Dr. Klitos Christodoulou is an Assistant Professor in the Department of Digital Innovation at the University of Nicosia (UNIC). He is also the Research Manager at the Institute For the Future (IFF) and the Scientific Lab leader of the Distributed Ledgers Research Center (DLRC) at IFF (https://www.unic.ac.cy/iff/dlrc/). A Center that aims towards fostering academic research on blockchains. He holds a B.Sc. in Computer Science and an M.Sc. in Advanced Computer Science – with specialisation in Advanced Applications, both from the University of Manchester, UK. In 2014, Klitos obtained his Ph.D. in Computer Science from the School of Computer Science at the University of Manchester, UK. He has been an adjunct staff member of the Information Management Group (IMG) in the School of Computer Science, at the University of Manchester where he engaged in various research and teaching activities. His research interests span both Data Management challenges; with a focus on Machine Learning techniques, and Distributed Ledger Technologies; with an emphasis on Blockchain ledgers. Klitos teaches courses on Blockchain Applications and Blockchain Programming under UNIC’s MSc in Digital Currency programme. He is also a member of the ISO/TC 307 Blockchain and Distributed Ledger Technologies group. Klitos is also an active member for developing the Cyprus National Strategy for Blockchain. Currently, representing Cyprus as an invited expert at the European Blockchain Partnership.
