Dr Photios A. Stavrou

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 2016. From November of 2016 to October of 2017, he was a Postdoc at the Department of Electronic Systems at Aalborg University in Denmark . As of November of 2017, he is a Postdoc at the Department of Information Sciences and Engineering at KTH Royal Institute of Technology in Sweden .

His main research interests target the design and analysis of wireless networked control systems. The study of such systems necessitates the interplay between dynamical systems and their communication aspects. Toward this end, his research can be characterized as interdisciplinary because it combines tools from control and estimation theories, communications, and convex optimization. Specifically, his research spans the following areas:

  • Properties of information measures in systems with memory and feedback like for example, functional properties of directed information and conditional directed information and their utility in investigating the extremums of feedback capacity and causal rate distortion.
  • Causal and Zero-Delay processing of information in systems with feedback. For example, the fundamental limits of causal rate distortion theory in systems with memory.
  • Low-delay joint source-channel coding. For example, the joint source-channel coding between a source with memory and a channel with feedback and their distortion-cost trade-offs.
  • Feedback capacity in communications. For example, the necessary and sufficient conditions for deriving closed form expressions of unknown channels with memory and feedback.
  • Communication for control. For example, quantization and rate performance of unstable sources with memory in closed loop systems.
