I am an Associate working in the Relationship Analytics and Engineering Department of Goldman Sachs. I received my PhD from the Department of Computer Science of the University of Illinois, Urbana - Champaign. My research interests include Algorithms and Machine Learning. Before coming to the states, I attended the National Technical University of Athens, the University of Athens and the University of Oxford studying Mathematics and Computer Science.

In the past, I have worked as a summer analyst for Goldman Sachs in New York, NY, summer scholar for the Lawrence Livermore National Lab (LLNL) in Livermore, CA, as a research intern at the Verimag Institute in Grenoble, France, and as a full-stack web engineer for Pandynamic and Tripsta in Athens, Greece.
