My name is Maria Christoforaki and (as of 2012-2013) I am a fourth year doctoral student in the Computer Science and Engineering Department of the Polytechnic Institute of New York University.

I am working with Professor Torsten Suel and my research focus is in the areas of Web Search, Information Retrieval, and Data Mining. In particular, I am interested in studying and applying techniques of these areas in managing and analyzing large scale datasets.

Before coming to NY I lived in Greece, where I received my Diploma from the Computer Engineering and Informatics Department of the University of Patras in 2009. My Diploma thesis advisors were Dr Ioannis Chatzigiannakis and Professor Paul Spirakis.

Research Intern @ Microsoft Research, CA - Summer 2012

At Microsoft Research, I interned in the Search Labs group and my work focused on automatically augmenting educational textbooks with videos. We proposed techniques for identifying the focus of a section in relationship to other sections in the book in terms of a few indicia, which themselves are unique combinations of concept phrases. We scored the candidate videos for augmenting a textbook section based on concept phrases from that section's indicia present in the auditory tract of the video. Our tests using two corpora of textbooks indicated that our system is able to find useful videos.

Data Analytics Intern @ LinkedIn - Summer 2011

At LinkedIn I worked on the InMaps product which provides a visualization of each member's network. In particular I worked on the community detection algorithm that colors the egonet vertices as well as on the automatic label suggestion of the detected communities.For the implementation I used Java and pig and the final work flow was deployed on the Hadoop cluster of LinekdIn.

Open Lab Summer Student @ CERN - Summer 2007

I participated in a project for a simulation of the BitTorrent protocol and chocking and unchoking algorithms by extending existing network simulator software.This demanded an in depth understanding of the structure and advantages of PlanetSim, the simulator, and the BitTorrent prorocol.

External Stagier @ CERN - Summer 2006

In cooperation with the CMS-experiment group I designed and implemented a web-based application for conferences concerning the CMS-experiment and their candidates, using a multi-tier architecture based on MySQL, Java Servlets, JSP and XML technologies.
