Nir Grinberg is an Assistant Professor at the Department of Software and Information Systems Engineering at Ben-Gurion University, Israel. His research investigates social behavior in large-scale, online information systems. He studies areas where information systems are suboptimal for people -- for example, by not meeting people's needs, goals or expectations -- and proposes new computational measures to bridge the gaps. For example, he studied the scale and scope of fake news on social media and develops methods for limiting its spread, audits large-scale algorithmic systems such as Google Search and Gmail to reduce bias and inequality, and examines online user engagement with news in order to promote better measures for quantifying it. He collaborated on research projects with top industry partners such as Facebook, Yahoo! Labs, Chartbeat, SocialFlow, and Bloomberg L.P. He holds a Ph.D. in Computer Science from Cornell University, a M.Sc. in Computer Science from Rutgers University, and a double major B.Sc. in Physics and Computer Science from Tel Aviv University.
