I'm a professor in
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 peer-to-peer systems.
Other interests, just because:
crossword puzzles (solving and writing),
Eddie From Ohio,
The Girl Who Never Read Noam Chomsky,
the Magnetic Fields,
someone who's learned a few of my tricks),
web pages that look like they were built in 1996.
A textbook: Connecting Discrete Mathematics and Computer Science
I've written a textbook for computer science students learning discrete math.
I'm working on a revised edition, which will be out in early 2022. You can find an electronic pre-publication version of the text at the above link. I'd be delighted by comments, corrections, and suggestions.

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."
