Jon Kleinberg

I am a professor of computer science at Cornell University. My research focuses on issues at the interface of networks and information, with an emphasis on the social and information networks that underpin the Web and other on-line media. My work has been supported by an NSF Career Award, an ONR Young Investigator Award, a MacArthur Foundation Fellowship, a Packard Foundation Fellowship, a Sloan Foundation Fellowship, and grants from Google, Yahoo!, and the NSF. I am a member of the National Academy of Engineering and the American Academy of Arts and Sciences.

Teaching

• For the past three spring semesters, David Easley and I have taught an introductory undergraduate course entitled Networks, covering the expanding role of networks in the study of phenomena across the social, technological, and natural worlds. See also the home page for the Spring 2007 and Spring 2008 versions of the class, as well as the class blog with posts by students taking the course.

• With Eva Tardos, I've written a book on Algorithm Design (Addison-Wesley, 2005), based on the undergraduate algorithms course that we teach.

• At the graduate level, I've developed two courses that cover topics related to my research:
  The Structure of Information Networks (Fall 2008) (and see also the original Fall 2002 version).
  Randomized and High-Dimensional Algorithms (Spring 2001).
