The Department of Civil and Environmental Engineering offers three graduate degrees: Doctor of Philosophy (Ph.D.), Master of Science in Engineering (M.S.E.), and Master of Engineering (M.Eng.). Students must be admitted to one of these three degree programs. For each of these degree programs, the department offers individualized tracks of graduate study that are aligned with the following research areas:

  • Mechanics, Materials, and Structures                 
  • Architecture, Arts, and Archaeology
  • Hydrology and the Atmospheric Environment  
  • Sustainable, Resilient Cities and Infrastructure Systems
  • Chemistry, Biology, and Technology                  
  • Water, Climate, and Energy

The student-faculty ratio in the department is kept small to allow for productive working relationships between students and their advisers. The department maintains an atmosphere where close interaction between students and faculty is the norm, whereby students benefit from the background, experience, and knowledge their advisers have gained in solving important engineering problems.

Program Offerings

Program description

When a Ph.D. student enters the department, an adviser is assigned to the student based on the student's area of interest.

Every admitted Ph.D. student is given financial support in the form of a first-year fellowship.

In addition, all admitted Ph.D. students are automatically considered for the prestigious Wu and Upton Fellowships.


Demonstrated proficiency in appropriate coursework is required for the Ph.D. degree. Most of this coursework needs to be completed prior to the General Examination. Courses required for admission to the General Examination are as follows:

  • CEE 509 - Independent Study I
  • CEE 510 - Independent Study II
  • 2 applied mathematics or computational methods courses
  • 6 additional courses covering depth in, and breadth around, one's research

CEE 509 and 510: The CEE 509/510 requirements are meant to demonstrate the requisite abilities to carry out advanced independent research. These requirements must be completed by the end of the semester of the General Examination.

Applied mathematics or computational methods: The mathematics/computational methods requirements are meant to provide a strong foundation in quantitative skills.  The requirement may be fulfilled by courses in advanced calculus, probability, data science, statistics, numerical methods, scientific computation, or related fields.

Specialized knowledge courses:  Each student must complete at least three courses that focus on the student's specific research. These courses are directly related to the foundational knowledge of the Ph.D. thesis research, and they ensure that the student has a firm grasp of relevant fundamentals. At least three specialized knowledge courses must be completed by the end of the semester of the General Examination.

The breadth of knowledge courses:  In addition to taking courses in specialized subjects, students must broaden their education beyond the intellectual boundaries of their own research. This is important for success in future academic or non-academic careers, given the complexity of modern civil and environmental challenges and the need for interdisciplinary teams to solve them. To be active members or future leaders of such teams, students must be able to converse and understand a range of issues, concepts, and approaches that are far wider than their detailed research specialization. Each student must demonstrate proficiency in at least three "breadth" courses.  These courses must cover multiple areas outside the student’s core research area. One of the breadth courses may be taken after the General Examination. 

Grade requirements:  All required Ph.D. coursework must be taken for a grade (no P/D/F, no audit). The average grade of all graduate courses in the student’s overall program of study must a "B" (3.00) or better.

General exam

Students are expected to take the general examination within the first two years of Ph.D. studies. Students are not normally readmitted to a third year (fifth term) of graduate study unless they have taken the General Examination. No student will be readmitted to a fourth year (seventh term) of graduate study without successful completion of the General Examination.

In cases where equivalent and relevant graduate coursework has been completed before enrollment as a Ph.D. student at Princeton, a student may propose to use that prior coursework to satisfy one or more course requirements and demonstrate coursework proficiency. A student must submit to the DGS a copy of the syllabus and other supporting material for review by CEE faculty before submitting the General Exam Request Form. This material must be submitted by the end of the first semester of Ph.D. study at Princeton. Note that prior coursework from undergraduate studies, even if taken at the graduate level, is unlikely to be approved as a substitute for the coursework requirements.

General Examination Request form: The General Exam Request Form consists of the student's plan to meet the coursework proficiency requirements, the title of the Ph.D. research, and the research abstract. The form, normally submitted in the semester before taking the General Examination, is reviewed by CEE faculty to ensure demonstrated proficiency in relevant subject areas. For plans that are not approved, feedback is given to the student to modify the plan. Once approved, any deviations from the approved coursework plan must be submitted to the faculty adviser and DGS. A full review by the CEE faculty may be required for substantial coursework changes.

