Center for Risk and Reliability
Katrina Groth is an Assistant Professor in Mechanical Engineering at the University of Maryland. Dr. Groth is the associate director for research for UMD's Center for Risk and Reliability and the director of the Systems Risk and Reliability Analysis lab (SyRRA). Groth’s research focuses on the development of models and computational methods for risk analysis of complex engineering systems. Her research blends reliability engineering, probability theory, causality, Bayesian methods, machine learning and cognitive science to provide human-focused insights. Groth’s research has enhanced system safety, U.S. policy, and international regulations for applications including hydrogen fueling stations, oil and gas infrastructure, commercial aviation, and nuclear power.
Prior to joining UMD, she served as Principal R&D Engineer at Sandia National Laboratories, where she led multiple projects in probabilistic risk assessment, human reliability analysis and hydrogen safety. Groth developed HyRAM (hyram.sandia.gov), a risk assessment and consequence analysis framework for hydrogen infrastructure, which enabled development of the first United States and international safety standards for hydrogen fueling stations (NFPA 2 and ISO 19880-1). Groth has published over 50 journal and conference papers, 30 technical reports, and 2 software packages, and holds 1 patent. She received her Ph.D. in Reliability Engineering from the University of Maryland in 2009. She also holds an M.S. in Reliability Engineering and B.S. in Nuclear Engineering from UMD. Groth is also a trustee for the National Museum of Nuclear Science & History.
