Personal profile
Research Interests
My research lies in the intersection of theoretical computer science and artificial intelligence, with an emphasis on algorithms and computational complexity. In particular, I am interested in problems related to social choice theory, fair division, competitive markets, game theory and mechanism design.
Qualifications
BSc in Computer Science, University of Patras, 2009.
MSc in Computer Science, University of Patras, 2011.
PhD in Computer Science, Aarhus University, 2015.
Biography
I am a Lecturer in Algorithms and Complexity at the University of Edinburgh. Before then, I was a Lecturer in Computer Science at the University of Liverpool. I obtained my PhD degree from the Computer Science Department of Aarhus University, Denmark in 2015, under the supervision of Peter Bro Miltersen. In the past, I was a postdoctoral researcher at École polytechnique fédérale de Lausanne, and before that, I was a postdoctoral research assistant at the University of Oxford. My MSc advisor was Ioannis Caragiannis.
