Khalid El-Arini

Research Scientist


I am a Research Scientist and Engineering Manager at Facebook, in Menlo Park, California, working on News Feed. I completed my Ph.D. in Computer Science at Carnegie Mellon University, on the subject of machine learning methods for personalization. My advisor was Carlos Guestrin, and I was a member of the SELECT Lab.

In 2016, I co-organized the ICML workshop on Computational Frameworks for Personalization. I've co-organized NIPS workshops in 2014 on Personaliation: Methods and Applications, and in 2013 and 2012 on social networks and social media analysis. In 2011, I co-organized the Workshop on Enriching Information Retrieval (ENIR 2011) at SIGIR 2011, in Beijing, China, July 28, 2011.

In the summer of 2011, I interned at Microsoft Research Cambridge, working with Ralf Herbrich on transparent user models for personalization. From February 2007 through August 2008, I took a leave of absence from the Ph.D. program in order to spend some time in industry. I spent three months at Google New York, where I worked on Personalized Search. This was followed by a year at MITRE in McLean, Virginia, where I applied machine learning to national policy problems, primarily working with the Securities and Exchange Commission and other agencies of the federal government.

I received undergraduate degrees in Computer Science and Electrical and Computer Engineering, with a minor in political science, from Carnegie Mellon University in 2004. I received a Masters degree in Computer Science, also from Carnegie Mellon, in 2006.
