Teaching

I was a TA for Math 1920: Multivariable calculus for engineers during Fall 2021, Spring 2022, and Spring 2023.
I was an instructor for Math 1110: Calculus I during Fall 2022.
In summer 2023 I was an apprentice instructor at MathILy-Er.
I planned and taught a course on combinatorics and generating functions to students in the Ithaca High School math seminar during Fall 2024 and worked with students on related projects in Spring 2025.
In Spring 2025 I was a math instructor with the Cornell Prison Education Program. Unfortunately, the semester was cut short due to correctional officer strikes.

Mentoring

I've been involved with the Cornell Directed Reading Program through which I studied classical field theory, Erhart Theory, Greedoids, and Schottky groups with undergraduate students during Fall 2021, Fall 2022, Spring 2023, and Spring 2024 respectively.
During summer 2021 I was a graduate mentor on the "Finding Ellipses" project in the Polymath Jr. program.

Outreach

In Fall 2021 I facilitated a math circle through Cornell. I talked with a group of third and fourth graders each week and helped them to discover the beauty of fractals.
I have been a Graduate Student School Outreach Program (GRASSHOPR) fellow each spring since 2022. Each year I go to a local elementary school classroom to teach a workshop on fractals.

Teaching Seminar

I am a frequent participant in Cornell's teaching seminar. I have given presentations titles: "How students achieve mastery", "How learning works: motivation", and "Beginner level antiracist teaching." In spring 2023 I organized the teaching seminar, coordinated peer teaching observations, and ran several teaching reflection sessions as the teaching development fellow.
