About

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, machine learning, computational social choice and mechanism design, as well as algorithmic game theory and theoretical computer science in general. I am very interested in projects that involve both theory and real-world applications. Examples include collaborations with non-profit organizations such as 412 Food Rescue and the Indy Hunger Network.

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.

My research is funded by an award from the Herbert Simon Family Foundation, a Google Research Scholar Award, a Google AI for Social Good award, a MEGA-ACE grant from the Algorand Foundation, and the NSF CAREER Award.
