Hi, I am Raymond. I am a fifth-year Mathematics Ph.D. student at UCLA, where I am advised by Professor Inwon Kim. I also completed my undergraduate studies at UCLA, majoring in Applied Mathematics under the guidance of Professor Marcus Roper.

For the 2024-2025 academic year, I am supported by the Dissertation Year Award. I am honored to have received the Horn Moez Prize (2021) from UCLA Mathematics for my high academic achievements and an Honorable Mention (2022) in the National Science Foundation’s Graduate Research Fellowship. Additionally, I was awarded the Liggett Fellow Award (2023) for excellence in teaching.
