Dr. Loukides is a Lecturer (Assistant Professor) in the Department of Informatics, King's College London. He was a Royal Academy of Engineering Research Fellow (2011-2016) at School of Computer Science & Informatics, Cardiff University and a Postdoctoral Research Fellow (2008-2011) at the Department of Biomedical Informatics, Vanderbilt University, USA.  His research  interests lie broadly in the field  of  data  mining 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,  as a PC member of conferences (e.g., ICDM and IJCAI), and as a reviewer for journals (e.g., ACM Trans. on Privacy and Security, IEEE Trans. on Knowl. and Data Engin., and J. of Biomed. Inf.). He is editor of Medical Data Privacy Handbook and author of Anonymization of Electronic Medical Records to Support Clinical Analysis
