Overview

Broadly speaking, we study computational processes involved in human language with particular attention to semantics. Much of our current work has focused on the meaning of quantification in natural language, logical reasoning, and explaining cross-linguistic similarities between languages. In our research, we have paid particular attention to how various complexity measures can help us understand the difficulty of core cognitive abilities, such as language learning, comprehension, or reasoning. Our approach is characterized by a mixture of formal (logic, computational modeling, simulations) and empirical (neurobehavioral experiments, corpus linguistics) methods. It draws inspiration from methods and concepts in theoretical computer science, e.g., formal language theory, computational complexity theory, logic, machine learning, and information theory. The underlying goal is to understand human cognition better from various theoretical angles and contribute to the mathematically and computationally rigorous theories of language and cognition.

Research directions

Our current research focuses on three main lines: 

  1. Computational explanations of semantic universal across languages
  2. Psycholinguistic research on the meaning representations and their variability 
  3. Studying reasoning abilities of humans and artificial neural networks
