The general requirements for admission to the Ph.D., M.S., or M.E. programs include a bachelor's degree from an accredited college or university, a completed application packet with short essay and letters of recommendation. GRE scores are optional. TOEFL scores are required for international students whose first language is not English. Qualified applicants who are deficient in certain prerequisites may be admitted with the expectation that they will remedy the deficiencies during the master's program. Prerequisite courses include introductory chemistry and biology, physics (two semesters based on calculus), mathematics through differential equations and computer programming (Matlab, C++ or Java). We evaluate each application on its own merit recognizing that a diverse student body has diverse backgrounds. You may find it helpful to know that a typical entering class of graduate students has an average undergraduate GPA above 3.5 on a 4-point scale. For students whose first language is not English, TOEFL scores of 250 computer-based/600-paper based, IELTS scores of 7.0 or above or iBT scores of 90 to 100 are recommended.
