A baccalaureate degree in the natural or physical sciences is required. Undergraduate level courses in organic and analytical chemistry, cell biology, biochemistry and genetics are strongly encouraged.  Undergraduate mathematics through calculus and physics are also recommended. See individual Program Admissions information for program-specific required or recommended courses.


The Graduate School recommends that entering students have a minimum grade point average (GPA) of 3.0 on a 4.0 scale and a minimum combined verbal/quantitative score on the Graduate Record Exam (GRE) of 300 (new test) or 1100 (old test).

International students must submit scores from the Test of English as a Foreign Language (TOEFL) earned within the last two years.  Applicants with scores of 600 (paper-based)/250 (computer-based)/100 (internet-based) or higher will be considered.


Undergraduate or postgraduate research experience of a minimum of 6 months is usually essential.


Applications are reviewed by the GBS Admissions Committee, representing all GBS thematic programs. Acceptance will be based on a combination of factors including:

  • Undergraduate performance (both the curriculum and grade point average)
  • Letters of recommendation
  • GRE scores
  • A personal statement of research and career interests
  • Previous research experience
  • Personal interview, at program expense (international applicants may be interviewed by phone or video conference)

Admission to our Programs is very competitive and the number of positions is limited; thus not every qualified applicant can be offered a position.
