Photios (Photis) A. Stavrou received his Diploma in Electrical and Computer Engineering from the Department of Electrical and Computer Engineering (ECE), Aristotle University of Thessaloniki (AUTH) in 2008. He was awarded his Ph.D degree in Electrical Engineering from the Department of ECE, University of Cyprus (UCY) in June 2016. From November of 2016 to October 2017, he was a postdoc at the Department of Electronic Systems at Aalborg University in Denmark . From November of 2017 to November of 2021, he was a Postdoc and Researcher in the Division of Information Sciences and Engineering at KTH Royal Institute of Technology in Sweden . From December of 2021 to August of 2022 he was a Senior Researcher and as of September of 2022 he is an Assistant Professor at Eurecom within the Communication Systems Department.
His main research targets the fundamental understanding of a radically new goal-oriented communication paradigm. In other words, his research aims to put into a meaningful mathematical framework the so called semantics of information, i.e., the significance and usefulness of messages with respect to the goal of data exchange and the overall application. He is also interested in understanding the fundamental limitations of networked control systems. The study of those systems is interdisciplinary because it combines tools from control and estimation theories, communication, optimization and numerical analysis.
