Biostatistics PhD Program

Offered On Campus in Tucson

The UA Zuckerman College of Public Health offers the following doctoral degrees with a focus in Biostatistics: Doctorate (PhD) in Biostatistics, and a PhD Minor in Biostatistics.

The PhD in Biostatistics is offered by the Department of Epidemiology and Biostatistics. The doctoral degree program in Biostatistics will have an emphasis on the foundations of statistical reasoning and will require its graduates to complete rigorous training in applied probability and statistical analyses. This program prepares students who have demonstrated excellence in mathematics and the sciences to become research biostatisticians in academia, industry, or government.

To the extent possible, the curriculum of each student will be tailored to his or her background and interests. 

The doctoral program requires approximately four to five years for completion. The first two years of this time are usually devoted to coursework, the comprehensive doctoral examinations, and development of doctoral research. The program is research oriented and centers on a major research project. The overall course of study is developed by the student and the Faculty Advisor, and is approved by the student's Graduate committee and the Biostatistics Program Director. Students will be required to defend their dissertation through a public presentation and oral examination with their committee.

Curriculum

PhD in Biostatistics Competencies and Assessment Methods

Required PhD Courses (32 units)

Elective Courses* (minimum 15 units)

**Electives may also be chosen from other Statistics or Mathematics courses with approval of the Biostatistics Faculty.

Note:  BIOS 576A, Biostatistics in Public Health (3 units), is considered a prerequisite, which will have been met by most entering students.

Minor Courses (minimum 9 units)

Each PhD student must complete a minimum of 9 credit hours of course work in a minor area. The minor area of study specifies the number of required minor units. This should consist of a coherent set of courses in an area (or in related areas) of application of biostatistics; the courses may be from more than one program. Minor courses should be primarily applied as opposed to mathematics/statistical in nature.

Dissertation (minimum 18 units)

Admission Criteria Biostatistics PhD Program: Students with a prior MS degree in Biostatistics or Statistics are eligible for admission into the Biostatistics PhD program.  Students who enter the Biostatistics PhD program after completion of an MS degree from MEZCOPH, may use 23 units towards the Doctorate in Biostatistics (PhD). Thus, students with an MS must complete a minimum of 18 additional units of course work, 6 units of seminar, 9 units or more in a minor subject, and 18 dissertation units. They will be allowed to substitute more advanced courses for any required courses already completed.

Total Minimum Credit Requirements = 74 units


PhD Minor in Biostatistics

The PhD Minor in Biostatistics is designed for individuals from other University of Arizona doctoral degree programs who wish to obtain graduate training in Biostatistics.
