Nikolaos Pappas

Associate Professor, Docent

Dr. Pappas performs research on semantic wireless communications, age of information, stochastic modelling and performance analysis of communication networks, and wireless energy harvesting networks.

Presentation

Nikolaos Pappas received the B.Sc. degree in computer science, the B.Sc. degree in mathematics, the M.Sc. degree in computer science, and the Ph.D. degree in computer science from the University of Crete, Greece, in 2005, 2012, 2007, and 2012, respectively.

From 2005 to 2012, he was a graduate Research Assistant with the Telecommunications and Networks Laboratory, Institute of Computer Science, Foundation for Research and Technology, Hellas, and a Visiting Scholar with the Institute of Systems Research, University of Maryland at College Park, USA. From 2012 to 2014, he was a Post-Doctoral Researcher with the Department of Telecommunications, Supélec, France. From March 2014 to March 2016, he was a Marie Curie Fellow with Linköping University. Currently he is an Associate Professor and Docent at the Division for Database and Information Techniques (ADIT), Department of Computer and Information Science (IDA) where he is leading the Communications for Networked Intelligent Systems Group.

He is serving as Area Editor for the IEEE Open Journal of Communications Society, and Editor for the IEEE Transactions on Machine Learning in Communications and Networking and IEEE/KICS Journal of Communications and Networks. He is serving as an Expert Editor for invited papers for the IEEE Communications Letters. From 2013-2018 he was serving as an Editor for the IEEE Communications Letters. From 2018-2023 he was serving as an Editor for the IEEE Transactions on Communications. He is serving as a Guest editor/Leading guest editor in several IEEE Journals and Magazines.

Nikolaos Pappas appeared in the Top 2% scientists list, single year impact for 2020-2023, in the area of Networking and Telecommunications.
