Research Interests

I'm interested in Data Mining, Signal Processing & Optimization Algorithms for Data Mining and Multi-way (Tensor) Analysis, as well Coupled Matrix-Tensor Analysis. More specifically, I'm currently interested in discovering how knowledge and information is expressed and stored in the brain, through analyzing brain scan data (possibly from diverse experiments), coupled with external information. Additionally, I'm also interested in anomaly detection on very large graphs, especially when temporal or multi-view information is present.

Web Presence

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 fourth year Ph.D student at the Computer Science Department of Carnegie Mellon University under the supervision of Professor Christos Faloutsos. During the summer of 2013, I interned at Microsoft Research Silicon Valley, at the Interaction & Intent group, working with Dr. Ariel Fuxman and Dr. Ashok Chandra on Contextual Search. During the summer of 2014, I worked with Dr. Rakesh Agrawal as an intern at the Search Labs, Microsoft Research Silicon Valley, on electronic education systems and social media web search. This summer, I will be interning at the Structured Data Group at Google Research. 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.
