Doctor of Philosophy (PhD) Degree

A PhD degree in Biostatistics requires a program of courses selected from biostatistics, statistics, and at least one other subject area (such as biology, environmental health, epidemiology), a qualifying examination and preparation of a dissertation. Courses cover traditional topics as well as recent advances in biostatistics and in statistics. Those completing the PhD will have acquired a deep knowledge and understanding of these subject areas. Since graduates with doctorates often assume academic careers in research and teaching, a high degree of mastery in research design, theory, methodology and execution is expected as well as the ability to communicate and present research findings and area of expertise in a clear, understandable manner.
 
The PhD degree program requires 4-6 semesters of course work followed by 2-4 semesters to complete examinations and prepare a dissertation (a minimum of four semesters of registration is required). Since there are no unit or course requirements for the PhD, a program of courses appropriate to a student's background and interests may be developed.
 
All students in the Biostatistics PhD program hold a master's degree in Biostatistics or a related field and those applying for PhD study who do not already hold a masters degree are considered for admission to the Biostatistics MA. This practice does not prolong the time to the doctorate since the first two years of both the MA and PhD programs for students coming from the baccalaureate are identical.
 
 

Coursework

The PhD degree requires 4-6 semesters of course work in biostatistics, statistics, and at least one other subject area (e.g. biology, environmental health, epidemiology). There are no unit or course requirements for the PhD, so a program of courses appropriate to a student's background and interests may be developed.

    The two other major components of the PhD degree program are...
    The Qualifying Examination

    The oral qualifying examination (QE) is scheduled for three hours. The primary purpose of the exam is to test both a candidate's general competence in the field of Biostatistics and the ability to apply biostatistical methods to a broad research area. The exam is designed to measure the candidate's breadth of knowledge as well as provide a determination of the candidate's readiness to enter the research phase of study.
     
    To assure the examining committee that the candidate has a firm grasp of both basic areas and a familiarity with current problems in the field, the exam is conducted as follows:
    1. The candidate is expected to begin with a 30 minute presentation of a proposed dissertation topic that includes a sound research strategy that the candidate can defend.
       
    2. Following this presentation, the candidate will be asked to demonstrate an ability to synthesize the methods and techniques learned through course work and to apply this knowledge to areas and problems suggested by the committee members. To achieve this goal, committee members are likely to ask questions that delve into subjects that go beyond the chosen area of dissertation research.
    Students are encouraged to take the qualifying exam after they have identified a dissertation advisor and a research topic. In preparation for the exam, the candidate should meet with the Chair of the qualifying examination committee to discuss the details of the structure of the exam and any other pertinent issues.
     
     

    The Dissertation

    After completion of course work and the Qualifying Examination, a doctoral student must apply to advance to candidacy for the PhD. Before this is possible, a student must have identified:
    1. a dissertation topic
       
    2. a dissertation advisor
       
    3. and a committee.
    Advisors and committee members are particularly interested in working with candidates who have demonstrated an ability to perform original research, and doctoral students are encouraged to explore dissertation research topics early in the program. Topics for research are selected from biostatistics and statistics, public health, biology, computing and other areas (see dissertation topics of some recent graduates).
     
     

    Since the inception of the program in 1955, the Group in Biostatistics has produced more than 100 doctoral graduates. A number of these people have gone on to teaching careers at colleges and universities, both here in the US and internationally. Others have pursued careers as Biostatisticians in the pharmaceutical/biotech industries, health care delivery organizations, medical schools and schools of public health across the US and abroad. The demand for biostatisticians with advanced training is high, particularly for those seeking teaching and research careers.
