I am a fifth-year Ph.D. student and NSF Graduate Fellow in the Department of Mathematics at the University of Notre Dame. My advisor is Claudiu Raicu.

Previously, I was an undergraduate at the University of Illinois at Chicago.

During academic year 2020-2021 I will be Coleman Postdoctoral Fellow at Queen's University, and starting Fall 2021 I will be Dunham Jackson Assistant Professor (postdoc) at University of Minnesota.

Here is my CV (last updated 3/24/2020).

My interests are in algebraic geometry, commutative algebra, D-modules, and their interactions with representation theory.

I like to study homological invariants of algebraic varieties, including local cohomology, syzygies, and mixed Hodge structure.

More recently, I have been thinking about singularities and invariants arising from birational geometry and the theory of D-modules (e.g. multiplier ideals, Hodge ideals, Bernstein-Sato polynomials).

- SchurComplexes.m2

(with Michael K. Brown, Hang Huang, Robert P. Laudone, Claudiu Raicu, Steven V Sam, and João Pedro Santos)

This package computes the Schur complex associated to a partition and a bounded complex of finitely-generated free modules over a commutative ring.

An introduction to the package may be found here. -
PossibleBettiTables.m2

(with Juliette Bruce and Mike Loper)

This package computes all possible Betti tables for zero-dimensional graded modules with a prescribed Hilbert function. - GLmnReps.m2

(with Claudiu Raicu)

This package is for computations with finite-dimensional representations of the general linear Lie superalgebra and syzygies of determinantal thickenings.

I grew up in the suburbs of Chicago (Bartlett, Schaumburg, Buffalo Grove).

Outside of mathematics, I am interested in listening to music (Rock, Hip hop, Techno) and film - I love to talk about movies.

In my free time I enjoy cooking, bicycling, and gardening - before pursuing math, I studied plant biology.

We have a Commutative Algebra and Algebraic Geometry Seminar at Notre Dame.
