I received my BSc, MSc and PhD degrees from the Department of Computer Science and Engineering of the University of Ioannina in 2005, 2008 and 2014 respectively. I'm member of the Systems Research Group. My main research interests lie in the fields of search engines, distributed file systems and scalable datastores, including anything involving "Big Data".
