My name is Alexandros Psomas ( I mostly go by Alex ). I am an Assistant Professor in the Department of Computer Science at Purdue University. 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 a Visiting Researcher in the market algorithms group in Google Research (Mountain View) during the Spring and Summer of 2020. I spent Fall 2019 as a Research Fellow at the Simons Institute for the Theory of Computing. Prior to that I spent two wonderful years (2017-2019) as a postdoctoral researcher in the Computer Science Department at Carnegie Mellon University, hosted by Ariel Procaccia.
