I’ve just joined Amazon as a Principal Application Scientist at Amazon Alexa Shopping , Israel. My research will be focused on improving product search through Amazon’s Alexa device. I’m still interested in question answering, top-k query processing, query performance prediction, and social search. Previously I was at Yahoo research and for many years I was a Research Staff Member at the Information Retrieval group at IBM Haifa Research Lab. For several years I taught the Introduction to IR course at the CS department at Haifa university.
