Research

Understanding the logical structure of "agency" has long been my main interest. I study rational behavior by looking at how information and inference combine with the logical structure of an agent's preferences, reasons for these, and their dynamic changes. I also believe that rationality unfolds at its most vivid in multi-agent settings, and so I study the formal properties of social relations and social influence as these affect agents' belief formation, changing and convergence of opinions. In particular, I am also fascinated by agents' strategic interactions, and study them in the context of various concrete games. Finally, I am excited about differences and similarities across cultures, comparing patterns of reasoning from a logical and historical point of view. Through my research, I have the privilege of collaborating with colleagues and students from philosophy, mathematics, linguistics, computer science and AI, game theory and economics.
