Andrés Cristi

I am a fourth year PhD student at Universidad de Chile and I am fortunate to be advised by José Correa and Paul Dütting. Previously, I received a master's degree in Operations Management from Universidad de Chile.

My interests are focused on Algorithmic Game Theory, specially in Mechanism Design. I am also interested in Approximation Algorithms.

My research is supported by the Chilean Science Foundation (ANID) and a Facebook Fellowship.
