PhD Program

The Doctor of Philosophy (PhD) program is designed to prepare students for scholarly and professional positions and careers in academic institutions, public agencies, and industry. The objective of doctoral study is to develop each student's ability to conduct original, advanced research as an independent scientist.

In keeping with this goal, each student is expected to guide his or her own research project, under the supervision of a faculty member, with a high level of effort and accomplishment, and thereby gain the capacity to be self-teaching and the ability to design and conduct research on important issues in the student's chosen field. The program typically entails four or more years of full-time study and research beyond the baccalaureate.

Biomedical Sciences

The doctoral program in biomedical sciences offers intensive laboratory and field training. In addition to this wet bench training, students develop research planning, communication, and quantitative skills required for successful leadership roles in academia, government, and industry. These scientific, planning, and communication foci distinguish the PhD degree from the MS degree, which is more general. The program leading to the PhD degree typically requires five years of full-time study, culminating in the completion of a doctoral dissertation. (Degree requirements)

Basic Admission Criteria

  • Must hold a bachelors degree from a college or university of recognized standing
  • Grade point average of 3.00 or better
  • Submit GRE scores
  • Satisfactory records of achievement and scholarship
  • Combined total of at least 42 credits in biology, chemistry, mathematics and physics
  • Minimum TOEFL score of 100 for international applicants


Biostatistics

Graduates completing the Biostatistics concentration will be prepared to serve as collaborators in public health projects, providing expert advice on the use of statistics in the analysis of public health data. Students will gain a strong foundation in the core areas of statistical science, develop skills in defining a problem and determining the variables that are relevant to solving a public health problem, understand the appropriate use of data, the integrity of data sets, and how data might be used in public health issues, and acquire specialized knowledge in two areas of statistical science. (Degree requirements)

Basic Admission Criteria

  • Must hold a bachelors degree from a college or university of recognized standing*
  • Grade point average of 3.00 or better
  • Submit scores of the GRE or MCAT.  Minimum GRE scores required are 600/160 Verbal; 600/143/Quantitative; 5.0 Writing
  • Satisfactory records of achievement and scholarship
  • Concentration (undergraduate major) in the biological, physical, or social sciences, computer science, mathematics or statistics. *
  • Minimum TOEFL score of 98 for international applicants

*A major in mathematics, statistics, computer science, the biology, physical or social sciences is required.  Linear algebra, multivariate calculus and computer programming are required for successful completion of the program.  Highly qualified students who are deficient in these prerequisites may make up such deficiencies.


Environmental Health Sciences

The doctoral program in Environmental Health Sciences emphasizes the application of biological, physical, and medical sciences to the solution of environmental and public-health problems, and is designed to prepare students for technical, teaching and research careers in academia, public health agencies and industry. The objective of doctoral study is to develop each student's ability to conduct original, advanced research as an independent scientist.  In keeping with this goal, each student is expected to guide his or her own research project, under the supervision of a faculty member, with a high level of effort and accomplishment, and thereby gain the capacity to be self-teaching and the ability to design and conduct research on important issues in the student's chosen field.

  • Combined total of at least 42 credits in biology, chemistry, mathematics and physics.
  • Minimum TOEFL score of 100 for international applicants


Epidemiology

Graduates completing the Epidemiology concentration will understand the design, application and interpretation of epidemiological studies of public health problems in the community. Students will become familiar with the range of epidemiologic practices, including surveillance, etiologic investigation, and the evaluation of preventive interventions.

They will be able to define, compute and interpret fundamental epidemiologic measures, explain the principles, strengths and weaknesses of epidemiologic study designs, know how to apply the fundamental techniques for selection of study populations, have experience with techniques for collecting data and evaluating the quality of data, demonstrate basic skills for managing computer-based data, and demonstrate the ability to interpret and present the results of epidemiological research. (Degree requirements)

Basic Admission Criteria

  • Must hold a master's or doctoral degree from a college or university of recognized standing.  Exceptional students with bachelor's degree will be considered.
  • Grade point average of 3.00 or better
  • Submit scores of the GRE or MCAT.  Minimum GRE scores required are 600/160 Verbal; 600/143/Quantitative; 5.0 Writing
  • Satisfactory records of achievement and scholarship
  • Concentration (undergraduate major) in the biological, physical, or social sciences, computer science, mathematics or statistics. *
  • Minimum TOEFL score of 98 for international applicants

*Students with concentrations in areas other than those listed may be admitted on the basis of relevant work experience and course work as a non-major in the recommended disciplines. At least one semester of college-level mathematics and biology is strongly advised. Students lacking preparation in the biological sciences will be required to take additional course work in this area.
