Dr. Eyal Tal

Eyal Tal's interests lie mainly in epistemology and normativity. His research focuses on issues regarding what we should believe (or do) in light of information about what we should believe (or do). Currently he is working on the connection between epistemic akrasia, total-evidence views, and the Uniqueness Thesis. He is also interested in epistemic defeat, misleading evidence, and normative antirealism.

Jakob Ohlhorst is currently writing his PhD-thesis on entitlements, beliefs that are not grounded in evidence, and on what role intellectual virtues play for such beliefs. He is also interested in other problems concerning the nature and structure of justification as well as issues on self-knowledge, and the formal semantics of normativity. Before coming to Cologne, Jakob has graduated at the University of St. Andrews & Stirling, and studied at the University of Geneva. 

Lisa Benossi's main research interests lie at the intersection between theoretical philosophy, logic and cognitive science. Currently, she is working on Kant's theory of mathematical cognition, in connection with a logical formalization of Kant's transcendental philosophy and results in cognitive science.

Before joining CONCEPT, she was a master student of logic at the Institute of Logic, Language and Computation in Amsterdam, where she worked on the logical formalization of imagination and pretend play. 

Sofia’s main research interests are in epistemology, the philosophy of language, philosophical methodology, and the philosophy of mind and psychology.

Before joining CONCEPT, Sofia studied at Utrecht University and University College London. 

Francesco Praolini is interested in a variety of issues in epistemology including knowledge first epistemology, the value of knowledge and other epistemic states, epistemic goals, epistemic normative theory, the lottery paradox, and the preface paradox. His interests are not confined to epistemology but extend to philosophy of logic and philosophy of language as well. Before joining CONCEPT, he was a PhD student in philosophy at the Centre for Logic and Philosophy of Science at KU Leuven.
