Members and Guests

Current Members

Currently the group hosts the following researchers:

Dunja Šešelja (permanent student, aka full professor, Wasserstraße 221, office 4/202)

Dunja is working in social epistemology and philosophy of science. She serves as a co-editor in chief of the European Journal for Philosophy of Science. Her research topics include formal modeling of scientific inquiry (with focus on agent-based modeling), scientific disagreements and controversies, pursuit-worthiness of scientific theories, and integrated history and philosophy of science. Find more information on her academia page and her page at TU Eindhoven, where she is employed on 25%.

Christian Straßer (permanent student aka full professor, Wasserstraße 221, office 4/401)

Christian is a professor of Logic in Philosophy and Artificial Intelligence at the Institute for Philosophy II at Ruhr University Bochum. He is specialized in non-monotonic logics, defeasible reasoning, argumentation, deontic and adaptive logics. He is interested in utilizing formal methods (such as logical or computational methods) in philosophy. Beyond logic his research interests spread into the philosophy of science and social epistemology. You find more information on him here.

Prof. Dr. Dr. Cali (Hoomanologist)

The –without doubt– most prominent and cheerful member of the group is the Hoomanologist Cali, specialized for Hooman intelligence and well-known for his books “How to train the hooman. The limitations of the hooman mind.” While working in our group he also got interested in logic, see his latest book “My barks don’t lie. Semantic paradoxes as a trademark of Hooman language.” Yes, we can learn a lot from him …

Soong Yoo (PhD student, Wasserstraße 221, office 4/423)

Should epistemic workers of the world unite? There are some thoughts or decision we would make only when hanging around with friends, colleagues, and strangers. Same for people doing cognitive tasks for their living. Soong is working with agent-based-models in hope to see how computer simulations would predict and suggest a better conveyor belt of knowledge production.
Soong is jointly supervised by Dunja and Christian.

Matteo Michelini (Cotutelle PhD student, TU Eindhoven and Ruhr-University Bochum)

Matteo is a cotutelle PhD student of TU Eindhoven and Ruhr University Bochum. He works with agent-based models in the areas of social epistemology and philosophy of science.
Matteo is jointly supervised by Dunja and Wybo Houkes.

Minkyung Wang (PostDoc, Wasserstraße 221, office 4/403)

Minkyung is a postdoctoral researcher in Logic in Philosophy and ArtificialIntelligence. Her current research focuses on integrating logical and probabilistic reasoning, which is addressed in formal epistemology, social epistemology, and formal argumentation. As a mathematical philosopher, she is keen on using formal methods to solve philosophical problems, particularly those related to epistemology, decision theory, and ethics. Her webpage is here.

Christiane Dahl (admin, Building GA 04/42, Mondays at Wasserstraße 4/402)

Christiane is running the offices of Markus Werning, Kristina Liefke, Dunja, and Christian.

Jessica Krumus
Jessica is a Bachelor student in Philosophy and Biology. She has a special interest in logic and metaphysics. After tutoring for the Logic introductory lecture, she started as a student research assistent for Dunja and Christian.
Tom-Felix Berger

Lisa Michajlova

Lisa is now finishing her Bachelor of Science in Mathematics with minor in Philosophy. She currently works as a student assistant with Christian on Probabilistic Argumentation theory. She studies the Probabilistic Framework by Haenni and investigates argument strength defined for example by Pfeifer. Lisa loves playing sports including table tennis and chess.

Javier Osorio Mancilla, Autonomous University of Madrid: Javier will stay with us from January 15-30. He will give a talk for our MA and PhD students.
Ofer Arieli (Tel Aviv) visited us for a week in May 2023.
Badran Raddaoui (Wasserstraße 221, office 4/403, Associate Professor, Telecom SudParis, Polytechnic Institute of Paris).

Badran is spending his sabbatical as a guest in Bochum.

Leon van der Torre (Luxembourg) and Reka Markovich (Luxembourg) visited us for a week in March 2023.
Martin Justin (Master Student, University of Ljubljana)

Martin is a master’s student of philosophy at University of Ljubljana. As an exchange student at RUB, he is working with Dunja on his thesis about disagreement in scientific communities.

Kees van Berkel (Assistant Prof. TU Vienna)

Kees is a PostDoc in the Reasoning, Rationality & Science group. You find his webpage here. He works on logical methods for normative reasoning. This includes methods from modal logic, nonmotonic logic, proof theory, and formal argumentation. He is working together with Christian on formal explanation of reasoning with normative systems. Kees is furthermore interested in the metaethical principle of `ought implies can’ (both from a philosophical and logical point of view), and the philosophy of practical reasoning.

Daniel Frey (Currenta, Leverkusen)

Daniel frequently collaborates with us on agent-based models. He is equally interested in the implementation side of things (e.g., NetLogo) and the conceptual considerations underlying formal models. His master thesis offers an investigation into Kevin Zollman’s notion of transient diversity.

Badran Raddaoui (Associate Professor, Telecom SudParis, Polytechnic Institute of Paris)

Badran Raddaoui is an associate professor of computer science at the Polytechnic Institute of Paris. His research interests include reasoning under inconsistency and uncertainty, formal models of argumentation, satisfiability and constraints programming. Further topics that he is interested in concerns the application of symbolic AI techniques for data and graph mining.
