Hello, I am Panayiotis and welcome to my personal webpage!

I obtained my BSc and MSc degree from the National and Kapodistrian University of Athens (NKUA) where I was also a member of the Management of Data and Information Knowledge Group (MaDgIK).

Currently, I am a Doctoral Assistant at the École Polytechnique Fédérale de Lausanne (EPFL), affiliated with the Distributed Information Systems Laboratory (DIS Lab).

My research interests span the overlapping areas of Data Analysis, Machine Learning, Semantic Web, Databases as well as Distributed Systems and Artificial Intelligence.
