The Center for Risk and Reliability (CRR) was formed in 1985 as the umbrella organization for many of the risk and reliability research and development activities at the UMD Clark School of Engineering. CRR research covers a wide range of subjects involving systems and processes, and include topics on predictive reliability and human reliability analysis methods, advanced probabilistic inference methods, system-level health monitoring and prognostics, risk analysis theory and applications to complex systems such as space missions, civil aviation, nuclear power plants, petro-chemical installations, medical devices, information systems, and civil infrastructures. Over 20 core and adjunct faculty from various engineering departments of the Clark School of Engineering form the pool of experts at CRR. CRR is also home to numerous research laboratories with extensive state-of-the-art equipment and high performance computers.

CRR is the research arm of the Reliability Engineering educational program, one of the largest and most comprehensive degree granting graduate programs in the field of reliability and risk analysis of engineered systems and processes. The program offers the MS, PhD, and Graduate Certificate in Reliability Engineering and Risk Analysis. All courses are available through both traditional on-campus and online delivery modes.

Due to its interdisciplinary nature, CRR is under the administrative umbrella of the Dean of the A.J. Clark School of Engineering. The Center is administratively supported by the Mechanical Engineering Department, the home department for its current full-time core faculty. The Center Director is appointed by the Dean for a 5 year term and is a member of the Dean's Administrative Council composed of the College of Engineering Chairs and Directors. 

Center for Risk and Reliability (CRR) has been a major research and education resource since the mid-1980s and assumed a new mission in 2003 by combining two very successful centers. This Center is an umbrella organization within the A.J. Clark School of Engineering at the University of Maryland, College Park, which provides expertise and cutting-edge research on methods and tools to perform risk and reliability assessment of structures, complex systems and processes for space, military and civil aviation, nuclear energy, and petroleum industries. More recently, CRR has provided leadership in new frontiers that include Healthcare Systems Risk Management and Medical Device Reliability, Prognostics and Health Management of Complex Systems and Structures, and Resilience Engineering. Several governmental and private organizations continue funding CRR's research. The mix of research sponsors remaina at a roughly 50/50 split between industry and government agencies, with reliability engineering research being funded mostly by the industrial sponsors, while risk and safety research studies sponsored by the Federal and State government agencies.

We at the CRR take extreme pride at offering the Reliability Engineering Graduate Program which continues to attract highly talented graduate students and a steady stream of visiting scholars from US and international universities, research centers, government agencies and companies. The educational program of the CRR has provided a large number of tremendously successful alumni that have been making major contributions to the field of risk and reliability in the past 25 years.
