Raymond Chu

Mathematics PhD Student

University of California, Los Angeles


Hi! I am a second year PhD student studying mathematics at University of California, Los Angeles (UCLA), where I am advised by Professor Inwon Kim. I am interested in the connection between Partial Differential Equations and Probability Theory.

As an undergraduate, I studied Applied Mathematics at UCLA and worked with Professor Marcus Roper on inertial migration of particles.

I am also interested in mentoring undergraduates. I am currently a committee member and mentor for the Directed Reading Program (DRP) at UCLA. I am also a graduate student represenative for the Undergraduate Studies Committee.

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: Analysis Qualifying Exam Solutions (Spring 2010 - Fall 2020) pdf

Basic Qualifying Exam: Basic Qualifying Exam Solutions (Spring 2010 - Spring 2020) pdf

Basic Qualifying Exam: 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.
