Panagiotis Gavriilidis is currently pursuing a Ph.D. in the Department of Informatics and Telecommunications at the National and Kapodistrian University of Athens, under the supervision of Professor George C. Alexandropoulos. He acquired his integrated Master’s (Hons) degree in Electrical and Computer Engineering from the Aristotle University of Thessaloniki in July 2022. His research focuses on signal processing techniques for extremely large Multiple-Input Multiple-Output (MIMO) systems, with emphasis on metasurface-based antenna architectures. In particular, he is studying their realistic modeling and performance analysis under near-field operation, aiming to understand their physical-layer capabilities and fundamental performance limits for the optimization of Sixth Generation (6G) networks. Within this context, as part of his Ph.D., he is contributing to two European Union Horizon-funded research projects.

As a Fulbright Visiting Research Student, he will spend five months at the Department of Electrical and Computer Engineering at the University of California, San Diego, collaborating with Professor Nuria González Prelcic. His project will explore the time-domain control of Reconfigurable Intelligent Surfaces (RISs) and how this dynamic reconfiguration can shape the frequency response of wireless channels to enable enhanced connectivity and over-the-air computation.
