My name is Caspar Oesterheld (anglicized pronunciation). I am currently a Computer Science PhD student at Duke University but will move to Carnegie Mellon University for spring 2022. I am supervised by Vincent Conitzer. My interests lie at the intersection of game and decision theory as well as artifial intelligence and theoretical computer science.
