The program is intended only for students whose research is best supported by a collection of courses that is interdisciplinary and so would not meet course requirements for any other major. As part of the application process, the applicant must choose an Engineering Science concentration from either Aerospace, Biomedical, Civil, Energy Science and Engineering (Bredesen Center), Environmental Engineering or Mechanical Engineering programs. The student's departmental home is that of the chosen concentration and of the student's major professor.
