Graduate Programs Guide
Degree Requirements
Doctor of Philosophy
The Ph.D. degree is achieved through an intensive program of coursework and independent research in any one of the following areas: (1) Electrical Sciences and Computer Engineering, (2) Fluid Thermal, and Chemical Processes, (3) Materials Science and Engineering (4) Mechanics of Solids and Structures and (5) Biomedical Engineering. Each Ph.D. student must be affiliated with one of these five research groups, and the faculty in that group will play a central role in defining this program and evaluating student progress.
New Ph.D. students are strongly encouraged to arrange meetings with individual faculty members in their groups during their first semester in residence and to select a research advisor shortly thereafter. At that point, the student, with the approval of his or her advisor, shall devise an appropriate program of study ensuring breadth of knowledge as well as depth of knowledge in a major area that supports the planned dissertation research. The normal residence requirement for the Ph.D. degree is the equivalent of three years of full-time study beyond the Bachelor's degree (i.e. 24 tuition units). At least two semesters beyond the Master's degree must be spent exclusively in full-time study at Brown, although most engineering Ph.D. students spend four to five years in residence at Brown.
General Requirements
The specific requirements for the PhD vary between the different groups. However there are some general requirements that cover all PhD candidates. These can be summarized as:
- Residency Requirement: (University Requirement). The student must complete three years full-time study beyond the bachelor’s degree (i.e. 24 tuition units). Two semesters beyond the bachelor’s degree must be spent exclusively in full-time study at Brown University.
- Research Thesis: The student must write and present (“defend”) a Ph.D. dissertation. The thesis must embody the results of original research and significant creative thought and give evidence of high scholarship. The dissertation and the oral defense must be approved by the faculty advisor, one other member of the engineering faculty, and one additional reader outside the Division, or within the Division but outside the research group, as appointed by the Director of the Engineering Graduate Programs in consultation with their faculty advisor.
- Course Requirements: Students in the Ph.D. program typically take a comprehensive series of courses in the area of their expertise, as well as several other courses in mathematics, physics, engineering and other related disciplines. There is also ENGN 2980: “Reading, Research and Design”, which can be taken for course credit. The number and choice of courses is made in close consultation with the student's advisor who must approve the student's choice at the beginning of each semester. Each research group can define specific courses, which are considered essential for their PhD students.
- Preliminary Examination: This is a comprehensive examination covering the student’s main area of expertise and must be taken no later than the 6th semester of graduate study for a student entering with an Sc.B., and no later than the 4th semester of graduate study for students entering with an Sc.M. The exact timing and format of the exam varies between the different research groups. The details are outlined in the sections below. The results of the examination are presented to the Graduate Committee, along with the student’s academic record, and the recommendations of both the group representative and the student’s PhD advisor. The Graduate Committee then decides whether to certify the student as a Candidate for the degree of Ph.D. in Engineering. In the event of a failing grade, the Graduate Committee will decide whether to re-examine the student, require remedial action, or to request their withdrawal from the graduate program.
- Minor Study: PhD candidates are required to demonstrate proficiency in at least one area outside their main expertise. As with the preliminary examination, the number of minor areas of study, and the method by which proficiency is demonstrated is defined and administered by each of the four research groups.
- Other requirements: Some of the research groups in the division have additional requirements including research proposals, progress summaries. These are outlined in the following section.
RESEARCH GROUP PROCEDURES
Each group administers their respective PhD program and defines the details of coursework, the preliminary exam and other requirements (e.g. progress review). These requirements, along with the details of each group’s administration of the preliminary examination are outlined in the following sections.

Electrical Sciences and Computer Engineering
PROGRESS REVIEW: An oral presentation of approximately 40 minutes duration to a forum of faculty and graduate students summarizing their research progress by the end of October in their 3rd semester (second year in residence). Their academic advisor and at least two other members of the faculty will formally evaluate this presentation and make a recommendation to the Engineering Graduate Committee regarding the student's ability to continue in the Ph.D. program and to undertake doctorate-level research. Students normally prepare for this examination by completing ENGN 2980, and by conducting independent research during the summer months
PRELIMINARY EXAMINATION: With the approval of their academic advisor, students must choose a Preliminary Examination Committee consisting of four examiners. These examiners will conduct an oral examination of the student no later than the end of the sixth semester in residence. Two examiners must be in the student's major research area(s). The two other examiners must be in minor areas outside the student's immediate research area. The Preliminary examination will presume that students are prepared in two minor areas outside the student’s main expertise.
