I am an assistant professor at the Rutgers School of Communication and Information, in the department of Library and Information Science, where I run the Social Media Information Lab. I am also the Co-founder and Chief Scientist at Mahaya, Inc. Earlier, I spent some time at Yahoo! Research Berkeley, and at Stanford.
My research focuses on social information and social media, with excursions to mobile and multimedia applications: what can we learn from the activity of people on social media services about the world, about society, and about people?
