| | | | | | Welcome to my personal homepage. Currently I live in Los Angeles. I am a Ph.D. student at the Department of Computer Science, Viterbi School of Engineering, University of Southern California. I am a member of the Information Integration Group, Intelligent Systems Division-Information Sciences Institute (ISI) at Marina Del Rey, CA. As well, I collaborate with the Information Systems Laboratory, Institute of Computer Science, Foundation for Research and Technology-Hellas (a.k.a. ICS-FORTH), Heraklion/Crete, Greece. | | | | |
Research Interests | | | | Key Interests: Data Integration, A.I. Knowledge Representation and Reasoning, Description Logics, The Semantic Web and A.I. applications on it, Ontology Reasoning, Ontology Evolution, Logic, Databases, Action Theories, Information Retrieval, Distributed Systems.
Summary of Interests: I am currently working on data integration, and more specifically on Local-As-View query rewriting (also known as query answering using views). Before coming to USC I was an R&D engineer at ICS-FORTH, where I also was a research assistant during my M.Sc. studies. While at FORTH, I was working on the Semantic Web, which I find extremely intriguing. In particular, I studied Artificial Intelligence applications (namely belief revision) upon RDF/S ontologies. I am very interested in Knowledge Representation and Reasoning while former work of mine (my B.Sc. thesis) dealt with action theories. My other interests include Information Retrieval and other Database areas. During my M.Sc. studies in Crete, I chose distributed and parallel systems, as a minor. I worked on projects in the following areas: Distributed Systems, Wireless Networks, Mobile Computing, P2P Systems, and Web Technologies. Most of these works were under close collaboration with several ICS-FORTH laboratories.
| | Bio | | | | I was born in Esslingen, Germany, in April of 1982. I grew up in Kozani, a city in northern Greece, where I went to public elementary and secondary schools. In 1998 I moved to Stuttgart Germany. I finished the Greek Lyzeum (high-school) of Stuttgart in 2000. In fall 2000 I started studying computer science at the Computer Science Department, University of Crete, Greece. After I had completed my studies with a Bachelor`s and a Master`s degree I worked at ICS-FORTH, for six months. In August 2008, I came to University of Southern California. After two years I graduated from USC with a Master of Science. Now I'm a Ph.D. student under the supervision of Jose Luis Ambite. My c.v. can be found here.