MINOR AREAS: Students are prepared in two minor areas outside the student’s main expertise by completing courses in each of the chosen minor areas, in consultation with their advisor. These areas will be represented by two examiners in their oral preliminary examination.
Fluids Thermal and Chemical Processes
PROGRESS REVIEW: An in-depth faculty review of the student’s progress as of the 2nd semester in the program. This report is shared with the student in writing.
PRELIMINARY EXAMINATION: Students complete a written exam, offered once a year, usually during the January semester break of their 4th semester. Alternative arrangements can be made in special cases. Each student must pass exams in three areas, chosen from among the following topics: Fluid mechanics, Thermodynamics, Transport Processes, Chemical Kinetics and “Special Topics”. “Special topics” allows for an exam in an area that is central to the student’s research, but not covered by the “traditional” four areas. Special topics must be approved (by the student’s PhD advisor and group graduate representative) and arranged well in advance of the examination date. The exam will be administered by the FTCP graduate representative at a designated date and time. The exam is normally of an “open book” format, but the final decision rests with the graduate representative.
MINOR AREAS: The student will, in consultation with their advisor, select one minor area of study satisfied by passing three graduate level courses forming a cohesive subject, but distinct from the student’s main discipline. The student may waive the course count requirement by passing on the preliminary examination a minor area exam. Note that the minor area is not the same as the “special topics” area above, the latter is a major area related to the student’s thesis work.
Materials Sciences
PROGRESS REVIEW: This portion is the official written portion of the preliminary exam taken in their 4th semester. This exam consists of two parts to be taken in two 3-hour sessions. In the morning session, the students will be examined on thermodynamics and kinetics (paralleling the course work in ENGN 2410 and ENGN 2420). In the afternoon session, the students will be examined on mechanical properties and crystallography (paralleling the course work in ENGN 2430 and ENGN 2490).
PRELIMINARY EXAMINATION: Students complete the oral portion of their preliminary exam through a presentation of their proposed researchin their 5th semester. In preparation for this presentation, they will be responsible for reading and understanding a number of seminal papers (typically on the order of 10) critical to the completion of their thesis research. These papers will be chosen in consultation with the student’s adviser and another faculty member chosen by the student and his adviser. During the presentation, the student will be expected to demonstrate understanding of the important scientific and technical issues in his proposed research, as well as an understanding of the relevant issues contained in the assigned papers.
MINOR AREAS: Each student must show proficiency in two minor areas of study. Proficiency is demonstrated by receiving grades of B or higher in the courses constituting the minor. Two courses are required to fulfill the minor, of which at least one must be a 200-level course. The choice of appropriate courses for the minor areas will be determined by the Materials Science graduate student representative. The sequence ENGN 2010 and ENGN 2020 may be used to fulfill the minor requirement in the area of applied math.
Mechanics of Solids and Structures
PROGRESS REVIEW: The progress review is administered during the second semester in residence for students entering with the Masters degree and during the third semester in residence for students entering with the Bachelor of Science degree. It includes a one-half hour oral presentation of independent work by the student, based either on a project in progress or on completed work, and a review of progress in the academic program of study by the examination committee. The committee’s recommendation to the Engineering Graduate Committee following this review as to whether or not a student will be allowed to continue will be based on an evaluation of the research presented and achievements in formal course work. Since students enter the graduate program with diverse backgrounds, this Review also should establish whether or not deficiencies exist in a student's preparation and, if so, he or she will be so advised. The subsequent program can then be planned to correct any deficiencies prior to the taking of the Preliminary Examination.
PRELIMINARY EXAMINATION: In the 5th semester an oral examination of approximately two hours duration is designed to test the student's knowledge of the major field of study as well as knowledge of two minor fields selected by the student and the research advisor. The student is expected to demonstrate a sound grasp of the fundamental concepts and methodologies of the major field, and to demonstrate a proficiency in specific topics in the minor areas. The examination committee consists of a major area examiner, one examiner in each to the two minor areas, the Graduate Representative, and the student’s research adviser. This committee reports on the outcome of the examination to the Engineering Graduate Committee; if the performance is unsatisfactory, it also makes on recommendation on whether or not the examination may be repeated after a certain time has elapsed.
MINOR AREAS: The Preliminary Examination will presume that the student has a level of knowledge in each of two minor areas corresponding to successful completion of two graduate courses in each of the minor subjects. Possible minor subjects include Applied Mathematics, Materials Science, Physics, Biology, Geology or another discipline in engineering or science. If Applied Mathematics is to be one of the minor areas, two courses beyond ENGN 2010 and ENGN 2020 or equivalents should have been successfully completed.
