Before retiring from the University of Wisconsin-Madison (UW) as a Distinguished Research Professor, Dr El-Guebaly was the: Nuclear Group Leader at the UW Fusion Technology Institute Nuclear Task Leader for the multi-institutional ARIES and FNSF fusion projects U.S. Contact Person for the IEA Task on Fusion Radioactive Waste Studies. Her primary interest is in the area of neutronics, activation, radiation shielding, and radwaste management for both D-T and D-3He fueled plants for terrestrial and space applications. She has extensive experience in experimental and power plant designs and was involved in the conceptual designs of numerous national and international fusion concepts: magnetic (tokamaks, spherical tori, stellarators, FRC, and tandem mirrors) and inertial (laser, heavy ion, and Z-pinch). She participated in over 25 multi-institutional fusion design studies and was also involved in several small-scale projects focusing on space, advanced D-3He fuel, component testing, radioactive waste management, proliferation-resistance, and non-electric applications. She published extensively in fusion contexts, authoring ~300 technical reports and scientific publications in U.S. and international refereed journals and contributing nine chapters on fusion-related topics to books on nuclear energy. She now currently offers consulting in several areas of fusion technologies, including the environmental aspect of fusion.
