I am a Research Scientist at Facebook, in Menlo Park, California. I recently 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.
I recently co-organized the NIPS 2012 workshop on
Social Network and Social Media Analysis: Methods, Models and Applications,
held in Lake Tahoe, Nevada, on December 7, 2012. 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 in Manhattan, 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.
