Ewa Orlowska on Relational Methods in Logic and Computer Science.

Joanna Golińska-Pilarek is an assistant professor at the Institute of Philosophy, University of Warsaw. Her research interests are focused on logic and its applications, in particular in philosophy, mathematics, cognitive and computer sciences. Recently, she has been working on logics for qualitative reasoning and their (relational) dual tableaux, non-Fregean logics with identity and equimeaning connectives. She has published in the leading international journals in the field (Annals of Pure and Applied Logic, Logic Journal of IGPL, Fuzzy Sets and Systems, Studia Logica, Mathematical Logic Quarterly, Journal of Philosophical Logic, Notre Dame Journal of Formal Logic). She has also co-authored a comprehensive survey monograph, Dual Tableaux: Foundations, Methodology, Case Studies, published by Springer (2011).

Michał Zawidzki is an assistant professor at the Department of Logic and Methodology of Science, University of Łódź. He obtained his PhD from theUniversity of Łódź in 2013.  His research interests are in the fields of modal logics, hybrid logics, decidability, and computational complexity of non-classical logics, tableau calculi, and applications of logics in modeling human interactions. He is the author of a monograph on deductive systems for standard and non-standard hybrid logics. Between 2013 and 2017 he worked as a research fellow on the project Logics for Qualitative Reasoning under the supervision of Dr. Joanna Golińska-Pilarek.
