I am an Assistant Professor at the Department of Informatics of the Athens University of Economics and Business (AUEB), and and a Lead Researcher at the Archimedes Research Unit of the Athena Research Center. I enjoy working on algorithmic problems lying in the intersection of discrete mathematics, computer science and economics, often related to social choice theory. I have a particular interest in fair division, in algorithmic mechanism design, and in graph sampling.

Before joining AUEB, I was a Senior Lecturer at the School of Mathematics, Statistics and Actuarial Science of the University of Essex. Until 2021 I was also affiliated with the Institute for Logic, Language and Computation of the University of Amsterdam as an associate member of the Computational Social Choice Group led by Ulle Endriss. Before joining Essex, I worked as a postdoctoral researcher at the Sapienza University of Rome, hosted by Stefano Leonardi, and at the Centrum Wiskunde & Informatica (CWI), hosted by Guido Schäfer. I completed my PhD at AUEB, under the supervision of Vangelis Markakis.
