I'm an associate professor in (and, as of July 2016, chair of)
the Department of
Computer Science at Carleton
College. My interests are focused on computational social sciences, particularly the structure and evolution of social networks and computational modeling of spoken-word recognition. I'm also generally interested in the application
of theoretical computer science to problems in a variety of other
areas, within and beyond computer science; I've worked on
problems in computational biology, complexity of games, and
Other interests, just because:
crossword puzzles (solving and writing),
Eddie From Ohio,
the Magnetic Fields,
someone who's learned a few of my tricks),
web pages that look like they were built in 1996.
The preliminary edition of my textbook for computer science students learning discrete math,
Discrete Mathematics for Computer Science (Wiley),
is now available!
As of July 1, 2016, you can redirect any
department-chair–related questions from to me. Especially if
you're an incoming first-year student, please feel free to get in
touch over the summer!

Letters of Recommendation:
If you'd like me to write a letter of recommendation for you,
please read and follow these
- Q: Hey you! What should I call you?
A: "David" will do quite nicely, thank you very much. "Dave"
is a perfectly fine name, but Dave ain't me. (Thanks to Charles
Leiserson for the FAQ idea.)
- Q: Hey you! I'd rather call you Professor/Doctor
Liben-Nowell. How is that pronounced?
A: It's pronounced many different ways, but the correct one
rhymes with "ribbon towel."
