I am an associate professor in logic and cognitive modeling at the Institute for Logic, Language and Computation at the University of Amsterdam. I am affiliated with the Faculty of Humanities within the Research Priority Area Brain & Cognition. My research interests include logic, cognitive science, formal semantics, complexity theory, philosophy, and any combination of these. I try to use logical and computational tools for cognitive modeling and designing psychological experiments. In my current research, I'm mostly concerned with the logic and cognitive science of language and social interactions. I have been especially interested in computational and cognitive aspects of quantifier meaning. In January 2013 I started my NWO Veni project `What makes social interactions hard? A computational study of intentions, knowledge, and beliefs.'
I studied philosophy, psychology, mathematics, and linguistics at the Individual Studies in the Humanities (MISH), University of Warsaw, where I obtained MA in the area of logic at the Institute of Philosophy. Then I went to Amsterdam and defended PhD at the Institute for Logic, Language and Computation. My advisors were Johan van Benthem, Marcin Mostowski, and Theo Janssen. I was working in the `Games and Linguistics' part of the GLoRiClass project funded by the European Community in the Marie Curie Program. My thesis work was about computational complexity and generalized quantifier theory. Directly after the graduation I was briefly teaching at the Cognitive Artificial Intelligence Program, Utrecht University and consulting for company SpeechConcept in machine translation. Next, I got a post-doctoral grant to work in the Department of Philosophy, Stockholm University. My project funded by the Swedish Research Council was devoted to language comprehension. I was involved in an experimental work, computational modeling and philosophical analysis in a collaboration with Peter Pagin. From Sweden, I went back to the Netherlands to join Rineke Verbrugge's NWO Vici project 'Cognitive systems in interaction: Logical and computational models of higher-order social cognition' in the the Institute of Artificial Intelligence and Cognitive Engineering of the University of Groningen. In the project I have developed an interest in the cognitive and computational constraints on social interaction.
