I am a sixth year graduate student in mathematics at Cornell University. My advisor is Michael Stillman and my research area is computational algebra. I grew up in Weaverville, North Carolina and spent my undergraduate years in Northfield, Minnesota at Carleton College, where I majored in mathematics, minored in Russian language, and took many courses in physics. In the past I have been a vegetable gardener, ballroom dancer, temporary Muscovite, ultimate frisbee player, mountain biker, clarinetist/saxophonist, math contest participant, and many others. Outside of math, I currently occupy myself with programming and running.

I am a recitation TA for MATH 2940 Linear Algebra for Engineers. My sections are

- Section 206: Th 12:20-1:10pm in Hollister Hall 320
- Section 207: Th 1:25-2:15pm in Hollister Hall 320-
- Section 209: Th 2:30-3:20pm in Hollister Hall 320

- Spring 2019 - MATH 2940 Linear Algebra for Engineers
- Fall 2018 - MATH 2940 Linear Algebra for Engineers
- Spring 2018 - MATH 1920 Multivariable Calculus for Engineers
- Fall 2017 - MATH 1920 Multivariable Calculus for Engineers
- Fall 2016 - MATH 1920 Multivariable Calculus for Engineers
- Fall 2015 - MATH 1920 Multivariable Calculus for Engineers
- Spring 2015 - MATH 1106 Calculus for the Life and Social Sciences
- Fall 2014 - MATH 1910 Calculus for Engineers

My primary research interests are in computational algebra, particularly efficient algorithms to compute Gröbner bases. In the past I have studied the arc algebra, a generalization of the Kauffman bracket skein algebra, under the direction of Helen Wong. I also studied Hadamard difference sets while at the 2013 San Diego State University Mathematics REU .

A current list of preprints can always be found on arXiv.

The DifSets package is a GAP package implementing an algorithm for enumerating all difference sets up to equivalence in a group. The package is not distributed with a standard install of GAP, but the latest release (2.3.0) is free to download here, and additional progress and updates can be found on GitHub. Installing the package allows one to perform exhuastive searches or get access to the results of the successful searches of 1006 of the 1032 groups of order less than 100 performed by the package.

The GroebnerWalk package is a Macaulay2 package implementing the Gröbner walk algorithm for computing Gröbner bases. The package is distributed with a standard install of Macaulay2 1.11 and later. The latest release (1.0.0) is also free to download here, and additional progress and updates can be found on GitHub.

I initially became interested in mathematics through math competitions, and I continue to enjoy solving puzzles related to math or programming. Puzzles I've recently been working on include those from Project Euler, Jane Street, FiveThirtyEight, and IBM Research.
