I am an assistant professor at the University of Colorado Boulder. My research area is theoretical computer science, with an emphasis on lattices and geometric algorithms.

Previously, I was an assistant professor at Oregon State University, did postdocs at the University of Michigan and Northwestern University, and completed my Ph.D. at New York University. My CV is available here. My email address is huck.bennett@colorado.edu.

In my spare time I enjoy running, mountaineering, and skiing. Additionally, I enjoy reading and playing Go.

I am originally from the bustling metropolis of Hygiene, CO, which was named for the sanitarium that it once housed, and which is now most famous as the home of Apple the Cow.

My full first name, Huxley, is actually an English last name.
