Professor Hubert J. M. Hermans is a Dutch psychologist renowned for developing Dialogical Self Theory (DST), which bridges psychology with social and cultural influences. Earning his Ph.D. from Radboud University Nijmegen, he initially focused on motivation and self-concept, later pioneering DST in the 1990s. Inspired by William James and Mikhail Bakhtin, he proposed that the self is not singular but consists of multiple “I-positions” that engage in internal dialogues. His Self-Confrontation Method (SCM) has been widely used in psychotherapy and personal development. Hermans’ work has had a profound impact on counseling, intercultural studies, and narrative psychology, shaping modern understandings of identity in an increasingly globalized world. He has published numerous books and scientific articles, including “The Dialogical Self in Psychotherapy and Handbook of Dialogical Self Theory”, which remain foundational texts in psychology. His work continues to influence modern discussions and research on identity, motivation, and personal development in an increasingly interconnected world.

Philia Issari is Professor of Counseling Psychology in the Department of Psychology at the National and Kapodistrian University of Athens (NKUA). Her writing work includes articles in international and Greek scientific journals and chapters in collective volumes. Her scientific interests are focused on issues of identity, dialogicity, and the embodied dimension of the self, ethnic identity, cultural experience, multicultural counseling, health counseling, adolescent and student well-being, school bullying, and qualitative research methodology with an emphasis on narrative analysis.

Georgia Gkantona is Assist. Professor of Counseling Psychology at the Department of Psychology of the University of Ioannina.

She has been trained in Systemic Psychotherapy and is a member of the European Family Therapy Association (EFTA). She is also a member of the International Society for Dialogical Science (ISDS), as in recent years her psychotherapeutic approach has been significantly informed by H. Hermans’ Dialogical Self Theory. Her research interests focus on the study of the individual’s internal dialogical activity and the development of dialogical techniques and methods of counseling and psychotherapy.

Vladimir Džinović (1977) is a Doctor of Psychology and a licensed constructivist psychotherapist. He is a senior research associate at the Institute for Educational Research in Belgrade. In his research practice, he applies constructivist psychology, dialogical self theory and social constructionism in the research of identity, mental health and professional development. He is a leading national expert in qualitative research, especially in the methodology of personal constructs and the analysis of the multivoiced self, within which he developed an innovative approach called the Methodology of the agonistic self (MAS-M). He has 22 years of continuous therapeutic experience. In his psychotherapy work, he combines the therapy of personal constructs with dialogic, narrative and psychodramatic approaches.
