PhD in Mathematical Sciences

The Doctor of Philosophy (PhD) program in Mathematical Sciences represents achievement of a broad knowledge of the various branches of mathematics and statistics, of the ability to communicate mathematics in both written and oral form, and of a demonstrated creative ability in a particular branch of mathematics or statistics. 

The program prepares students for careers in academia and as professional mathematicians and statisticians. Students have the opportunity to work with some of the world's leading experts in a variety of research areas. The Department has particular strength in the interrelated fields of analysis, partial differential equations, and probability. Students interested in more applied directions can work with experts in statistics, mathematical bioscience, computational finance, and cryptography.

Admission Requirements

Students applying for the program should have or be expecting to obtain a bachelor’s degree either in mathematics or statistics with a strong mathematical foundation. Specifically, all students should have taken: 

  • Three semesters of calculus up to and including multivariate calculus
  • A semester course in linear algebra
  • A semester course in each of ordinary differential equations
  • A semester course in calculus-based probability and statistics
  • A semester course in elementary set theory and logic. 

In addition, applicants should have taken or be taking advanced courses in mathematics or statistics at the level of the qualifying exams described in the Program Description below. 

Applicants intending to pursue a PhD in mathematics should have taken advanced undergraduate courses in linear algebra and analysis and additional advanced courses in pure and/or applied mathematics. 

A minimum score of 160 on the GRE quantitative section is required for admission.

Proficiency in English is required of international students whose native language is not English. A minimum score of 80 on the Internet-based TOEFL is required for admission. Also acceptable for admission are an overall band score of 6.5 on the International English Language Testing System (IELTS), a score of 56 on the PEARSON Test of English (PTE), or a score of 110 on the Duolingo English Test. To be eligible for a Graduate Assistantship, a student must achieve a TOEFL score of at least 93, IELTS overall band score of at least 7, PTE score of at least 64, or Duolingo score of at least 115. The English proficiency requirement is met for applicants with degrees earned in English from accredited universities and colleges in the US or other English-speaking countries

Financial Support

Most of our PhD students receive full financial support (tuition remission and a Graduate Assistantship, a fellowship, or an internship), and most are supported through their entire UC career.  Travel support is available for students to attend or present their work at conferences.  

All applicants for the PhD program are automatically reviewed for graduate assistantship eligibility at the time of application. 

Application Instructions

Applicants will need to meet the minimum requirements to be considered for the program. Completed applications will be reviewed beginning February 1. We will continue to receive applications until all positions are filled.

All application materials from international students requiring a US visa must be received prior to April 1 (but sooner is better) in order to allow time for the necessary paperwork to be processed. The visa application process can often take 90 days or more to complete.

How to apply: 

1. Create an online application

2. Include these documents in your application:

  • Three letters of recommendation. The application system will automatically send an email to each of the recommenders with a link to submit their letters. 
  • Unofficial copy of transcript (official transcript will be required if you are admitted to the program). 
  • GRE general test score 
  • Statement of purpose/cover letter 
  • English Proficiency for international students

3. Pay the application fee

UC’s CEEB college code is 1833, as established by The College Board. CEEB codes are used to ensure that test scores are sent to the correct institution. 

Program Description

The credit-hour requirement includes a minimum of 90 graduate credits beyond the bachelor's degree or a minimum of 60 credits beyond a master's degree, including 7 hours in dissertation research, with a GPA of 3.3 or higher. 

All incoming PhD students are required to take at least one qualifying exam before the beginning of their first semester. Students who do not pass this exam at the PhD level are placed in the appropriate 6000 - level courses. Mathematics Qualifying Exam is based on the two-semester sequence Advanced Calculus MATH6001-6002 and the one semester course Abstract Linear Algebra MATH6003. 

All PhD students must pass four preliminary examinations. Each Preliminary Exam is offered twice a year. Examinations based on a course given during Fall Semester are offered after the end of Spring Semester and at the beginning of the following Fall Semester. Examinations based on a course given during the Spring Semester are offered at the beginning of the Fall Semester and at the beginning of the following Spring Semester.

After the preliminary examinations, an advanced examination in the area of examination of the student is required. An advanced exam may either be a written exam, a presentation or a series of presentations. The exam will be administered by a committee. Generally, this committee will form the students’ dissertation committee.
