I was a postdoctoral researcher at the Database and Information Management group at the Technical University of Berlin. I received my Ph.D. from Aalborg University, Denmark in 2011. During my Ph.D. studies I visited the University of Maryland, College Park, and interned at Microsoft Research, Redmond. In 2007, I graduated from the National Technical University of Athens, Greece. My research interests include cloud data management, query optimization, statistical modeling of data, and adaptive access methods.
