All candidates for the Ph.D. degree are expected to complete an integrated program of studies in mechanical engineering, mathematics, physics and/or chemistry in preparation for the Comprehensive Qualifying Examination.? Such preparation normally requires two academic years after the Bachelor?s degree.? The candidate is also expected to demonstrate his/her competence in certain basic courses appropriate to modern mechanical engineering to the satisfaction of the department. One or two years beyond the Qualifying Examination will usually be found necessary for the completion of an acceptable dissertation, whereupon the student will be required to pass the Final Oral Defense of the Dissertation. The candidate may, if he/she so desires, pursue for his/her dissertation an investigation in connection with any of the research projects in progress in the Mechanical Engineering Department or, in the case of interdisciplinary programs, in the School of Marine and Atmospheric Science or the Medical School.
