# Nonacademics

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.
- Here is a drawing I made (mostly as an undergraduate, but with a recent implementation) of four mutually orthogonal latin squares, as “SET” cards.
- 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).
- In the summer of 2021, I made a toroidal cake with seven colored regions which are all pairwise adjacent.
- In November 2023, I made a (functional!) gingerbread abacus.
- I like puzzles and co-wrote the Mathcamp 2018, Mathcamp 2019, and Mathcamp 2022 puzzle hunts.
