He studied at University College, Economics and Philosophy at the School of Economic Science and Sanskrit at the School of Oriental and African Studies, London, and did a post-graduate at SOAS and at Deccan College in Pune. He taught in London and Athens. Since 1980 he led the Omilos Meleton Cultural Institute. He is on the Editorial Board of Adyar Library Bulletin. Beginning in 1997 Kazanas accepted the Vedic Tradition[disambiguation needed] and its place in the broader Indo-European culture.
He was one of the few contributors in a special volume of the Journal of Indo-European Studies on the Indo-Aryan migration theory who argued against the theory. Kazanas' paper was criticized by nine scholars, among them JP Mallory. In the latter issue of the Journal of Indo-European Studies, Kazanas responded to all his critics in the article ‘Final Reply’.
