Profile
Biography
I am a Senior Lecturer (Associate Professor) at the School of Computer Science and Electronic Engineering (CSEE), 糖心Vlog, UK. Prior to this, I was a Lecturer (Assistant Professor) at the same institution (April 2020 - September 2023) and a postdoctoral researcher at the Department of Computer Science, University of Oxford (October 2018 - March 2020). I obtained my PhD in computer science in September 2018 from the University of Patras, Greece. My research interests lie at the intersection of theoretical computer science, artificial intelligence, and microeconomic theory. I am highly interested in the design and analysis of simple algorithms for fundamental problems in algorithmic game theory and computational social choice.
