Prospective Students
Molecular, Cellular, and Developmental Biology (MCDB) is an interdisciplinary program that allows graduate students to explore and discover the mechanisms of life processes. We offer a wide range of graduate research opportunities in plant, animal, and microbial systems at the cellular and molecular levels. The collaborative research efforts of over 50 (and growing) faculty in twelve departments provide an outstanding environment for graduate education and intellectual development. In the first year, students usually select a permanent lab for their Ph.D. research by participating in laboratory rotations that involve temporary but substantial research projects. After completing a balanced program of classroom study, and a major body of independent research that contributes significant new knowledge to the life sciences, the student is awarded a doctor of philosophy degree in Molecular, Cellular, and Developmental Biology.

Career Opportunities
Graduates of the MCDB program are highly qualified researchers with a solid grounding in molecular, cellular and developmental biological sciences. Moreover, they have the ability to think and perform research independently. This breadth and depth of training provides graduates with a wide field of post-graduate career opportunities. Many of our graduates choose research and/or teaching careers at major universities, medical schools, or small colleges. Other graduates choose positions in agricultural or pharmaceutical companies, or government laboratories.
Admission Requirements
Applicants are expected to have an undergraduate or advanced degree in one of the basic or applied life sciences. The following courses are required for admission into the MCDB Program:
- Mathematics, through one year of calculus
- Organic chemistry, one year
- Physics, one year
- Biological sciences, two years
Applicants may be admitted without one or more of these requirements if, in the judgment of the MCDB Selection Committee, any deficiency can be remedied by additional courses within the graduate program.
The MCDB program also requires the submission of official GRE general scores. GRE subject tests in biology or biochemistry are to the applicant's advantage. TOEFL is required of non-native speakers that have not obtained a degree from a United States college or university. The minimum acceptable TOEFL score (computer based) is 250.
