Take Your Knowledge to the Highest Level at UC Davis

About the Doctoral Degree

The doctoral (Ph.D.) degree prepares students to solve complex, long-term research problems. You can expect to graduate in four to five years and to work on a large research project, culminating in a dissertation. The majority of our doctoral graduates end up in industry careers, usually in research and product development positions. Others go on to careers in academia, either as a postdoctoral researcher or an assistant professor. Check out the "After UC Davis" page for examples of where some of our graduates have found employment. 

Degree Requirements

Doctoral students complete the same core courses as the master’s degree students, but have additional examinations along the way that test both the breadth and depth of their materials science and engineering knowledge. Over the course of your first fall quarter, you will be matched with a major professor through the "Preparing for Graduate Student Success" course (EMS 200). The five core classes mentioned above are listed below: 

  • EMS 260: Advanced Thermodynamics of Solids.
  • EMS 262: Advanced Topics in Structure of Materials. 
  • EMS 264: Transport Phenomena in Materials Processes. 
  • EMS 272: Advanced Functional Properties of Materials.
  • EMS 274: Advanced Mechanical Properties of Materials. 

For electives, you can select from any available upper-division undergraduate course (courses numbered 100-199) or graduate level course (courses numbered 200-299) in a science or engineering discipline. Doctoral students are encouraged to select any physics, chemistry, mathematics or engineering-related courses that will assist them in preparing for their dissertation research. 

You are also expected to enroll in EMS 290: "Department Seminar" every quarter until you have advanced to candidacy. The course requires students to attend a majority of the weekly departmental lectures by visiting scholars in the field, exposing them to the latest advances in materials science and engineering.

In years three and four, students will enroll in 12 units of research each quarter and begin working on dissertation research and writing until graduation at the end of year four or five. Check out the full list of degree requirements for more information. 

Transferring coursework 

Graduate-level coursework completed at another institution may be substituted for elective or required coursework in some cases, depending on the content of the course. If a graduate-level course was taken during the student’s undergraduate degree program, you must prove that the course was not used to satisfy the bachelor’s degree requirements. Transferred courses are evaluated through an internal process by the instructor of the course at UC Davis. If approved, the course is waived for the student. The waived course does not formally appear on the UC Davis transcript as a transferred course, but does appear on the internal Program of Study form as satisfying the course requirements for the degree. 

Preliminary exam 

Taken in spring quarter of your first year, this exam consists of a 10-minute presentation followed by 20 minutes of questioning by a committee consisting of five faculty members, including your major professor. Prior to the exam, students prepare a one-page abstract containing a general overview and critical assessment of two to three research articles. The exam assesses your ability to communicate a solid understanding of fundamental scientific and engineering concepts, particularly in the context of your research topic. You must complete all core courses and maintain at least a 3.25 GPA to be eligible to take the exam. 

Qualifying exam

Like the preliminary exam, the qualifying exam contains both a written and an oral portion. The written portion consists of a 10-15 page dissertation research proposal and bibliography that follows a format similar to an NSF or NIH grant proposal. After distributing the proposal to the committee, the student prepares a 30-35 minute oral presentation, during which a faculty committee will question the student. The qualifying exam committee consists of four graduate program faculty members and one external faculty member. Major professors are not allowed to participate on the qualifying exam committee. 

Exit seminar 

After you complete your dissertation, you will present your research to the department prior to scheduling an appointment with Graduate Studies to submit your dissertation. At least two of your dissertation committee members must be present at the exit seminar. If the seminar is successfully completed, the committee will sign off on the dissertation signature page. Note that original signatures are required. Scanned images or electronic signatures will not be accepted.

Designated emphases (DE) 

As a doctoral student, you have the unique opportunity to participate in an affiliated designated emphasis (DE). A DE is similar in concept to an undergraduate minor. You will be required to complete additional coursework and must have a faculty member from that DE serve on both the qualifying exam committee and the dissertation committee. Students who successfully complete the DE will have a notation included on their diploma and transcript. The Materials Science and Engineering graduate program is affiliated with three designated emphases:
