During those years he also lectured on missiology, Christian-Muslim relations and on the theology of interreligious dialogue at Heythrop College, at Notre Dame University in London and St John's Catholic Seminary in Wonersh (Guildford).
Rocco has been working in Japan since 2014. He is presently Interreligious Dialogue coordinator for the Xaverian Missionaries, and serves Catholic Archdiocese of Osaka as director of the Commission for Interreligious Dialogue and as director for Ecumenical Affairs. In March 2018 he was very recently appointed as a member of the Sub-Commission for Interreligious Dialogue of the Catholic Bishops' Conference of Japan.
He has been an associate to the Heythrop Centre for Christianity and Interreligious Dialogue and the Heythrop Centre for Easter Christianity (UK) for many years, and a member of the Interantional Association of Catholic Missiologists (IACM) since 2011.

His academic interests include: the theology of Interreligious Dialogue, especially in the Catholic tradition and teaching, and the theology of Benedict XVI; Jewish-Christian Relations; historical and contemporary perspectives on Muslim-Christian dialogue, with a particular interest in the thought of Louis Massignon; Christian-Buddhist dialogue, with a special focus on Japanese Buddhism. He has recently developed an interest in the relationship between Christianity and Shinto, and on the relationship between Christianity and the Tea Ceremony, which he started practicing a year ago as a way of deepening his knowledge and understanding of Japanese culture and religiosity.
