SHORT CV

Pavlos Efraimidis is an Associate Professor in Algorithms and he is leading the Algorithms and Privacy Research Team of the Programming and Information Processing Lab. He was born in Neuss, Germany, in 1971 and received his PhD in Informatics in 2000 from the University of Patras and the diploma of Computer Engineering and Informatics from the same university in 1995. He joined the Faculty of the Department of Electrical and Computer Engineering of Democritus University in 2003, where he was elected Associate Professor at the end of 2014. As of February 2023 he has been promoted to Professor.

His main work is on algorithms and his current research interests are in the fields of algorithmic game theory and algorithmic aspects of privacy. He has have published over 60 refereed technical papers and book chapters, and participated in over 15 national and European research projects. He has worked for the Computer Technology Institute in Patras (1997-2000) and since 2003 for the Athena Research Center (Adjunct Researcher). His industrial experience includes working as a computer engineer in the high performance computing field (Parsytec Computer GmbH, Aachen, Germany) and in the financial sector (ASYK – Athens Stock Exchange, Athens, Greece).

He has graduated 3 Ph.D students and around 10 MSc students, and he is currently supervising 4 PhD students, 2 MSc theses and about 10 diplom theses. His citations can be found here. He was the head of the division of Software and Applications Development of my department, from March 2015 to November 2017.
