I'm a fifth-year PhD student in the UCLA mathematics department. I'm advised by Mason Porter, and I'm currently supported by a UCLA Dissertation Year Fellowship. In my research, I focus primarily on topological and geometric data analysis, and I sometimes use tools from computational geometry as well. I also have an interest in network science, especially opinion dynamics and network geometry. Prior to UCLA, I was an undergraduate in the Princeton math department.

I'm currently on the job market for postdoc positions that start in fall 2023! Here is my CV.

Outside of math, I enjoy rock climbing, running, and playing and composing for piano.

Upcoming talks and travel
