Biography

Zahra Mohaghegh is an Associate Professor and Donald Biggar Willett Faculty Scholar in the Department of Nuclear, Plasma, and Radiological Engineering at the University of Illinois Urbana-Champaign (UIUC).  She is the Director of the Socio-Technical Risk Analysis (SoTeRiA) Research Laboratory at UIUC, advancing risk science and applications for the safety and economic viability of complex technological systems such as commercial nuclear power plants and advanced reactors, civil aviation, and oil industries. Mohaghegh has conducted research on probabilistic risk assessment, probabilistic physics of failure analysis, human-system reliability modeling, risk-informed decision-making, and uncertainty analysis, benefiting from grants awarded by the U.S. Department of Energy, National Science Foundation, Nuclear Regulatory Commission, nuclear power industry, and the International Atomic Energy Agency. She received the National Science Foundation Mid-Career Advancement Award, George Apostolakis Award in risk assessment, and the American Nuclear Society Mary Jane Oestmann Professional Women’s Achievement Award for her pioneering in the introduction of human and organizational factors into the risk analysis of socio-technical systems in nuclear and other high-risk industries. Mohaghegh has consistently applied her expertise in nuclear risk analysis to a wide array of technological challenges, enhancing policymaking and regulation across sectors; for example, she served as a member of the Committee on “Transport Airplane Risk Assessment Methodology” of the U.S. National Academies of Sciences, Engineering, and Medicine, and is currently a member of the U.S. National Academies’ Committee on “Improving the Efficiency and Effectiveness of the Coast Guard Certificate of Compliance Examination Program for Gas Carriers.”
