Positions and Education 

I hold an Eleonore-Trefftz Visiting Professorship at the TU Dresden and I am a research fellow at the Department of Philosophy of the University of Cologne. Before coming to Dresden and Cologne, I spent time at Universities in Salzburg, Leuven, Berkeley, Konstanz, Munich, Duisburg-Essen, and Boston. I completed my doctoral studies (Philosophy) at the University of Konstanz and I received my MA (Philosophy) from the University of Salzburg.

Research Topics

My past, current, and future research focus on debates in epistemology, general philosophy of science, metaphilosophy, and philosophy of logic. In epistemology, my research encompasses epistemic disagreement, epistemic pluralism, epistemic normativity, theories of justification, of evidential support and higher-order evidence, and the relationship between logic and reasoning. In the philosophy of science, my research centers on the aims of inquiry, the relationship between confirmation and rationality, and the relationship between explanation and understanding. In metaphilosophy, I am mainly interested in methods of conceptual clarification and conceptual engineering, and on the role of formal methods and idealizations in philosophy.

Besides epistemology, the philosophy of science, and metaphilosophy, I have interests in the history of analytic philosophy, decision theory, and metaethics.

You can find some of my papers here, here, and there.

The picture shows the main plaza of San Ignacio de Velasco in Santa Cruz, Bolivia. San Ignacio is a beautiful, tropical, and vivid city, which is very close to the Brazilian border. Whenever I can, I spend time in Santa Cruz, where I have a huge, wonderful family, and where nature is relaxing and impressively beautiful.
