Georgios Piliouras Associate Professor Engineering Systems and Design Singapore University of Technology and Design (SUTD) My main research interests lie in the areas of algorithmic game theory, computational learning theory, multi-agent learning and dynamical systems. I am interested in exploring dynamic phenomena that arise from the interaction of numerous adapting agents. In August of 2010, I received my Ph.D. in Computer Science from Cornell University under the guidance of Éva Tardos. I have been awarded the Singapore NRF Fellowship (2018). Several postdoc and PhD students positions available. Email me with questions/material. I am looking for researchers interested in working on the intersection of algorithmic game theory and dynamical systems (e.g. evolutionary game theory, learning in games, etc). Researchers with background in at least one of these areas who are interested in exploring the other are particularly encouraged to apply. Successful applicants will have the opportunity to collaborate with Prof. Christos Papadimitriou. I am also looking for researchers interested in working on the intersection of game theory and blockchain, bitcoin, ethereum and cryptoeconomics more broadly.
