Program Title and Classification

Reliability Engineering

Graduate Degree Program

College: Engineering


Reliability Engineering is an interdisciplinary program of the Department of Mechanical Engineering. The academic and research programs are based upon the recognition that the performance of a complex system is affected by engineering inputs that begin at conception and extend throughout its lifetime. Students may specialize in Assessment (Root-Cause Failure Analysis, Probabilistic Risk Assessment, Common-Cause Failures); Testing and Operation (Operator Advisory Systems, Human Reliability, Software Reliability); Manufacturing (Statistical Process Control, Improved Manufacturing Methods); Component and Structures Reliability (Microelectronics and Materials); or Electronic Packaging Reliability.

Admissions Information

General Requirements:

Program-Specific Requirements:

  • Letters of Recommendation (3)
  • Graduate Record Examination (GRE)
  • CV/Resume
  • Publications/Presentations

The Program offers graduate study leading to the Master of Science, Professional Master of Engineering (offered through the Office of Advanced Engineering Education), and Doctor of Philosophy degrees and is open to students who have a Bachelor of Science degree in engineering, physics, or mathematics and obtained a GPA of at least 3.0 on a 4.0 scale from accredited programs. An individual plan of graduate study compatible with the student’s interest and background is established by the student in consultation with an advisor. In some cases, it may be necessary to require background courses to fulfill prerequisites.

Degree Requirements

Master of Science (M.S. )

Total CreditsCore RequirementsSpecialization Options

Thesis option: 30 credits

Non-thesis option (scholarly paper): 30 credits

ENRE 600: Fundamentals of Failure Mechanisms (3 credits)

ENRE 602: Reliability Analysis (3 credits)

Thesis option: Six credits of ENRE 799: Master's Thesis Research are required.

Non-thesis option: Scholarly paper is required. 


The M.S. degree program offers thesis and non-thesis options. The thesis option requires 24 credit hours of coursework and 6 credits of thesis research. Students who enroll directly in the Ph.D. program or students who transfer into the Ph.D. program from the M.S. program by passing the Ph.D. qualifying examination may obtain a non-thesis M.S. degree upon advancing to doctoral candidacy. The non-thesis option requires 30 credit hours of coursework, a scholarly paper, and presentation. All students must complete the Program Core requirements as well as all of the Graduate School requirements.

The Professional Master of Engineering (M.Eng.) program in Reliability does not require a thesis, but students must complete at least 30 credits of approved coursework.


Doctor of Philosophy (Ph.D.)

Core Requirements

1. Doctoral students compile a program of study with their advisor, which is then submitted to the Graduate Studies Office of the Department of Reliability Engineering for approval. This should be submitted in the first semester of study.

2. Doctoral students must complete 36 credits of courses with at least 30 credits at the 600 level or above, including the required courses for the M.S. degree (ENRE 600 and 602). 

3. In addition, students must complete 12 credits of ENRE 899: Doctoral Dissertation Research.

4. Students must pass the Ph.D. qualifying examination and successfully produce and defend a Ph.D. dissertation on an original research topic after the core courses and at least two additional ENRE elective courses are taken.


For the Ph.D. degree, students must complete a minimum of 36 credits of approved graduate courses (a minimum of 18 credits of coursework at the University of Maryland) and 12 credits of dissertation research, with a minimum 3.0 GPA overall. In addition, students must pass the Ph.D. qualifying examination and successfully produce and defend a Ph.D. dissertation on an original research topic after the core courses and at least two additional ENRE elective courses are taken. The GPA for these four courses must be 3.5 or higher.


Facilities and Special Resources

Students and faculty have access to a host of special facilities in the College of Engineering, including the nuclear reactor, an 8-MeV electron linear accelerator; environmental chambers; mechanical testing, SEM, X-ray and imaging facilities; and extensive computer resources. The program also has a complete failure analysis laboratory.

Financial Assistance

Financial assistance is available to highly qualified students in the form of research and teaching assistantships. The most outstanding applicants are offered fellowships. Students seeking financial assistance are asked to submit with their applications a current resume or CV as well as a statement regarding their qualifications and/or past research or teaching experience. Financial assistance is sought for all worthy students.
