20 solo exhibitions in various cities in Greece and in Paris. Has participated in more than 15 group exhibitions, most of them in France. In 2002 the Foundation for Hellenic Culture in New York held a retrospective exhibition of his work.

Samios's career began in the late 1970s with the series Nudes and Night cafes. His removal to Paris in 1978 meant that his portrayals of cafe life were now set in the French capital.

He has experimented throughout his career with a variety of materials and techniques, including fresco and encaustic, and depicted scenes from a number of human activities, occupational or not, dramatic or day-to-day. His personal experiences influence his subject matter and style. The emotional tension of the figures in his works plays a leading role. Portraits, couples, and still lifes are rendered realistically, but as if through a surrealist prism, forming unnatural and multiple angles of vision on the same painted surface and isolating details of objects and persons in fragmented form. The figures usually move in a gently familiar, everyday ambience, which seems to be located somewhere beyond conventional time.
