Dr. Elad Yom-tov (Visiting Scientist)

Information Management Engineering


Elad Yom-Tov is a Principal Researcher at Microsoft Research and a visiting scientist at the Technion, Israel. Before joining Microsoft he was with Yahoo Research, IBM Research, and Rafael. Dr. Yom-Tov studied Electronical Engineering at Tel-Aviv University and the Technion, Israel. He has published three books, over 60 papers (of which 3 were awarded prizes), and filed more than 30 patents (16 of which have been granted so far). He is a Senior Member of IEEE and held the title of Master Inventor while at IBM.

Elad’s primary research interest is in using Machine Learning and Information Retrieval to improve health, through the use of Internet data. Internet data such as social media postings and search engine queries are an important source for medical information, especially when collecting relevant data is hard or impossible using more traditional means, when the relevant activity takes place online, and when a more delicate sensor than that afforded by traditional medical information sources is needed. Examples of his work in this area include the discovery of a new class of side effects of drugs (using search engine logs), linking the portrayal of celebrities with the development of eating disorders (using search engine logs and social media data), and validating the usefulness of vaccination campaigns.
