General Info

I am a fifth-year graduate student at the University of Nebraska-Lincoln. My field of research is commutative algebra; I am most interested in symbolic powers of ideals, the containment problem, and symbolic defects. My advisor is Alexandra Seceleanu. You can find my CV here.
Publications, Preprints and Notes

Here is a list of my papers and preprints:
  1. "Aymptotic invariants of ideals with Noetherian symbolic Rees algebra and applications to cover ideals" with Lorenzo Guerrieri (submitted).
  2. " Computations involving symbolic powers" with Eloisa Grifo, Alexandra Seceleanu, and Branden Stone Journal of Software for Algebra and Geometry, vol. 9, no.1 (2019), 101-109.
  3. "Configurations of Linear Spaces of Codimension Two and the Containment Problem"
  4. "On a Class of Non-commutative Imprimitive Association Schemes of Rank 6" with Christopher French (Communications in Algebra Vol. 43, 2015 - Issue 9)


I co-organize the graduate student commutative algebra seminar (CARS) at UNL


This semester, I am teaching Math 103: COllege Algebra and Trigonometry. My office hours are Tuesday 1:30-2:30 and Friday 11-12.
At UNL, I have been an instructor of record for the following classes. The number of asterisks (*) indicate the number of sections of this course I have taught. Additionally, I was a recitation TA for Math 106, Calculus 1.
