Graduate Catalog 1993-1994 College of Engineering Department of Chemical Engineering Requirements for the Ph.D. Degree Students may elect to study directly toward a Ph.D. upon enrollment or may obtain the M.Ch.E. degree first. In either case, students must strengthen their engineering skills with appropriate course work, including courses in a "minor" area of concentration. The minor field may be selected from related subject matter in chemistry, mathematics, materials science, physics, biology, or other engineering disciplines. Admission to the Ph.D. program in chemical engineering formally requires passing both oral and written qualifying examinations prepared by the department. The written examination is made up of separate examinations in the chemical and the physical sciences. The oral examination includes presentation of a research proposition by the candidate to demonstrate the ability to devise and develop a research idea.
