About

My name is Christos-Alexandros Psomas ( I go by Alexandros or Alex ). I am a postdoctoral researcher in the Computer Science Department at Carnegie Mellon University, hosted by Ariel Procaccia. My research focuses on the intersection of Computer Science and Economics. I apply tools and insights from computer science to study problems in a variety of economic environments. I am broadly interested in algorithmic economics, artificial intelligence, computational social choice and mechanism design, machine learning, as well as algorithmic game theory and theoretical computer science in general.

I completed my PhD in May 2017 in the Theory of Computation group at UC Berkeley, where I was extremely fortunate to be advised by Christos Papadimitriou. I have worked as an intern in Microsoft Research in Redmond, WA, during summer 2015, with Nikhil Devanur. I also spent summers 2013 and 2014 in the International Computer Science Institute in Berkeley, CA, under the supervision of Eric Friedman.

I am on the academic job market this year.
