About me

Hello there! My name is Vagelis Papalexakis (my 'official' name is Evangelos, but nobody really calls me that) and I come from the beautiful city of Athens, Greece. I received my Electronic & Computer Engineering Diploma and M.Sc at the Technical University of Crete in Chania, under the supervision of Professor Nikos Sidiropoulos.
Currently, I am a fifth and final year Ph.D candidate at the Computer Science Department of Carnegie Mellon University under the supervision of Professor Christos Faloutsos. This is my personal web page. Feel free to navigate through the menu on your left, where you may find a list of my publications, code for some of my projects, a brief bio and some interesting links.

I am on the academic job market, looking for a faculty position in Computer Science.
