FAQ List: (no title)






DBBS welcomes applicants with outstanding baccalaureate training in natural, physical or engineering sciences that are committed to a career in research. The strongest applicants will have had significant research experience and have a strong undergraduate record not only in their area of concentration, but also in related disciplines. For example, some of our programs will give preference to applicants who have strong training not only in biology, but also 3 to 6 semesters of chemistry (including biochemistry) as well as appropriate course work in calculus and physics (1 to 2 semesters each). Other programs, depending on their emphasis, will consider individuals with less extensive backgrounds in chemistry, physics, psychology or mathematics but with related training in biology. For example, Biochemistry, Biophysics, and Structural Biology gives preference to applicants that have completed one semester of physical chemistry or an equivalent course.

Minimum Requirements:
  • All applicants must have a U.S. bachelor’s degree or its equivalent from an accredited institution.
  • The Graduate Record Examination (GRE) General test is not required to apply to DBBS.  However, it is optional for some of DBBS Programs. Scores must be from tests taken in the last five years. The Subject test is not required.  If you will be applying to one of those programs and wish to submit a score (NOT REQUIRED), applicants are strongly encouraged to schedule the exam early so the official scores will reach DBBS before the December 1 deadline. See “Test Scores” below for additional information.
  • Proficiency in English is required of all applicants. Applicants whose native language is not English must demonstrate English proficiency and are required to provide an official score report from the Test of English as a Foreign Language (TOEFL) or the International English Language Testing System (IELTS). Only scores from tests taken within the last two years will be accepted. To be eligible for an automatic (no request needed) TOEFL/IELTS waiver the applicant must have completed a full-time bachelor's or master's degree from a regionally accredited university located in the United States or an institution where English is the primary language of instruction. PLEASE NOTE: The US Immigration service may require a TOEFL/IELTS​ exam score if the entire program of study is less than 3 years in duration.
