My research interests cover most of the fundamental issues that arise when multiple self-interested entities, so-called agents, interact. These issues include modeling preferences over uncertain outcomes, analyzing optimal rational behavior, and studying mechanisms that allow agents to aggregate their individual preferences (such as voting or allocation rules). In addition to tools from mathematics and economics, concepts from theoretical computer science and artificial intelligence have turned out to be useful when analyzing such situations. In general, my research focuses on statements that can be proved or disproved using formal methods.
