Vivian Kuperberg

I am currently a third-year graduate student at Stanford University. I'm interested in analytic number theory and working with Sound.

I am involved with the Stanford Math DRP program.

The following is an incomplete list of nonacademic things I've been involved with.

  • This is the front and back of a shirt I designed with two of my friends for the Mathcamp community after Mathcamp 2013.
  • I designed this shirt in 2015 for the Cornell math department.
  • As an undergraduate, I helped organize Math Bake-Offs at Cornell. My submission to the 2017 bake-off (which was voted Prettiest Baked Item) was a Hopf-fibration cake.
  • For the 2019 prospective student visit at Stanford, Hannah Larson and I made baked goods. These included cookies with an alternating group action, brownies, and a double torus cake with a figure-eight knot embedded with no crossings on its surface (progress photos here and here).
  • I like puzzle hunts and co-wrote the Mathcamp 2018 and Mathcamp 2019 hunts.
  • This website's colors are compliant.
