Nikos Tsouknidas was born in Greece. He studied computer programming and electrical engineering in Athens before moving to Japan to study strategic design. He then moved to London, where he now lives and works for the BBC as a lead data engineer in machine learning. But Nikos has a double -- Tsouk -- who works nights as a comics artist. He's the one who, in 2023, published "Portraits," his first graphic novel (Dargaud/Europe Comics).
