Research Projects
Efficient data management for scientific applications (2008-now)
Ecole Polytechnique Federale de Lausanne
(2007 Award for prof. A. Ailamaki, European Young Investigator Awards)
Postdoctoral researcher
Several scientific applications are constrained by the complexity of manipulating massive datasets. Observation-based sciences, such as astronomy, face immense data placement problems, whereas simulation-based sciences, such as earthquake modelling, must deal with complexity. Efficient data management by means of automated data placement and computational support can push the frontiers of scientists' ability to explore and understand massive scientific datasets.
Hyperion Project (2002-now)
University of Toronto
Graduate and post-graduate researcher
?e Hyperion Project focuses on research about the principles and control of information sharing in a P2P database system. In such a system data are structured and queries complex.

Data management for location-based services of mobile nodes (2005-2008)
??ба2003 03?291 Ministry of Development - General Secretariat of Research and Technology, Greece
PhD student
The project aims at the study and development of techniques for the efficient information management that depend on the position of mobile nodes, like humans or vehicles (location-based services). The techniques guarantee the management of enormous volumes of spatio-temporal and topic-based data that are collected and shared through networks, as well as the online service of multiple user requests.
Management of the semantic web: models and algorithms for the processing of semantic content (2004-2006)
Pythagoras: Reinforcement of research teams in universities - Greek Ministry of Education
PhD student
The semantic web suffers from the lack of structure, semantics and meta-information. These are the obstacles of efficient web information search. Current solutions use hierarchicalschemas that tag the available data semantically . The goal of this project is to model and manamge hierarchical schema, offer query processing on such schemas and guarantee the autonomy and distributedness of them.
