Dr. Loukides is a Lecturer (Assistant Professor) in the School of Computer Science & Informatics, Cardiff University, and a Royal Academy of Engineering Research Fellow. Before joining Cardiff University, he was a Postdoctoral Research Fellow at the Department of Biomedical Informatics, Vanderbilt University.  He holds a  PhD in Computer Science from Cardiff University and a Diploma  in Computer Science from University of Crete, Greece.  His research  interests lie broadly in the field  of  data  management with  a focus on privacy. His recent research investigates theoretical and  practical aspects of  data privacy, including algorithmic  design, optimization, and formal  modeling, and explores  applications  in  healthcare and  business. He serves  in the  Editorial Board  of Journal of Health Informatics and the program  committees of conferences  and workshops, including ICDM, EDBT PAIS, and PriSMO. Dr. Loukides was a Guest Editor for the Informatics Methods in Medical Privacy special issue of Journal of Biomedical Informatics (JBI) and an organizer of the 4th IEEE Workshop on Privacy Aspects of Data Mining (PADM), which was held in conjuction with ICDM 2013.
