Katrina Groth is an Assistant Professor in Mechanical Engineering at the University of Maryland. 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 engineering safer systems through models and computational methods for risk analysis of complex engineering systems. Her research blends model-based thinking with computational, data-driven methods, drawing from reliability engineering, probability theory, causal modeling, Bayesian statistics, machine learning and engineering science. She is a recognized expert in hydrogen safety, probabilistic/quantitative risk assessment and human reliability analysis. Groth’s research has enhanced system safety, U.S. regulations and policy, and international codes and standards for applications including hydrogen fueling stations, natural gas and fuel cell vehicles, oil and natural gas pipelines, commercial aviation, and nuclear power.
