My main research interests lie in philosophy of science, philosophical logic, argumentation theory and applied ethics. As regards philosophy of science, I am particularly gripped by methodological problems of specific sciences (e.g. economics, climate science), the limits of our scientific foreknowledge, appropriate ways for expressing and communicating uncertainties, and the role of science in democratic societies. The theory of dialectical structures represents my major research project in philosophical logic and argumentation theory. It can be applied, for example, to reconstruct classical philosophical texts, scientific controversies or societal debates alike. Currently, I'm studying traditional problems in philosophy of science from an argumentation-theoretic perspective (cf. my recent publications); I envisage the detailed reconstruction and argumentative analysis of scientific debates (in terms of the theory of dialectical structures) as a future research project.