Research Proposal: A dissertation research proposal is due to the Graduate Program Administrator in advance of the General Examination. This document forms the basis of the student's General Examination oral presentation. It must demonstrate adequate background knowledge, clear and concise communication skills, and the ability to plan and formulate a research project.

Examination Structure: The General Examination Committee consists of four to six examiners, of whom at least three are CEE faculty members. The student’s adviser normally chairs the Committee. The General Examination is scheduled for up to three hours and is conducted as an oral examination. The General Examination consists of a presentation by the student, followed by questioning from the committee on the presentation material, as well as broader topics related to the student’s research preparation. The basis of the presentation must be the written Research Proposal. The presentation will typically last 30-40 minutes. The General Examination Committee provides a written evaluation to the DGS of the sufficiency of the student's preparation and knowledge to undertake the proposed dissertation research.

Qualifying for the M.A.

The Master of Arts (M.A.) degree is normally an incidental degree on the way to full Ph.D. candidacy. It is earned after a student successfully completes the required coursework and the general examination.  It may also be awarded to students who, for various reasons, leave the Ph.D. program, provided that the coursework requirements have been met and the sections of the general exam showing proficiency and scholarship have been passed.  In such cases, it is not required that students have completed the part of the general exam involving a research seminar based on a dissertation proposal.

Students admitted to the Ph.D. program who do not wish to complete the program may be considered for an M.S.E. degree with approval from the department and the Graduate School.  Ph.D. students who have already been awarded the incidental M.A. are not eligible to earn an M.S.E.


Teaching experience is considered to be a significant part of graduate education. It is recommended that Ph.D. candidates assist with course instruction for at least one term.

Post-Generals requirements

Yearly Meetings with Research Committee
Upon completing the general examination, students must have a research committee consisting of the adviser and two or more additional faculty members. The research committee meets with the candidate at least once per academic year to supervise the research and provide feedback.

Dissertation and FPO

Final public oral (FPO) examination: Upon completion and acceptance of the dissertation by the Department, the candidate will be admitted to the final public oral examination.

The Ph.D. is awarded after the candidate’s doctoral dissertation has been accepted and the final public oral examination sustained.

Program description

The M.S.E. program has a strong research focus, including coursework, culminating with the requirement of an M.S.E. thesis.  The M.S.E. is usually completed within two academic years of full-time study. Financial support in the form of a research or a teaching assistantship may be available for students enrolled in this program.


The course requirements are fulfilled by successfully completing 10 one-semester courses, two of which are the required research courses (CEE 509 Independent Study I and CEE 510 Independent Study II). The M.S.E. degree is usually completed within two academic years of full-time study.


The M.S.E. program has a strong research focus reflected in the requirement of a master’s thesis. By the second term of study, a committee consisting of the adviser and one additional faculty member is formed to guide and supervise the candidate's thesis research. Candidates must prepare and submit an acceptable thesis as well as present an open seminar on their research.

This program is not currently accepting applications.

Program description

A Master of Engineering degree is offered to students interested in the applied aspects of engineering and wish to prepare for professional practice and consulting. There is no research required for this degree program. The M.Eng. degree is completed in one academic year of full-time study.

There is no financial support for students in this degree program. Students interested in research-focused degrees should apply to the M.S.E. or Ph.D. degree programs instead, where financial support through teaching and research is available.

Students interested in the M.Eng. degree should contact the departmental director of graduate studies before application. The program also provides formal study in nontechnical areas such as corporate finance, public policy, and regulatory issues.


A student fulfills the requirements by successfully completing 8 one-semester courses. The coursework is intended to be at the graduate level (500), though specific undergraduate courses may be approved in advance by the student’s adviser and Director of Graduate Studies. No more than four courses may be taken at the undergraduate level. The average grade of all graduate courses in the student’s overall program of study must be 3.0 or better.  All courses must be taken for a grade, and any PDF or audit courses will not be counted toward course requirements.
