Biography

Hi, I am Raymond. I am a fourth year mathematics PhD student at UCLA, where I am advised by Professor Inwon Kim. I was also an undergraduate at UCLA studying Applied Mathematics, where I was advised by Professor Marcus Roper.

I am honored to have recieved the Horn Moez Prize (2021) from UCLA Mathematics for my high academic achivements and an Honorable Mention (2022) in the National Science Foundation’s Graduate Research Fellowship. I have also recieved a teaching award Liggett Fellow Award (2023) from UCLA Mathematics.

Qualification Exams

While studying for my qualification exams, I found it very helpful to type out my solutions to old exams. I hope these resources help future students with their preparation for their exams.

Analysis Qualifying Exam:

[1] Old Exam Solutions: Analysis Qualifying Exam Solutions (Spring 2010 - Fall 2020) pdf

Basic Qualifying Exam Resources:

[1] Old Exam Solutions Basic Qualifying Exam Solutions (Spring 2010 - Spring 2020) pdf

[2] Math 204 Website Lecture Notes and Homework Made for Math 204 to prepare students for the basic Math 204 Website. The midterm given to the students in the class can be found on pdf.

[3] Math 131AH+131BH Lecture Notes Honors Real Analysis (Math 131AH and 131BH) lecture notes 131AH, 131BH 1/2, and 131BH 2/2.

The Honors Real Analysis Lecture Notes are from Professor Visan’s Math 131AH and 131BH class from Fall 2017 and Winter 2018. I would like to thank my friend Damien Lefebvre for typing up the lecture notes.
