I am one of the founding members of Microsoft Research, New York City.  Before that I was a member of the Human & Social Dynamics group at Yahoo! Research led by Duncan Watts from 2008 to 2012.  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 2007 under the supervision of Michael Kearns.  If you would like more information about my background, please see my CV.

There are two main threads to my research. Both focus on the study of networks, albeit using different techniques. I design algorithms for analyzing the structure of large graphs using the MapReduce programming paradigm. I also conduct web-based behavioral experiments to understand how network topology impacts human behavior. To see my research agenda for both of these threads please read my research statement.
