David Liben-Nowell
I'm a professor in
the Department of
Computer Science at Carleton College.
In September 2022, I joined the Provost's Office at Carleton, for a few-year stint as an Associate Provost.
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.

A textbook: Connecting Discrete Mathematics and Computer Science
I've written a textbook for computer science students learning discrete math.
A revised edition was published in 2022. You can find an electronic pre-publication version of the text at the above link, freely available for personal use. I'd be delighted by comments, corrections, and suggestions.

- History of Computing in England (off-campus studies program)
CS 301 History of Computing; CS 341 Cryptography; IDSC 141 Turing, Gender & Computing; HIST 145 World War II History.
- Previous offerings of the program ran in Summer 2019 and Summer 2022.
- The Fall 2025 program will run from September through November 2025.

FAQ:
- 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."
