Links to my Ranking on ArnetMiner, my Citations on Google Scholar and my full list of publications on DBLP.

I am a post-doctoral researcher and member of the Data Management Lab at the Computer Science Department at Boston University, working with Professor Evimaria Terzi on Data Mining Problems, Customer Review Analytics, Opinion Mining and Social Graphs. I am also a Visiting Fellow at the Rafik B. Hariri Institute at Boston University.

My research interests include Data Mining, Machine Learning, Web Search, and Algorithmic e-commerce. I am particularly interested in challenging problems from the domain of Social Media.

I got my PhD from the Dept. of Computer and Science Engineering at the University of California, Riverside (UCR), with a specialization in Data Mining and Social Media. While in UCR, I was a member of the Database Lab, working with Prof. Dimitrios Gunopulos and Prof. Vassilis Tsotras. The title of my thesis is "Algorithmic Challenges in Social Media Search". I received my Bachelor's in Informatics from the Athens University of Economics and Business, with a specialization in Information Systems.
