He is also the Principal Investigator of the project “Trinitarian Ontologies: A New Philosophical Investigation into Trinitarian Relationality” (2024–2026). Since 2024 he is a member of the editorial board of the Czech edition of ICR Communio. Since 2023, he serves as a member of the scientific board of the Jan Amos Komenský Museum in Uherský Brod and as a member of the editorial board of the journal Studia comeniana et historica. In 2023 he was honoured by being called a full member of the Geisteswissenschaftlichen Klasse, Sudetendeutsche Akademie der Wissenschaften und Künste (München). In the past, he has participated in the project “Trinitarian Ontology of the Human Person” at Charles University in Prague (2021-2023), and co-organized the international conference on Trinitarian Ontology and Personalism in Prague (2023) as well as the New Trinitarian Ontologies EuARe Panel in Münster (2021). Eduard Fiedler is the author of the Czech monograph The Self-Giving of Christ: Christological Foundations of Klaus Hemmerle’s Trinitarian Ontology (Mervart, 2022), editor of the special issue of AUC Theologica on Trinitarian ontology and co-editor of the inaugural volume Trinitarian Ontologies: Towards a Trinitarian Transformation of Philosophy of the new Verlag Karl Alber series Studies on Triadic Ontology and Trinitarian Philosophy. He is also the author of the new German book Kinder der Trinität: Eine trinitarische Ontologie des metaphysischen Kindseins. Eduard Fiedler expressed the heart of his research in Trinitarian ontologies for the Genealogies of Modernity project. He recently gave an interview to the Czech magazine Vědavýzkum.cz (Science and Research) on the transdisciplinary significance of the Trinitarian mystery.

Eduard Fiedler serves as the Coordinator of all TRIERTIUM research group’s activities. His research focuses on Trinitarian ontology and metaphysics, particularly as exemplified in the works of Augustine, Comenius, Ferdinand Ulrich, Klaus Hemmerle, and Kurt Gödel, with the aim of exploring the enigmatic nature of relations, self-referentiality, and self-giving as a precondition for formulating a new Christian synthesis of wisdom and arts in the 21st century.

Cyril Dunaj studied Philosophy at the Pontifical Salesian University in Rome, the Catholic University of Lyon, and the Sophia University Institute in Loppiano, Italy. In 2021, he completed his Ph.D. studies at the Catholic University of Lyon and the Sophia University Institute in Loppiano, focusing on the relationship between reciprocity and ontology in the work of the French personalist Maurice Nédoncelle. He previously served as an Assistant at the Faculty of Theology of the Catholic University of Lyon, teaching a course on Faith and Reason in Modernity. His research concerns the question of intersubjectivity in French personalism, with a particular emphasis on the thought of Mounier and Nédoncelle. Since 2021, he has been a member of the scientific secretariat of the editorial board of the “Dynamic Dictionary of Trinitarian Ontology”, published in Italy. He is also the author of the French book Penser la relation avec Emmanuel Mounier (Parole et Silence, 2019).

Within TRIERTIUM, Cyril Dunaj builds on his previous work on Mounier and Nédoncelle, and develops the question of intersubjectivity and reciprocity in the horizon of Trinitarian ontology, where reciprocity is not a result of relationality but its condition and source. He also explores how Trinitarian relationality can resolve various contradictions in thinking and being when reciprocity becomes the criterion of “new thinking”.

Maurizio Maria Malimpensa received his PhD in Philosophy from the University of Padua in 2021. He has subsequently held research positions at the Faculty of Protestant Theology of the University of Vienna, the Department of Humanities at the University of Ferrara, and the Italian Institute for Historical Studies in Naples. His research focuses on Classical German Philosophy—especially the thought of Johann Gottlieb Fichte—and on modern and contemporary Italian philosophy. He is particularly interested in the systematic foundation of philosophy as a science and its intersections with theology, intersubjectivity, and aesthetics. He is co-editor of the new critical edition of Fichte’s Neue Darstellung der Wissenschaftslehre oder die sogenannte Wissenschaftslehre nova methodo (frommann-holzboog, 2025), and a member of various research networks, including the Associazione Trialogo, the Laboratorio di Filosofia Trascendentale e Fenomenologia, and the Internationale Johann Gottlieb Fichte-Gesellschaft.

Within TRIERTIUM, Maurizio aims to systematically explore the theological and speculative significance of the category of image (Bild) in Fichte’s philosophy in light of a Trinitarian ontology, while also tracing affinities between Fichte’s elaboration of this theme and key moments in Christian thought from the Patristic era to early modernity.

Joseph McMeans received his PhD philosophy at St. Patrick’s Pontifical University in Maynooth, Ireland (2024). His research revolves around the intersection of phenomenology, or Continental philosophy of religion, and the Byzantine philosophical tradition. For his doctoral studies, Joseph offered a focused study on Christos Yannaras’ response to Martin Heidegger’s onto-theological critique of metaphysics, which seeks to promote the trinitarian philosophy of the Greek Church Fathers as an adequate means of overcoming the impasse of post-Nietzschean nihilism. He is the co-editor of Finitude’s Wounded Praise: Responses to Jean-Louis Chrétien (Eugene, OR: Wipf&Stock Publishers, 2023).

Within TRIERTIUM, Joseph continues his work on the Greek Church Fathers’ philosophical tradition, with special attention given to their unique epistemology, or theory of knowledge, that developed in tandem with their trinitarian ontology.

Petr Macek studied History and Theology at Charles University, Prague, and graduated here with a degree in European Studies. In 2018, he finished his Ph.D. studies at the Catholic Theological Faculty, Charles University with the doctoral thesis focusing on the life and work of Metoděj Habáň. Currently, he is a faculty member at the Department of Studies in Culture and Religion, University of Hradec Králové. His research revolves around the intersection of modern Czech church history, philosophy, and theology, with a particular focus on topics related to Catholic social thinking and its theological and philosophical foundations. Petr Macek participated in the “Trinitarian Ontology of the Human Person” project at the Catholic Theological Faculty, Charles University, exploring the social and political dimensions of Trinitarian ontology.

Within TRIERTIUM, Petr Macek continues his research into the social dimension of relational ontology in both the historical and genealogical aspects of this subject, particularly within the context of Czech theological thinking. He also engages in systematic treatment of the given subject, examining the contemporary theological critique of liberalism from the perspective of a metaphysically grounded ontology of peace and community, and its potential contribution to the discussion on the crisis of liberal democracy.

Dalimil Ševčík studied Aesthetics in Brno at the Masaryk University and Philosophy in Olomouc at the Palacký University, as well as the Piano Interpretation at the Janáček Academy of Performing Arts. His master’s thesis was published as the monograph “The Tragic and Antigone in the Work of Søren Kierkegaard” in 2021. Currently, he is continuing his Ph.D. studies in Aesthetics at Masaryk University, focusing on the tradition of the philosophy of music, interpreting it as “musica”, encompassing not only tones and sounds but also the structures and harmonies of the universe and the human soul, including “analogia Trinitatis”.

Within TRIERTIUM, Dalimil Ševčík explores the Trinitarian character of aesthetic relations implied in music in its broader sense. Subsequently, he seeks to establish a dialogue between the older tradition of Trinitarian metaphysics of music and selected approaches in modern philosophy.
