Fairness and Incentives: From Theory to Practice
In this talk, I will discuss some of my work on fair division in dynamic environments, motivated by collaborations with food-rescue organizations. In these settings, resources arrive over time and must be allocated immediately, often with incomplete information and competing objectives such as fairness to recipients and convenience for drivers. I will show how these practical constraints motivate new theoretical questions in online fair division, discrepancy theory, and mechanism design, and how the resulting theory can, in turn, inform the design of deployed systems.

Alexandros Psomas is an Assistant Professor of Computer Science at Purdue University. His research is in theoretical computer science, especially algorithmic game theory, mechanism design, fair division, auctions, and problems at the intersection of computer science and economics. His work also connects theory to practice through applications such as fair and efficient food allocation. He is also a Visiting Faculty Researcher at Google Research. Before joining Purdue, he was a Research Fellow at the Simons Institute for the Theory of Computing and a postdoctoral fellow at Carnegie Mellon University, hosted by Ariel Procaccia. He received his Ph.D. from UC Berkeley in 2017 under the supervision of Christos Papadimitriou. He is the recipient of an NSF CAREER Award, a Google AI for Social Good Award, and a Google Research Scholar Award.
