My name is Caspar Oesterheld (click here for (anglicized) pronunciation). I am a Computer Science PhD student at Carnegie Mellon University, supervised by Vincent Conitzer. My interests lie at the intersection of game and decision theory as well as artificial intelligence and theoretical computer science.
