    Bio
    I joined the Human & Social Dynamics group at Yahoo! Research led by Duncan Watts in August 2008. Prior to that I was a postdoctoral associate working with Jon Kleinberg in the computer science department at Cornell University. I earned my Ph.D. in computer and information science from the University of Pennsylvania in January 2007 under the supervision of Michael Kearns. If you would like more information about my background, please see my CV. My research takes an interdisciplinary approach in studying the computational aspects of social networks as well as economic networks. Many modern technological networks such as the Internet, the World Wide Web, Facebook, and eBay involve social and/or economic interactions. Thus, I use theories from sociology and models from economics in my study of algorithmic questions about these types of networks. For more information please see my research statement.
