Hello! I am a fourth-year graduate student in the math department at Princeton University. My advisor is János Kollár. I am interested in algebraic geometry and commutative algebra, particularly in positive characteristic.

Previously, I was an undergraduate at Columbia University, where I graduated in 2016. Outside of math, I like to take pictures of food and squirrels.

This is basically what I do.

Research:

- Structure of geometrically non-reduced varieties, with Joe Waldron. (Submitted). arXiv:1909.04014.
- Completely controlling the dimensions of formal fiber rings at prime ideals of small height, with Sarah Fleming, S. Loepp, Peter McDonald, Nina Pande, and David Schwein.
*Journal of Commutative Algebra*, Volume 11, Number 3 (2019), 363–388. - Controlling the dimensions of formal fibers of a unique factorization domain at the height one prime ideals, with Sarah Fleming, S. Loepp, Peter McDonald, Nina Pande, and David Schwein.
*Journal of Commutative Algebra*, Volume 10, Number 4 (2018), 475–498.

Here is my advice on how to apply to REUs.

Here is my CV.
