Dimitrios Karapiperis

Dimitrios is an academic associate at the School of Science and Technology at IHU. His esearch interests lie mainly in the field of Entity Resolution (Record Linkage) and Privacy-Preserving Record Linkage, where I focus on developing similarity algorithms, data structures, approximation schemes, and scalable (distributed) solutions that rely on various randomization schemes. Prior to joining IHU, Dimitrios was a post-doctoral associate at the Hellenic Open University. Dimitrios received a PhD and an MSc from the Hellenic Open University and from the University of York (UK), respectively. His doctoral thesis was included in the IEEE Intelligent Informatics Bulletin of August 2017.
