His research showed the pivotal role that Byzantine scholars who emigrated to Italy played in unlocking and interpreting ancient Greek texts vital to the Italian Renaissance, systematically documenting their interactions in the West. He deeply probed the encounters between the Greek and Roman churches over centuries of recurring schism and attempted reunion, including the Councils of Lyons, Basel and especially Florence, during which the churches agreed to reconcile.
