I am a researcher in Core Data Science, working on user privacy, improving the quality of feed, fighting hoaxes and scams, and personalizing content. I also work on trending in Instagram. Before Facebook I was a researcher at Technicolor labs. I received my Ph.D. and MS.c. in Electrical Engineering from Tel-Aviv University, where I studied routing and network topology of the Internet, and large-scale peer-to-peer recommender systems.
