I received my integrated MsC diploma from the Department of Computer Science & Engineering, University of Ioannina, Greece. For my thesis titled "Development of a Big Spatial Data Management System", I designed and implemented a prototype distributed and parallel data management system using MPI that answers spatial range queries on polygons hybridly, parallelizing jobs in both node and thread levels. I am currently a PhD candidate in the Department of Computer Science and Engineering, University of Ioannina, supervised by Prof. Nikos Mamoulis. My research subjects is complex data management with a big focus on non-point spatial data and raster-based approximations. Additionally, I have focused on designing scalable solutions for big data in-memory management problems.
