I am a postdoctoral fellow in mathematics at the University of British Columbia in Vancouver, mentored by Omer Angel and Jonathan Hermon. I received my Ph.D. in mathematics from the University of Washington in 2026, where I was advised by Christopher Hoffman.

Academic Positions

2026–present: Postdoctoral Fellow in Mathematics, University of British Columbia, Vancouver
Mentors: Omer Angel and Jonathan Hermon

Research Interests

I work in probability theory, with interests in interacting particle systems, stable matching problems, and pattern-avoiding permutations.
