My research interests include Algorithms design, Data Mining, Machine Learning, Optimization, Networks, and more. I prefer a principled approach to modeling and design and I am always looking to learn and expand my horizons. In the span of my research career, I developed models and scalable algorithms in a wide range of areas including query processing and optimization, data summarization, content search and delivery, caching, prefetching, routing, streaming and distributed computation, fundamental graph algorithms and scalable mining of massive graphs. My work enables the leveraging of much larger data sets than previously possible. More details on my work can be found on my personal web page.
I am a Research Scientist at Google (Mountain View, CA) since 2015. I am also a (visiting) full professor at the School of Computer Science at Tel Aviv University in Israel. I attended Tel Aviv University (Israel) for my undergraduate studies in math, physics, and computer science, graduating in 1985, and continued to obtain an M.Sc. in computer science in 1986, supervised by Michael Tarsi. I then headed to Stanford, CA, where I worked on a Ph.D. in Computer Science, with Andrew Goldberg and Nimrod Megiddo, graduating in 1991. From 1991 to 2012, I was a member of the research staff, first at the legendary AT&T Bell Laboratories , and after a 1997 split, at AT&T Labs Research. In 1997 I also visited the Computer Science Division at UC Berkeley. From 2012 to 2014 I was a principal researcher at Microsoft Research (Silicon Valley).
