Background
I hold an Integrated Master’s degree in Electrical and Computer Engineering from the Aristotle University of Thessaloniki (AUTH), which I completed between September 2018 and July 2023. During my studies, I developed a strong interest in optical communication systems, which led me toward the field of wireless body area networks.
Since September 2023, I have been pursuing a Ph.D. at École Centrale Méditerranée as part of a Marie Skłodowska-Curie Actions (MSCA) project OWIN6G, where my research focuses on optical WBANs. My current work involves designing, modeling, and optimizing optical wireless communication systems for patient monitoring applications, with an emphasis on MAC layer solutions for improved energy consumption, while achieving a certain level of communication reliability.
I am interested in interdisciplinary research and always keen to deepen my understanding of diverse technologies, while contributing to collaborative academic environments.
