The Doctor of Philosophy degree is directed to attain proficiency in the pursuit of independent scholarly work. The degree comprises coursework in the general principles of materials, with emphasis on metallurgy, polymers, ceramics, paper science and engineering, or electronic materials. Additional requirements include specialized courses both in the area of the doctoral thesis and in one or two other areas, passing comprehensive examinations, and an independent research investigation.

Candidates for the doctoral degree are required to complete at least twenty-two credit hours of graduate-level coursework beyond the M.S. degree, with a minimum GPA of 3.0, and pass the course-based and oral parts of the Ph.D. qualification examination. Each student must also earn nine credit hours in a coherent minor field, chosen in consultation with the advisor, to satisfy the School's core course requirements. Students should commence participation in the School's research programs early in their graduate careers.
