Welcome

I am a post-doctoral reseacher at the Department of Computer Science, Aarhus University (AU) working with Associate Prof. Ira Assent and a member of the Data-Intensive Systems group.

My research interests are in data management and query processing with a special focus on complex data types including spatial, temporal and text, and on routing optimization problems.

Prior to my position at AU, I was with the Department of Computer Science, Humboldt-Universität zu Berlin (HUB) working with Prof. Dr. Ulf Leser (2013-2015), the Department of Computer Science, University of Hong Kong (HKU) working with Prof. Nikos Mamoulis (2011-2013) and the Department Informatics and Telecommunications, University of Athens (UoA) working with Associate Prof. Afrodite Tsalgatidou (2005).

I received my PhD degree in 2011 from the National Technical University of Athens (NTUA), Greece. My thesis titled "Evaluating Queries over Route Collections", was supervised by Prof. Timos Sellis and Prof. Yannis Vassiliou.

I received my Diploma degree on Electrical and Computer Engineering in 2003 also from NTUA. My diploma thesis titled "Query Language for Hierarchical Structures" (in greek), was supervised by Prof. Timos Sellis.

My CV (September 27, 2017) is available here.
