I am a fifth year PhD candidate studying applied mathematics at UCLA. On May 1, 2025, I successfully defended my thesis! I work with Professor Deanna Needell, and I am supported by the NSF Graduate Research Fellowship. Previously, I attended Calvin University, where I obtained bachelor’s degrees in mathematics and chemistry, with a minor in computer science. I am broadly interested in the mathematics of data science; I am currently working on various projects related to machine learning on manifolds. I am also interested in low-rank matrix and tensor approximation and issues of bias in machine learning.
