Welcome!                                                                                                   

My name is Eftychia Datsika and I am an experienced researcher in the field of Mobile Telecommunications (LinkedIn, Github, ResearchGate, Scholar).  I work in Greek Public Sector as Computer Science specialist currently involved in IT project management in the ICT department of Municipality of Ioannina, Greece.

Previously, I was a member of Baseband Lab, Huawei Technologies, Sweden and worked as researcher at IQUADRAT Informatica S.L., Spain and Nearby Computing, Spain. My research interests lie in the areas of mobile and wireless network architecture design and performance optimization.

I hold a PhD degree (2018, UPC Best Doctoral thesis award in ICT, 2020) focused on QoS-oriented 5G network resource management from Signal Theory and Communications (TSC) Department, Technical University of Catalonia (UPC), Spain, an MSc degree (2012) with thesis focused on wireless sensor network cross-layer optimization and a BSc degree (2010) in Computer Science, University of Ioannina, Greece.

I have gained significant teaching experience working as an instructor of Informatics related courses in various public institutions in Greece. I also hold a Pedagogical Proficiency certificate (ASPETE, 2014).
