Mathematics PhD Student

University of California, Los Angeles


I am a third year PhD student studying mathematics at UCLA, where I am advised by Professor Inwon Kim. I mainly study the Analysis of Partial Differential Equations and Integro-differential equations using tools from Stochastic Analysis, Optimization, and Mathematical Analysis.

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

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

Math 204 (Basic Qualifying Exam) I will be posting lecture notes and homework assignments here.

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.
