One of his main interests is in the social aspects of computing. Panayiotis was a panelist at the HCI for Peace panel during CHI 2011. Panayiotis will bring the perspective of coming from a part of the world that has seen armed conflict in his lifetime and where people from the two sides of the conflict have not always been allowed to communicate. Panayiotis helped setup mailing lists in the 1990s to bring people together and discuss ideas. He later helped develop social media applications to report news across the dividing line. Recently, Panayiotis supervised a new project (funded by the Fulbright foundation) to develop online tools to facilitate peace and mutual understanding among groups in conflict.
