Agostina Pirrello

Agostina Pirrello is a PhD Candidate in EU and International Law at the Law Department of Utrecht University, where she works in the Utrecht Centre for Regulation and Enforcement in Europe (RENFORCE). Her research aims at investigating empirically how access to justice can be enhanced in the light of the emerging supranational governance of migration.  Agostina started her journey into academic research at the Forschung Platform Religion and Transformation, where she worked with Professor Stefan Hammer as a Research trainee. During her time in Vienna she polished the research she conducted for her master thesis in Comparative constitutionalism. She analyzed the legal challenges that the EU has to face due to religious multiculturalism through the lenses of the process of "westernization" described by the french philosopher Serge Latouche.    Agostina's current interest includes the impact of EU Agencies on migrants' fundamental rights, the guarantees ensured by the right to an effective remedy and its relationship with elements of good administration.   Prior to academia, Agostina gained valuable professional experience in the field of migration by working at the Italian Ministry of Interior (Territorial Commission for International Protection of Bologna) and at the European Union Agency for Asylum (EUAA) in Malta. She had also previously completed her vocational training at the European Commission, in the Visa Policy Unit of the DG Home Affairs.

Giovanni Scattolin

Giovanni Scattolin holds a Master's degree in Philosophy from the University of Trento. His main research interests are the philosophy of Hegel and German Idealism, with special reference to the doctrine of identity and otherness in the science of logic. He worked on this topic at the Research Centre under the direction of Prof. Kurt Appel. Another of his main areas of work is the question of Hegel's relationship to Greek philosophy: his Master's thesis linked these two aspects, with a focus on the Hegelian interpretation of Plato's Parmenides.

Clarissa Breu

Clarissa Breu is a research assistant at the New Testament Seminar of the University of Göttingen. After a dissertation on postmodern theories of authorship and the Revelation of John ("Autorschaft in der Johannesoffenbarung", Tübingen 2020) at the University of Vienna, she is now working on a connection between performative gesture theories and the Gospel of John. Her approach to New Testament texts is characterised by a focus on cultural studies questions and theories. Her article "Female Seed as a Metaphor" (JSNT 45/2022) was awarded the "Bernadette J.

Mattia Vicentini

Mattia Vicentini is a doctoral student in Theology at the Pontifical Gregorian University with a research project entitled "Sacramentality as a form of a hermeneutic of history". He has a master's degree in Philosophy at the Università degli Studi di Trento, a master's degree in Philosophy at the TU Dresden as well as in Fundamental Theology at the Pontifical Gregorian University. He is currently at the research centre RaT in order to do research for his doctoral project.


His research is a fundamental theological work within the context of the theology of history starting from some of its aporias. By taking into consideration some classic categories of reflection, he wants to re-elaborate them in a historical-hermeneutic key with particular attention to their practicability. The field of the reworked questions is identified as sacramentality. It is sacramentality, thanks to its theoretical and practical, concrete and transcendental being, a unitary dimension of the human and the divine, that represents the religious fact in history.


A particular attention is paid to the method, which is intimately connected to the purpose of the work. The primary bibliography has a interdisciplinary character. Among others, Maurice Blondel, Pierre Bourdieu, Henri-Irénée Marrou and Chrisptoph Theobald are considered.

Francesco Porchia

Francesco Porchia is a PhD student in Ethics of Communication, Scientific Research and Technological Innovation at the University of Perugia and is currently a Visiting Research Fellow at the University of Vienna.

In his research project, he investigates the theme of existence starting from F.W.J. Schelling, dwelling on the concepts of life and death in the Philosophie der Offenbarung: these concepts are not contradictory, but can be useful for rediscovering the relationship between the human being and the foundation.

According to this approach, death does not only constitute the end of life, and so it is not possible to consider life as a determination of the individual's will to dominate the world.

Through the concept of revelation, the most personal act of God, it is possible to rediscover a new sense of these concepts in which death is understood as a possibility and in which life is re-evaluated thanks to the reflections conducted on the relationship between the human being and the foundation. The research aims to propose possible contributions to an ethics of communication from a theoretically oriented perspective. Thus, starting from the search for God as a person, the common personal side of human beings can be rediscovered.

Lorenzo Ruggerini

Lorenzo Ruggerini wrote his Master Thesis in cooperation with RaT. He examined the theological aesthetic developed by Hans Urs von Balthasar (1905-1988). See his abstract below:

Title: The beauty in the world: a philosophical reading of H.U. von Balthasar's Aesthetic Theology


In this thesis I carry out a philosophical reconsideration of the theological aesthetic developed by Hans Urs von Balthasar (1905-1988) concerning the form and the matter of the divine Being’s disclosure in transcendental beauty.

Hence, It delves deeply into the meaning of the trinitary expression as a complete and eternal form of expression of each divine Person towards the others, of creatural beauty as a limited but beautiful image grounded on God’s infinite transcendence and of Jesus Christ as concreta analogia entis. This allows to further examine the Balthasarian characterization of the creatural nature as limited, determined and incidental in such a way that will become problematic in the light of the philosophical reconsideration of the phenomenon of beauty. Subsequently I argue the philosophical inability to observe in the worldly realm of being the distinction between existence and essence and, hence, the difference between limited creatural being and unlimited divine Being abridged by the analogia entis formulation.

Dr. Nataliia Reva


Dr. Reva obtained her PhD in Philosophy from the Taras Shevchenko National University of Kyiv in 2021. Her doctoral research focused on the intersection between the philosophy of logic and cognitive science. Dr. Reva was awarded a JESH Scholarship by the Austrian Academy of Science and spent July and August 2022 as a Visiting Researcher at our research centre RaT.

In her current research she focusses on the topic of “Evil and Suffering in the World” with specific attention to the concept of the embodiment of evil and how to find resilient strategies in coping with it. She proposes to study evil not as an abstract philosophical concept, but as a real-life threat that can we be felt and therefore studied empirically. The areas of her research interests are philosophy of religion, informal logic, critical thinking, experimental philosophy and cognitive science.
