Last Update

April, 2015.

Welcome!

I obtained my PhD in Text Mining at the Department of Informatics, Athens University of Economics and Business, under the supervision of Associate Professor Michalis Vazirgiannis, during May 2009. My PhD Thesis is titled: “Word Sense Disambiguation and Text Relatedness based on Word Thesauri”. Currently, I am a Senior Researcher at the Biotechnology Center of the Technical University of Dresden, working in Text Mining for Bioinformatics, co-operating with Prof. Dr. Michael Schroeder. Previously, I was a Post Doc Fellow, at the Department of Computer and Information Science, Database Systems Group, Norwegian University of Science and Technology, cooperating with Prof. Kjetil Nørvåg. I am also member of the DB-NET Team on Data and Web Mining since 2002.

Before my PhD at AUEB, I was at Imperial College where I obtained my MSc degree in Advanced Computing at the Department of Computing, and before that I was in AUEB again, where I obtained my BSc in Informatics from the respective department. In the publications area you can find my MSc Thesis:“ATLANTIS: A Layered Architecture for Web Content Post Retrieval Analysis”.

Research Interests
My research interests include bioinformatics, word sense disambiguation, text retrieval, classification, and clustering, statistical natural language processing techniques, measures of lexical semantic relatedness and similarity, semantic smoothing kernels, supervised and unsupervised techniques for embedding knowledge resources in text applications, ontologies, construction and processing of semantic graphs, semantic information extraction from text, and digital libraries. I am always in search for new text and data mining applications in Bioinformatics. If you have any interesting ideas feel free to contact me. In the download area you can find interesting resources, as well as software I have developed during my research. You may want to check out the Omiotis measure of semantic relatedness for pairs of senses, terms, and in general text segments. You may also want to read about the THESUS system, on which a part of Omiotis was based.

Collaborations
I have developed collaborations with the Department of Informatics and Telematics, Harokopio University of Athens (Dr. Iraklis Varlamis), the Institute of Informatics and Telecommunications, of the Greek National Centre for Scientific Research "Demokritos" (Dr. George Paliouras), the Natural Language Processing Group of the Deparmtent of Informatics, at AUEB (Assistant Professor Ion Androutsopoulos), and the Department of Computer and Information Science, Database Systems Group, Norwegian University of Science and Technology (Prof. Kjetil Nørvåg). Finally, I am a member of the Hellenic Artificial Intelligence Society.

Visiting Researcher
I was a visiting researcher in March 2007, and March 2011, at the Department of Computer and Information Science in NTNU, located at Trondheim, Norway, thanks to Professor Kjetil Nørvåg.

More information about several of these past projects can be found here.

Teaching
In the past, I have offered more than 150 hours of Teaching Assistance (TA), as well as lecturing services, for the Department of Informatics, AUEB (October 2003 until January 2009), for the Department of Computer and Information Science, NTNU (May 2009 - March 2010), and the Department of Informatics, TUD (March 2010 - present). The courses in which I can offer services, among others, include data mining, text mining, databases, artificial intelligence, natural language processing, information retrieval, knowledge discovery and management, semantic search, and programming languages (C, C++, Java), both in the undergraduate (e.g., BSc) and the graduate levels (e.g., MSc).

Traveling
As most people do, I like travelling abroad. Every journey is a valuable experience. Please visit my photos area and have a look at some interesting places I have been to.
