PhD in Statistics
The Doctor of Philosophy (PhD) program in Statistics prepares students for careers in industry, research institutions, and universities. The students initially undergo a sound training in theory and applied statistics, followed by advanced courses and dissertation research. Statistics faculty in the department work in diverse areas of research topics and are also actively involved in interdisciplinary research collaboration. This provides our PhD students a wide array of research topics to choose from for their PhD dissertation.
All PhD students have the opportunity to work as paid interns in the nearby industries and research institutions, such as Cincinnati Children's Hospital, Proctor & Gamble, and Medpace, after they finish a set of core applied statistics courses. The internships are coordinated by the Department. The Department is consistently successful in placing most of our students with an internship of student’s interest. The internship offers the students experience in applying statistical methods they learn to real-world problems under the mentorship of experienced statisticians and researchers, while they pursue their PhD degree. Students also have the opportunity to choose a PhD dissertation research topic related to their internship work.
The multifaceted training of our students, through course work, research, and the wide range of interdisciplinary experience through internship, sets our PhD program apart from other PhD programs in statistics. Our past students have had an extremely high success rate of employment in industries, research institutions, and universities after graduation.
Students applying for the program should have or be expecting to obtain a bachelor’s degree in statistics or a related area. 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 calculus-based probability and statistics
- Courses in pure and applied statistics similar to STAT 6021-6022 (Mathematical Statistics I and II) and STAT 6031 (Applied Regression Analysis) and STAT 6032 (Design and Analysis of Experiments).
An official GRE score is required for admission. This requirement is waived for UC undergraduates with a degree in a relevant field and a cumulative GPA of 3.5 or higher, for applicants with at least 6 graduate credits in a relevant field with a cumulative GPA of 3.2 or higher, or for applicants with numerous years of relevant work experience with demonstrated advancement. A quantitative score of 160 or higher is recommended.
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 54 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.
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.
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.

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.
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 the 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. The Statistics Qualifying Exam is based on the two two-semester sequences Mathematical Statistics STAT6021-6022 and Applied Statistics STAT6031-6032.
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.
