Dr. Chatzimisios is currently an Associate Professor with the Computing Systems, Security and Networks (CSSN) Research Lab of the Department of Informatics at the Alexander Technological Educational Institute of Thessaloniki. He currenlty participates in several European and National research projects (such as COST Actions, Arximidis III). More specifically, he serves as Deputy Leader for Working Group WP5 "Standardization and dissemination", as Training School Coordinator as well as a Member in the Management Committees of COST Action IC1003 (European Network on Quality of Experience in Multimedia Systems and Services (QUALINET)) and of COST Action IC0905 (Techno-Economic Regulatory Framework for Radio Spectrum Access for Cognitive Radio/Software Defined Radio (TERRA)). Moreover, he is a Substitute Member in the Management Committees of COST Action IC0703 (Data Traffic Monitoring and Analysis: theory, techniques, tools and applications for the future networks) and of COST Action 298 (Participation in the Broadband Society).

Since 2010, Dr. Chatzimisios is serving as Standards Liaison for the Internet & the Communications Systems Integration and Modeling (CSIM) Technical Committees in the IEEE Communication Society (ComSoc) Standards Board and he is very active in several IEEE activities such as handling the Young-Scientist’s-Corner Initiative (i-YSC) and serving as Chapter Associate Editor for the Newsletter of the IEEE Greece Section.

He is also the Departamental Erasmus/Socrates Coordinator, a member of the Practical Training Committee and the Student Branch Counselor of the IEEE Student Chapter of the Department of Informatics (Alexander TEI of Thessaloniki).
