Maria Halkidi is currently Associate Professor at the Department of Digital Systems, University of Piraeus. She obtained her degree in Informatics from University of Piraeus in 1997 and her M.Sc. and PhD degrees from Athens University of Economics & Business (AUEB) in 1999 and 2003, respectively. She has conducted research in AUEB participating in several National and European-funded projects and in University of California at Riverside as a Marie-Curie fellow funded by EU. Her research interests include Learning and Data Mining Techniques, Data Mining in Distributed environments (P2P systems, Sensor networks), WWW & Databases (web documents clustering, web content management). She has also participated in many program committees of international conferences in the areas of Data Mining and Machine Learning. She is member of IEEE and ACM.
