The application period for Fall 2019 entry is open. The deadlines are January 15th for Ph.D. (and priority applications for M.S.) and May 15th for M.S.


The Biostatistics graduate program at UC Davis is targeted toward students who are attracted to statistics, but who also wish to understand the interface between problems of the life sciences, data, and the more theoretical aspects of models and methods. Applications for the Biostatistics Graduate Group are made online at the Office of Graduate Studies.

Women, members of underrepresented minority groups and individuals with disabilities are strongly encouraged to apply.

Admissions Requirements


An undergraduate major in Mathematics, Statistics, Biostatistics or Biological Sciences with a quantitative orientation is typical for Biostatistics graduate students but is not required. However, because of the mathematical nature of some of the graduate coursework, students should be able to demonstrate good mathematical ability and should have taken coursework in mathematics. Students preferably would have had some exposure to courses in the life sciences (biological, environmental, medical, and agricultural sciences). Students without sufficient coursework in mathematics or life sciences may be admitted on the condition that deficiencies will be corrected during the first year of study. Applicants for the Ph.D. must have completed the course requirements (or their equivalents) for the M.S. degree in Statistics.

The minimum requirements for the Biostatistics graduate program are as follows:

  • Bachelor’s Degree with overall GPA of 3.0 or above
  • Undergraduate major in Mathematics, Statistics, Biostatistics, or Biological Sciences with quantitative orientation is typical for Biostatistics graduate students, but is not required
  • Demonstrate good mathematical ability
  • Exposure to courses in the life sciences (biological, environmental, medical, and agricultural sciences)
  • One year of calculus
  • One course of Linear Algebra
  • Facility with a programming language
  • Upper division coursework in Mathematics and/or Statistics. Upper division coursework in Biology and/or Biostatistics is strongly recommended
  • GRE, minimum score of 295 verbal and quantitative combined; scores must not be more than five years old prior to quarter of admission.
  • For applicants whose native language or language of instruction is not English must achieve the minimum TOEFL or IELTS scores listed on the Office of Graduate Studies website. For updated TOEFL and IELTS scores information, please check the Office of Graduate Studies website here.

Please keep in mind that the application process is very competitive, and that only a handful of students are admitted each year, from a strong pool of applicants. Each part of the application is important, and we look for solid overall applications which are the best fit to our program.

Funding is available in the form of fellowships, employment within the graduate group as a Teaching Assistant or as a Graduate Student Researcher with a specific professor; prospective students are encouraged to contact faculty members with whom they are interested in conducting research prior to application, though it is not a requirement for (nor guarantee of) admission. Teaching Assistants and Graduate Student Researchers are eligible for tuition remissions. There are also a limited number of fellowships available to help pay for non-resident tuition.  Please note: funding is currently only available for Ph.D. applicants.
