About Me

I am a PhD student in mathematics. My advisors are Giulio Caviglia and Linquan Ma. I am on the job market this fall.

My research interests are in commutative algebra and its interactions with algebraic geometry, homological algebra and combinatorics. I worked on problems regarding the graded-irreducibility of graded modules, generic initial ideals, Boij-Soderberg theory for local cohomology tables, Lech's conjecture on multiplicities of flat local extension of Noetherian local rings, and singularities in prime characteristic. I have proved a new case of Lech's conjecture, and have found a way to decompose the local cohomology table of almost Cohen-Macaulay modules.

Commutative Algebra Student Seminar

In Spring 2022 I organized a commutative algebra student seminar. For more information about the seminar, please see here.

ICTP Summer School

In Summer 2022 I was a tutor in the ICTP summer school "Graduate Course on Tight Closure of Ideals and its Applications"
