Katrina M. Groth is an Assistant Professor in Mechanical Engineering at the University of Maryland. Her research focuses on the safety, risk, and reliability of complex systems. Her work supports decision making for energy and transportation infrastructure, including hydrogen fueling stations, nuclear power plants, aviation, and natural gas transportation. Groth established the Systems Risk and Reliability Analysis Lab (SyRRA) in 2017. Before joining the University of Maryland, Dr. Groth was a Principal Member of Technical Staff at Sandia National Laboratories in Albuquerque, NM, where she led a diverse portfolio of research projects involving quantitative risk assessment, human reliability, and sparse data. Groth developed HyRAM (hyram.sandia.gov), a risk assessment and consequence analysis framework for hydrogen infrastructure. HyRAM enabled the development of the first United States and international safety standards for hydrogen fueling stations (NFPA 2 and ISO 19880-1). Dr. Groth has also made important contributions to the field of human reliability analysis.
