Default Credentials

PhD - Doctor of Philosophy

Program Description

The Doctor of Philosophy (PhD) program in Biostatistics and Data Science will produce graduates equipped to conduct cutting-edge research, teach the next generation of biostatisticians and data scientists, and collaborate with basic research scientists, clinicians, epidemiologists, and population health organizations. The doctoral course of study includes supervised consulting, internships, and a dissertation expanding knowledge in one or more emphasis areas, namely biostatistics, data science, or bioinformatics & genomics. Students must install the following statistical programs onto their personal laptops prior to orientation: Stata, R, and SAS OnDemand for Academics.

Collect biomedical, clinical, and population health data.

Clean biomedical, clinical, and population health data.

Organize biomedical, clinical, and population health data.

Analyze biomedical, clinical, and population health data.

Conduct all facets of big data analysis, including the extraction, storage, manipulation, and analysis of massive genetic and bioinformatics datasets.

Convert information contained in databases and data warehouses into actionable findings using machine learning and other data science techniques.

Adhere to rigorous ethical and methodological standards when analyzing real-world data;

Collaborate with non-statisticians and communicate findings to the scientific and general community to improve health care and prevent disease;

Lead cutting-edge methodological, genetic epidemiological, or data science research;

Act as a consummate resource in the design, analysis, and interpretation of a wide array of studies.

Admission Requirements

The program accepts students for fall enrollment. To be considered for fall admission, all applications must be submitted and completed by June 1.

PhD in Biostatistics and Data Sciences applicants will be evaluated based on the following:

  • Baccalaureate degree in a relevant scientific discipline

  • Grade Point Average (GPA) of 3.0 or better (preferred)

  • Three letters of recommendation

  • A personal statement

  • Curriculum Vitae

  • GRE; A GRE score >300 on the combined verbal and quantitative scores is preferred.

In addition, applicants must have documented training in calculus (including multiple variable integration and differentiation) and linear algebra. Additional training in programming languages is preferred. Applicants may submit code exhibiting their knowledge in a statistical or computer programming language and/or slides presenting a completed data analysis project. These materials are optional but may strengthen the overall application.

Degree Requirements

Program Completion Requirements

The PhD degree is a research degree and is not conferred solely as a result of formal course work, no matter how superior and extensive. The program leading to the PhD degree represents more than the sum of time in residence, and the plans of study listed below are only a minimum. To receive the doctoral degree, the candidate must demonstrate evidence of proficiency and distinctive attainment in a special field and a recognized ability for independent investigation as presented in a dissertation based upon original research.

Comprehensive Examination

The comprehensive examination covers four first-year courses, namely BDS 721: Analytics, BDS 722: Advanced Analytics, BDS 741: Statistical Inference I, and BDS 751: Statistical Inference in Genetics. The comprehensive exam is offered in May to students who have completed the requisite coursework. Students must successfully pass this exam before undertaking the qualifying examination.

Qualifying Examination and Admission to Candidacy

The qualifying examination is given to graduate students in good academic standing upon completion of coursework and successful passage of the comprehensive examination. The qualifying examination must be successfully completed for admission to candidacy for the Doctor of Philosophy degree. This examination includes a 45-minute oral presentation of a biostatistics or data science project that the student completed under the mentorship of a program faculty member. The examination panel includes the research mentor and two additional faculty from the Biostatistics and Data Science program.

Dissertation

The dissertation must show the originality of thought and demonstrate the results of independent investigation. It should contribute to the advancement of knowledge, exhibit mastery of the subject literature, and be written with an acceptable degree of literary skill. The dissertation, written according to the prescribed form, is prepared under the direction of the candidate's advisor and must be approved by the candidate's doctoral advisory committee and the Dean of the SOPH. This approval must be obtained, and all other requirements must be completed by the date given in the official academic calendar. Guidelines outlining the prescribed form for a student's written thesis can be found on the SOPH Dissertation and Thesis website.

Dissertation Proposal and Dissertation Defense

The oral dissertation proposal defense to the doctoral advisory committee and dissertation defense to the public are mandatory for the successful completion of the dissertation. The candidate's advisory committee will oversee the dissertation process. See the SOPH Thesis and Dissertation Defense policy for details.

Publication Requirement

A student enrolled in the Biostatistics and Data Science Doctor of Philosophy (PhD) program must have the results of their co-author research accepted for publication and the results of their first-author research submitted for publication before the awarding of the degree, as outlined in the SOPH Student Publication Requirement policy.

Required Coursework

Students must successfully complete BDS 706: Ethics in Biostatistics and Data Science Research and Practice.
