Associate Professor
Email: mhalk at unipi dot gr
I am Associate Professor at the Department of Digital Systems, University of
Piraeus. Also,
I am
member of the Network oriented systems
& services lab and the DataStories
research group.
I obtained my degree in Informatics from University of Piraeus in 1997 and my M.Sc. and PhD degrees from
Athens University of Economics & Business
(AUEB) in 1999 and 2003, respectively.
I have conducted
research in AUEB and CERTH
(Centre for Research & Technology, Hellas) participating in several
National and European-funded projects and in University
of California at Riverside as a Marie-Curie fellow funded by EU.
My research
interests include Machine Learning and Data Mining Techniques,
Recommender Systems, Social Network Analysis, Big Data Analytics, Data Mining
in Distributed environments.
I have participated
in many program committees of international conferences in the areas of Data
Mining and Machine Learning.
